REMOVAL
The motor is an integral component of the transaxle
assembly. Refer to the Transaxle section for information.
This section is one section of a complete service
manual. Before starting any procedure, read all
warnings and instructions that are located in the
Service Guidelines chapter.
WARNING
INSPECTION
Refer to the table at the end of this section for service
limits and specifications.
Phase Windings
The diagram shows a simplified schematic of a 3-phase
AC motor.
Static testing of the motor consists of checking the
resistance of the phase windings. Failure of any of the
phase windings typically results in a significant deviation
of the normal resistance of the windings or a short to the
motor frame.
The internal junction of the windings is not accessible so
all tests will be testing two windings in series.
A milliohm meter is required to test the phase winding
resistance.
Test the resistance across the 3 phases as follows:
U:V
U:W
V:W
All three test results should be within the service limit.
Test the resistance from all three terminals to the frame
of the motor. All should be an open circuit.
If the motor fails any test, then the motor should be
replaced.
Thermal Sensor
The thermal sensor is a temperature sensitive resistor.
The sensor is buried deep within the phase windings.
Testing the thermal sensor consists of checking the
resistance.
The tested resistance of the thermal sensor will vary
depending on the current temperature of the sensor. In
most cases, failure of the thermal sensor will result in a
significant deviation of the resistance.
