Abstract
A motor drive unit may include a motor and a magnetic brake. The motor may be configured to be located within a motor drive unit housing of the motor drive unit. The motor may include a motor drive shaft defining a motor drive shaft rotational axis in a longitudinal direction. The motor drive shaft may be configured to rotate a roller tube of a motorized window treatment. The magnetic brake may include a stationary portion that includes a first plurality of magnets and a rotating portion that includes a second plurality of magnets. The first plurality of magnets may be configured to repel the second plurality of magnets such that repulsion between the first plurality of magnets and the second plurality of magnets generates a holding torque to prevent the motor drive shaft from rotating when the motor is not driving the motor drive shaft.
