3.8.1 Stator
The stator used is not interchangeable with any previous phase or series of machine. This stator
has 36 poles with the windings being Aluminium and is Identified by the printed marking AL 60
190T it looks the same as a copper Stator but is 19.5 per winding.
Stator (36 Poles)
Testing the Stator
If the stator needs to be tested we would first recommend testing the resistance of the windings at
the harness that is connected to the Motor Control Module. (Refer to Section 5.9).
Note: Ensure that the Rotor and bowl are stationary when measurements are made.
Testing the stator from the console
The resistance of each individual winding is approximately 19.5, however when testing the stator
from the console we are testing across two windings therefore the resistance should be
approximately. 39 +/- 10%
To test all windings you will need to measure across:

Red & Blue
 Red & Yellow
 Blue & Yellow
If the meter shows an incorrect reading we would then recommend testing the stator from
underneath the machine as there could be a fault in the wiring harness. To test the stator, remove
the rotor and stator. Refer to Sections 8.19 and 8.20.
Note: Two clamp plates are used to secure the Stator, one on each side. The four bolts are
tightened to a torque of 5-7Nm. The plastic bolt for securing the Rotor requires a 16mm
socket and should be tightened to 8-10Nm.
