High efficiency roller shade
First Claim
1. A method for controlling a motorized roller shade that includes a shade attached to a shade tube, a microcontroller and a DC gear motor disposed within the shade tube, the DC gear motor including a housing fixed to the shade tube and an output shaft coupled to a support shaft fixed to a mounting bracket, the method comprising:
- receiving a command from a remote control; and
moving the shade to a position associated with the command by energizing the DC gear motor with at least one battery located within the shade tube to rotate the shade tube and the DC gear motor housing while the DC gear motor output shaft and support shaft remain fixed.
