Motor test bench

Motor test bench – also for rent

Based on our experience with electric drive systems – consisting of an inverter, electric motor and, if necessary, gearbox – we have designed and implemented our own test bench. We use the test bench for further developing motors as well as the VECTOPOWER inverters.

In addition, this powerful and adaptable test bench, including expert personnel, is also available for third parties.

Comprehensive service

We provide you with the test bench according to your requirements, including qualified personnel.

Flexibility

You will receive all previously agreed results and evaluations and can, of course, be present with your own personnel. This allows you to readjust measuring programs even after initial measurement results.

Certified according to ECE R85

Our test bench is accredited for measurements according to ECE R85 (measurement of the nominal power), which the TÜV carries out together with us and then submits to the KBA for obtaining the certificate for a drive train.

Confidentiality guaranteed

Access privileges are limited both physically and electronically to our test bench team. We will be happy to provide you with a binding confidentiality agreement.

Customer benefits

Characteristics of a newly developed motor can be precisely determined or confirmed
Exact determination of the characteristics of electric motor-inverter combinations
In the case of an ECE-R85 measurement, the TÜV approval for the type approval can also be organized
The test bench was developed from our own application experience and therefore offers a particularly high level of practical relevance

Technical data

In the power range up to 500 kW we cover the following requirements:

Torques currently up to 4000 Nm
Speeds up to 3500 rpm
High accuracy in the measurement of torque, power, and efficiency
Measurements accredited according to ECE-R85
Test specimens adjustable from 35 °C to 65 °C with cooling medium

Measurements on the motor as well as on the motor-inverter combination
Efficiency maps for motors, inverters, and combinations of these components
Variable voltage level for simulation of the battery characteristic curve from 100 to 700 VDC
Adaptations also possible for motor-gearbox combinations
Individual measurement procedures according to your specifications

Functions of the motor test bench

A wide range of measurements can be carried out on the test bench. The most important measurable characteristics include:

Electrical characteristics
Efficiencies
Thermal characteristics
Special measurements such as drag tests in no-load operation or active short circuit

Typical application scenarios

Determination of the characteristics of the motor, inverter, and motor-inverter combinations
Determination of efficiency maps
Measurements for obtaining the ECE-R85 type approval
Investigation of the behavior at special operating points and their interactive optimization
Running of preprogrammed load cycles with determination of power consumption, thermal behavior, and much more
