Measuring and checking, torque measurement

Test bench structure with a magnetic powder brake to take up characteristics and performance data and integrated torque measurement for the characteristic measurement of motors, gears, pumps, fans etc.

This system approved itself by its compact design at high torques and low  exciting performance.It is used successfully in the training area, for serial manufacturing and product control.

The torque can be controlled and regulated via a large speed range.

For its use the model range in the area from 5-200 Nm can be expanded by a large number of periphery techniques.

Size I	5 Nm	50 watt		Size IV	65 Nm	250 watt
Size II	12 Nm	130 watt		Size V	120 Nm	550 watt
Size III	35 Nm	200 watt		Size VI	200 Nm	750 watt

The constant current controller Type R 2302 Z with superposed torque control offers the complete solution.

Table technical data

Magnetic powder brakes

	for the load measurement in the test bench
	to measure and check the performance and torque

The magnetic powder brake achieves at low gate power a high torque which is independent from the slip speed.

The characteristic of the magnetic powder brake is a great advantage for the control engineering.

Chart characteristics

Magnetic powder brakes for measuring the load in the test bench

The torque to be transferred and the exciting current behave t to each other in about proportionally.

 +
In case of a fixed exciting current, the torque is independent from the slip speed.


When switching on, the torque builds up itself time-delayed. DC switching results in shorter switching times than switching on the mains side.
