Motor
WM2496H*M
The DC 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. Unlike a more
traditional brushless motor, the rotor
surrounds the stator rather than
being attached to it.
A Hall Effect sensor determines the
speed and direction of the motor.
It also can read that the load is off
balance when the drum speed
fluctuates, eliminating the ball
sensor found on previous models.
