Simple operation
Thanks to the flexible autfactory test bench software, the test process is easily configurable and requires no programming knowledge.
We have developed a customized laboratory test bench for a leading Tier 1 supplier to the automotive industry, which is specially designed for testing electric motors in the prototype phase and for small series production. With its comprehensive test coverage and modular expandability, this test bench enables precise quality control and meets the high standards of the automotive industry.
With this laboratory test bench for electric motors, AUTFORCE offers a high-performance, flexible solution that meets the requirements of modern electric motors and ensures reliable quality control with the help of measuring systems from our technology partner Dewetron.
The entire test run is started and monitored by the operating personnel, with the autfactory test bench software taking over the automated process. The steps in detail:
The electric motor undergoes a previously defined test sequence in which all critical parameters are systematically checked. This ensures a complete assessment of the performance and safety of the electric motor:
First, the insulation resistance is measured to ensure that no leakage currents occur and that the motor is safely protected against short circuits.
The insulation test is followed by a check to ensure that the phase resistances are within the tolerance range and that there are no imbalances in the windings.
The motor’s temperature sensor is checked for accuracy and functionality. In addition, temperature compensation is carried out using an infrared thermometer.
The high-voltage fuse is tested to ensure that the motor switches off properly in the event of voltage faults.
In this step, the direction of rotation of the motor and the function of the resolver, which is responsible for the precise control of the motor, are checked.
The generated reverse voltage of the motor is measured in order to evaluate the efficiency and performance of the motor.
Finally, the drag torque is measured to determine the engine’s friction losses at idling speed.
