DIRECT DRIVE MOTOR
The motor is a direct-drive, brushless,
DC motor. It is attached to the drum via
a splined shaft, eliminating belts,
pulleys, transmissions, and the
inherent problems associated with
them. The rotor is attached to the shaft
by one large bolt.
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.
