| Abstract |
A testbench for electric vehicle drives must be able to measure all significant parameters of these drives.
For this the testbench must fulfill all requirements of the drive relative to power, speed and torque and
also to thermal demands. The here presented testbench has the nominal values of a continuous power of
100 kW and a continuous torque of 238 Nm. The testbench motor runs up to a speed of 8,000 rpm. With
gearboxes the speed or the torque can be increased. The testbench is equipped with a measurement
system for d.c. power, three phase a.c. power, speed, torque and temperature. Also a special cooling and
heating device for the testing of liquid -cooled systems is available. |
