href=\"https:\/\/mooser-consulting.de\/en\/services\/components-measurement\/\">These components can be tested for EMC aspects individually or in combination at variable speeds and torques<\/a> . The key data of the eCHAMBER<sup>\u00ae<\/sup> alone are impressive. An installed drive and brake power of up to 250 kilowatts, voltages of up to a 1000 volts and currents of up to 500 amperes leave nothing to be desired when it comes to testing. The chamber is used to test powertrains with peak outputs of up to 500 kilowatts. For electric drive systems in buses and trucks, Mooser has also developed an eCHAMBER<sup>\u00ae<\/sup> with even larger dimensions to meet the requirements of large test objects (up to 1000 kilograms). The first eCHAMBER<sup>\u00ae<\/sup> went into operation in 2008 at Mooser in Ludwigsburg. In the meantime, EMC specialists in China and South Korea are also optimising their systems using Mooser\u2019s eCHAMBER<sup>\u00ae<\/sup>. The four eCHAMBER<sup>\u00ae<\/sup> units currently in operation in the Mooser laboratories and a further five operated by customers have impressively demonstrated their capabilities in numerous

Our engineers were the first to provide evidence through measurement that electromagnetic interference originating from an inverter (a very strong emitter of electromagnetic interference) or an electric motor can couple through the drive shaft directly into the gear wheels of the transmission and be conducted further into the drive axles. The axles then radiate this interference, resulting in interference to radio reception.<\/p><p>An important prerequisite for this type of EMC measurement is that the electric motor is actually rotating during the test. If the motor was stationary, the disturbances coming from the coils would be short-circuited through the output shaft and the ball bearings and would be largely eliminated. On the other hand, if the electric motor is rotating, the oil film on the ball bearings forms an insulation layer, thus causing the electromagnetic interference from the motor to be completely conducted through the shaft and into the transmission. In the eCHAMBER\u00ae, we can measure the disturbances on the axles and shafts and, on the basis of these measurements, we can propose measures for decoupling the path between the electric motor and the axles. The high-frequency disturbances on the shaft not only cause interference in radio and telephone reception. They can also become apparent in the form of high-frequency discharges, which can result in premature bearing damage.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-93eaca7 elementor-section-full_width elementor-section-height-min-height elementor-section-height-default elementor-section-items-middle\" data-id=\"93eaca7\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-95efd99\" data-id=\"95efd99\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-ea1e39b elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"ea1e39b\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-c76f8d6\" data-id=\"c76f8d6\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-194c983 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"194c983\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-no\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-66 elementor-inner-column elementor-element elementor-element-d7f8761\" data-id=\"d7f8761\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-f55b007 elementor-widget elementor-widget-heading\" data-id=\"f55b007\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Not only troubleshooting, but also system optimization<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5dca7af elementor-widget elementor-widget-text-editor\" data-id=\"5dca7af\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>In addition to the <a href=\"https:\/\/mooser-consulting.de\/en\/services\/components-measurement\/\">component and system tests<\/a>, we also offer our customers a <a href=\"https:\/\/mooser-consulting.de\/en\/services\/emc-consulting\/\">qualification and further development service for components and systems<\/a>. In order to reduce electromagnetic emissions, we recommend such measures as improving the circuit layout, using different components, changing the wiring routing, using larger surfaces for electrical grounding or improving the ground connections.<\/p><p>In addition, customers can benefit from our detailed advice on testing procedures and measuring methods as well as on the vehicle layout. We also use the eCHAMBER<sup>\u00ae<\/sup> to determine the distances between EMC-critical components to ensure immunity to interference, for example between a traction motor at the front axle and the adjacent electric power steering system. To do this, we first measure the interference emissions of the traction motor and compare them with the interference immunity of the power steering motor. We then use these two parameters to calculate the distance required between the two components to ensure interference immunity. Until now, such measurements were only possible at the original installation location in the vehicle, and the measuring conditions were very difficult.<\/p><p>Mooser is also known for its good ideas and reliability when it comes to carrying out customers\u2019 projects. For example, a Mooser engineer will accompany the customer\u2019s project from start to finish. . A fixed contact partner is always on hand to liaise with the customer and deal competently with their questions. And a further benefit is the fact that our employees take great care in preparing the test reports.

the devices under test save time and costs. In the past, the further development of electric drive components to optimise their EMC took place both in the vehicle and on the test bench. For example, replacing a capacitor in the inverter meant that the prototype vehicle first had to be dismantled in the large EMC measuring hall and placed on a lifting platform. In the hall, the inverter and possibly some other components had to be removed from the vehicle. The capacitor was then replaced and the inverter was reinstalled in the vehicle, which was then taken back into the measuring hall and reassembled. These dismantling and reassembly times and the unproductive time in the measuring hall cause high costs \u2013 and all the more so with complex drive trains such as a plug-in hybrids.<\/p><p>By contrast, Mooser\u2019s eCHAMBER<sup>\u00ae<\/sup> makes it possible to complete these development steps much more quickly. The inverter can be removed, prepared and reinstalled very easily. In the end, this saves a lot of set-up time and cuts costs Many concrete examples from car makers have shown that Mooser\u2019s test bench-based development process can reduce the costs of test bench time, personnel and measuring work by more than 95 percent in some cases.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-08b0f52\" data-id=\"08b0f52\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-1265710 elementor-widget elementor-widget-heading\" data-id=\"1265710\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Measurement quality<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9ad9e70 elementor-widget elementor-widget-text-editor\" data-id=\"9ad9e70\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The eCHAMBER<sup>\u00ae<\/sup> and the other state-of-the-art testing facilities from Mooser are accredited according to DIN EN ISO\/IEC 17025.

Many concrete examples from car makers have shown that Mooser\u2019s test bench-based development process can reduce the costs of test bench time, personnel and measuring work by more than 95 percent in some cases.<\/p><p>In the past, the further development of electric drive components to optimise their EMC took place both in the vehicle and on the test bench. For example, replacing a capacitor in the inverter meant that the prototype vehicle first had to be dismantled in the large EMC measuring hall and placed on a lifting platform. In the hall, the inverter and (possibly some other components) had to be removed from the vehicle. The capacitor was then replaced and the inverter was reinstalled in the vehicle, which was then taken back into the measuring hall and reassembled.<\/p><p>These dismantling and reassembly times and the unproductive time in the measuring hall cause high costs \u2013 and all the more so with complex drive trains such as a plug-in hybrids. By contrast, Mooser\u2019s eCHAMBER <sup>\u00ae<\/sup> makes it possible to complete these development steps much more quickly. The inverter can be removed, prepared and reinstalled very easily. In the end, this saves a lot of set-up time and cuts costs<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1346\" class=\"elementor-tab-title\" data-tab=\"6\" role=\"button\" aria-controls=\"elementor-tab-content-1346\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><i class=\"icon icon-down-open-big\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><i class=\"elementor-toggle-icon-opened icon icon-up-open-big\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">What is \u201chigh voltage\u201d? <\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<div id=\"elementor-tab-content-1346\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"6\" role=\"region\" aria-labelledby=\"elementor-tab-title-1346\"><p>When systems and components in a vehicle are operated at voltages that exceed 30 volts AC or 60 volts DC, engineers refer to these as high-voltage (HV) systems.

An eCHAMBER\\u00ae is used to carry out EMC tests on electric motors, inverters, transmissions, clutches, hybrid transmissions, drive shafts and axles. These components can be tested for EMC at variable speeds and torques, either individually or in combinations. In the meantime, EMC specialists in China and South Korea are also optimising their systems using the eCHAMBER\\u00ae. The nine eCHAMBER\\u00ae units currently in operation in the Mooser laboratories and at customers have demonstrated their capabilities in numerous component and powertrain tests.<\\\/p>\"}},{\"@type\":\"Question\",\"name\":\"What advantages does the eCHAMBER\\u00ae have compared to other measuring concepts?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"<p>The reproducible tests in the eCHAMBER <sup>\\u00ae<\\\/sup> and good accessibility to the devices under test save time and costs. Many concrete examples from car makers have shown that Mooser\\u2019s test bench-based development process can reduce the costs of test bench time, personnel and measuring work by more than 95 percent in some cases.<\\\/p><p>In the past, the further development of electric drive components to optimise their EMC took place both in the vehicle and on the test bench. For example, replacing a capacitor in the inverter meant that the prototype vehicle first had to be dismantled in the large EMC measuring hall and placed on a lifting platform. In the hall, the inverter and (possibly some other components) had to be removed from the vehicle. The capacitor was then replaced and the inverter was reinstalled in the vehicle, which was then taken back into the measuring hall and reassembled.<\\\/p><p>These dismantling and reassembly times and the unproductive time in the measuring hall cause high costs \\u2013 and all the more so with complex drive trains such as a plug-in hybrids. By contrast, Mooser\\u2019s eCHAMBER <sup>\\u00ae<\\\/sup> makes it possible to complete these development steps much more quickly. The inverter can be removed, prepared and reinstalled very easily. In the end, this saves a lot of set-up time and cuts costs<\\\/p>\"}},{\"@type\":\"Question\",\"name\":\"What is \\u201chigh voltage\\u201d?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"<p>When systems and components in a vehicle are operated at voltages that exceed 30 volts AC or 60 volts DC, engineers refer to these as high-voltage (HV) systems. Employees in car workshops are required to undergo additional training before they are allowed to work on such vehicles. In this context, maintenance work means all those jobs that involve such things as disconnecting the HV system, replacing individual HV components or working on disconnected HV components. Various organisations and companies offer training courses for working on HV systems. The term \\u201chigh voltage\\u201d in this context, which merely refers to voltages above a certain threshold, should not be confused with the term \\u201chigh voltage\\u201d that is used in electric power engineering, where voltages are much higher.<\\\/p>\"}}]}<\/script>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Tailor-made test bench concept for high-voltage electric drive systems: the Mooser eCHAMBER\u00ae The eCHAMBER\u00ae sets new standards with its innovative drive concept, revolutionary measuring methods and the highest measuring precision.
