MAGNETIC BRAKE FOR POWERED WINDOW COVERING

Two braking magnets are attached to the housing of a motor of a motorized component such as a window covering, with one magnet north face down and the other magnet south face down. With this structure the motor is braked from turning under the weight of the window covering when deenergized, while du...

Beschreibung
Zusammenfassung:	Two braking magnets are attached to the housing of a motor of a motorized component such as a window covering, with one magnet north face down and the other magnet south face down. With this structure the motor is braked from turning under the weight of the window covering when deenergized, while during operation the average null value of the braking field results in minimal drag on the motor.
