onneCtions

Connect all items together. The dynamometer controller and speed readout (if applicable)
interconnections are straight forward using the cord sets.

2.4

INITIAL CHECKOUT

1.  Be sure the TORQUE control on the power supply is off (CCW).
2.  Turn on the speed readout device (if applicable) and the torque controller.
3.  Rotate the dynamometer shaft manually while simultaneously adjusting the TORQUE

CONTROL clockwise very slowly.

4.  Stop when you begin to feel resistance occurring on the shaft.
5.  If there is a speed reading instrument, note the speed (rpm) reading.
6.  Return the TORQUE CONTROL to zero.

Note:

With the TORQUE CONTROL off, you may notice slight torque
pulsations on the shaft. This is normal. For a further description
of “salient poles” please refer to

Section 3.8 Cogging
