2.7 Motor
2.7.1 Stator
This stator used on the Phase 7 machines are unique to this phase only and therefore it is
not
interchangeable
with any previous phase or series of machines. The stator has 36 poles instead
of 42 poles, and the pole tips are curved. The resistance of the windings remains the same as for
the Phase 5, Series 9, and Phase 6, Series 11 and 12 machines at 16
W
per winding. The rotor
position sensor is also unique to this stator. (Refer to Section 2.7.3.)

Testing the Stator
If the stator needs to be tested we would first recommend testing the resistance of the windings
from the harness that is connected to the Motor Control Module. (Refer to Section 7).
Note: Ensure that the Rotor or basket is stationary when measurements are made.
Testing the stator from the console
The resistance of each individual winding is approximately 16
W
, however when testing the stator
from the console we are testing across two windings therefore the resistance should be approx.
32
W
+/- 10%.
To test all windings you will need to measure across:
·
Red & Blue
·
Red & Yellow

Blue & Yellow
