    • A battery-powered load control device (e.g., a motorized window treatment) is able to supply a pulse-width modulated current to an electrical load (e.g., a motor) while conducting a substantially DC battery current from a battery powering the motorized window treatment. The motorized window treatment includes a motor drive circuit for driving the motor with a pulse-width modulated signal to adjust the rotational speed of the motor, such that the motor conducts the pulse-with modulated current. The motorized window treatment also has an input circuit coupled between the battery and the H-bridge drive circuit. The input circuit has an output for conducting the pulse-width modulated load current, and conducts the substantially DC battery current from the battery. The input circuit may comprise, for example, a passive filter circuit (such as an inductor-capacitor filter) or an active circuit (such as a power converter).

    • A motor drive unit assembly for a motorized drapery system having a drapery fabric can include a motor having a drive shaft, an output member rotatable about a drive axis, such that rotation of the output member about the drive axis causes the drapery fabric to move, and a clutch member operatively coupled between the drive shaft of the motor and the output member. The clutch member is configured to automatically couple the output member to the drive shaft such that rotation of the motor drive shaft causes the output member to rotate about the drive axis when the motor drives the drive shaft. The clutch member is further configured to automatically decouple the output member from the motor drive shaft so that the output member rotates about the drive axis relative to the motor drive shaft when the output member is manually driven.
    • 具有帷幔织物的电动帷幔系统的电机驱动单元组件可以包括具有驱动轴的电机,可绕驱动轴线旋转的输出构件,使得输出构件围绕驱动轴线的旋转导致帷幔织物移动, 以及可操作地联接在马达的驱动轴和输出构件之间的离合器构件。 离合器构件被配置为将输出构件自动地联接到驱动轴,使得当马达驱动驱动轴时,马达驱动轴的旋转使得输出构件围绕驱动轴线旋转。 离合器构件还被构造成使得输出构件与马达驱动轴自动地分离,使得当手动驱动输出构件时,输出构件相对于马达驱动轴围绕驱动轴线旋转。
