Washer Motor and Drive System Overview

The new GE laundry center washer incorporates a new motor and drive system. The motor is a variable
speed bidirectional motor, with rpm feedback to the main board from an internal Hall sensor. Motor power is
transmitted to the drive pulley by a drive belt. The drive pulley is attached to 1 end of the agitator shaft and
the agitator is attached to the other. The spin tube is fi xed to the washer basket at all times. The transmission
mode of operation is controlled by a thermoactuator, commonly referred to as a wax motor. The wax motor
controls a spring-loaded actuator fork that determines if the transmission will be in the agitate or spin mode
of operation. In agitation mode, the spin tube is fi xed to the platform and the agitator shaft rotates freely. In
spin mode, the agitator shaft is fi xed to the tube and both rotate together.
