Page 5: Motor And Drive System
Motor and Drive System The new GE washers incorporate a new motor and drive system. The 120 VAC input powers a three phase induction inverter/motor assembly. The inverter produces approximately 340 VDC, which is pulse width modulated (PWM) to control motor speed. There is no location to check inverter output voltage to the motor. -
Page 6: Shaft And Mode Shifter Overview
Shaft and Mode Shifter Overview The shaft and mode shifter assembly consists of the shaft and tube, mode shifter cam, and mode shifter coil. It operates in 2 distinct modes, spin and agitation. The shaft and tube transfers power to the wash system. Motor power is transmitted to the shaft and tube from the drive belt to the drive pulley. - Page 7 Shaft and Mode Shifter Assembly Mode Shifter Coil Mode Shifter Cam Drive Shaft Agitate Position Mode Shifter Coil Mode Shifter Drive Pulley Note: Mode shifter coil energized for agitate mode; cam teeth disengaged from drive pulley. Spin/Idle Position Mode Shifter Coil Mode Shifter Drive Pulley...
- Page 8 Mode Shifter Operation - Agitation The mode shifter is controlled by the motor inverter circuit. When the washer starts the agitation cycle, the inverter energizes the mode shifter coil. The magnetic field of the coil lifts the mode shifter cam, disengaging it from the drive pulley.
