printable version torquemotor-teststand

Electrification of vehicle drives is coming up more and more. The battery is the most important object. Till today weight of the enery content is 10 times of that with gasoline. And the costs are a lot. Energy balance is only then ok if charging current is generated by regenerative means. All these developments are going on. If the battery is heavy then the vehicle itself must be eased, new material is being developped for that purpose.

Training of vehicle experts is needed for the fundamentals of this new technology. TeLC want to help here with ist new teststand.

Build-up:

Torque engines of any kind can be coupled to the receptor flange on the platform. One direct and one geared drive belong to the equipment. The flange is coupled with a three phase engine by means of a Poly-V-beltdrive
Three phase engine is equipped with variable speed control.and torque measurement. Power of that engine is as high to govern the speed.

LC display on the cabinet indicates measure values T, v, V, C, Pm, Pel, c , turning-increments, Vcontr.. Serially connected to computer, data acquisition can be made with TeLC software

One part of the cabinet can be opened from behind. This allows access to in- and outputs of the controller with help of external instruments like multimeter or oscilloscope.

Technical data of the teststand:

  • motor power up to 600W
  • torque max. 60 Nm
  • speed max 400 rpm
  • brushless test engines with external / inbuilt controller
  • built-in Li-Battery
  • built-in charger
Testing of:

  • Generated powers
  • Braking powers (recuperation)
  • Battery charging
a
The operational functions on the teststand:
  • Multifunctional control wheel for speed governing by the 3-ph.motor and switching drive / brake function and diagnosis
  • Battery discharging / charging
  • On/off controller torque-engine
  • 3+5 socket motor connection
  • display clamp and power regulator
  • Braking with the torque engine
a

Experimental possibilities:

  • Torque characteristic versus speed
  • Current consumption / reach at different loads
  • Braking performance and recuperation
  • Charging performance of batteries

Discrete Measurement on in- and outputs of the controller
Part of the cabinet can be opened from behind. Controller, charger, battery and all connectors are visible and accessable. With help of external measure instruments status, voltages and currents can be measured.
