9-3. STATOR ASSEMBLY Wiring Circuit in the MAIN PWB / Wiring Diagram diagram MAIN PWB NA1NA MICOM Function The DD motor can be driven from stopped to maximum speed in infinite steps in either direction. There are 36 poles on the stator; 12 permanent magnets spaced around the rotor. There are no brushes to wear out. - Page 35 The hall sensor determines the speed and direction of the motor. It also can read that the load is off balance when the drum speed fluctuates. Test point - Voltage Testing Hall Sensor at Stator Result (Hall Sensor) (2) (4) (1) (3) (5) If measuring voltage from the Main PCB Assembly to the Hall Sensor, use the following steps:...
- Page 36 7. To measure output signal voltage from the hall sensor, carefully move test leads to terminals 1 to 4, blue and gray. Slowly rotate motor rotor by hand. You should read a pulsing 10 Vdc. If 10 Vdc is measured from 1 to 4, move lead on blue wire to red wire, terminal 2.
