Remove 4 Motor Nuts
Motor
WARNING:
• The motor is not grounded. Unplug the unit before servicing to avoid electric shock.
• Motor temperature may reach 176 °F. Use care to avoid severe burns.
Note:
• The motor is mounted on 4 ceramic insulators that insulate the motor from cabinet ground.
• The pulley has a ceramic insert to insulate the motor from cabinet ground, should the belt get wet.
The drive motor is a reversing, permanent magnet, 3-phase 230 VAC motor that varies speed and
torque when the pulse width modulated voltage from the inverter changes frequency or amount. The
motor reverses rotational direction when the inverter reverses electrical polarity to the motor.
The motor has an internal tachogenerator which produces voltage when the motor shaft is rotated. This
voltage is monitored by the inverter to determine motor speed. The inverter makes speed adjustments
as necessary, based on this information.
The inverter adjusts motor torque as necessary to start the motor; therefore, a clutch is not required. A
45-second ramp-up time can be expected at the start of agitate or spin.
Note: Terminals 1, 2, and 3 (at connector CN10) are the motor windings. Proper resistance for a cold
motor is 6 Ω +/- 10% between any 2 of the 3 terminals.
To remove the motor:
1. Remove the front panel (see Front Panel).
2. Remove 4 (3/8-in.) nuts from the bottom of
the motor.
3. Move the motor toward the transmission and
remove the belt.
4. Rotate the transmission to give the motor
clearance. Tilt the top of the motor toward the
transmission. Remove the motor.
Note: Proper belt tension is 1/2-in. deflection at
midpoint between pulleys.
