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 rom rotating when the motor is not driving the motor drive shaft.

The present invention relates to a solar electric roller shade, including a roller shade body and a solar panel that are independent of each other. The roller shade body includes a scroll, a curtain cloth wound onto the scroll, and a speed reduction motor for driving the scroll to rotate, the solar panel is externally disposed on a back surface of the roller shade body through a fixed support member, and the solar panel is electrically connected to the speed reduction motor and a battery. In the present invention, the solar panel and the roller shade body are two separated independent structures. Once mounted and debugged, the solar panel can continuously absorb light energy and provide electric energy for the electric roller shade under sufficient sunlight, and the solar panel is mounted on the back surface of the roller shade body without occupying a special erection space.

The system may include a motor releasably connected to a control module and the control module releasably connected to a drive module. The system may further include a joint releasably connecting the control module to the drive module, wherein the joint includes a floating gear. The method may include determining a motor shaft rotation of a motor shaft in a motor, determining a shade tube rotation of a shade tube that moves a window shade over a path, comparing the motor shaft rotation to the shade tube rotation, determining, based on the comparing, that the shade tube rotation is not equal to the motor shaft rotation and determining that an obstacle exists in the path of the window shade. The method may also include determining a change in at least one of current or torque in the motor.

A shading device comprises a power supply device comprising a battery, a first and a second electrical connection elements and a resilient element. The battery is disposed at a holding device for holding the screen. The first element is disposed at a load bar or the screen and configured so as to be electrically connected to an external electrical supply source. The second element is disposed at the holding device and configured to cooperate with the first element. The resilient element is configured to be fixed on the load bar or on the screen. The first element is integral with the resilient element. Furthermore, the resilient element is configured to compensate a misalignment of the first electrical connection element with respect to the second electrical connection element, when the screen reaches a position for recharging the battery.
