Motor and Drive System
The new Profile washer incorporates 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. Voltage given is for information only. The motor is bidirectional, constantly reversing it’s direction to
provide agitation. The motor is connected by a belt to the shaft and mode shifter assembly. By energizing
or de-energizing a coil, the mode shifter assembly engages or disengages the shaft and tube. This allows for
agitation and spin cycle modes.
Motor status is displayed through a series of flash codes from a green LED located on the front side of the
inverter just above the motor. These codes are stored in memory until cleared.
