Motor Assembly - GE Profile Harmony WPGT9360 Technical Service Manual

Motor Assembly

• The washer has a direct-drive pulse-width
modulation motor that does not utilize a belt,
transmission, or mechanical brake.
• The motor assembly is composed of a coil-
wound stator, Hall sensor, and permanent-
magnet rotor.
• The motor speed and torque varies when the
pulse width modulated voltage from the inverter
changes frequency.
• The motor turns in the opposite direction when
the inverter reverses electrical polarity to the
motor.
The washer motor has an approximate resistance
value of 8 Ω between any two of the three wires:
Blue to red - 8 Ω
•
Red to yellow - 8 Ω
•
Blue to yellow - 8 Ω
•
Resistance can be measured at the yellow, 3-pin
connector on the inverter board or at the motor. (See
Inverter and Main Board Pin Connectors.
