Inverter; Motor - GE WSSH300G Technical Service Manual

Inverter:

The inverter is mounted to the bottom plate of the washer
in the left rear corner of the washer. The inverter controls
the following operations:
Note: The control board assembly is the board
that is mounted in the console, and the inverter
is in the left rear corner of the washer.
1. The speed of the drive motor by converting input
line to neutral single phase 60 Hertz voltage, to a
varying frequency, three phase output voltage from
zero to 300 VAC. By varying the amount,
frequency, and polarity of the voltage and
comparing the input from the tachogenerator on
the drive motor, the speed control board can
operate the drive motor at a preprogrammed speed
and direction.
2. The balance of the load in the washer during the
spin cycle by converting the sine wave from the
tachogenerator to square waves and comparing the
distance between the square waves.

Motor:

The motor is mounted to the bottom of the outer tub.
The motor is an induction, three phase AC motor that
varies speeds when the voltage from the speed control
board varies in frequency and amount. The motor has a
tachogenerator that inputs the speed of the motor to the
speed control board.
