    摘要: A motorized shade control system is described in which electrostatic charges, generated by a shade fabric being reeled on to and off of a roller are conducted to and grounded by the shaft of a remote drive motor. The drive motor is ultraquiet, and includes a worm gear drive and single-stage reduction gear assembly which delivers about 0.010 to 0.005 horsepower, with motor output shaft rotational velocity limited to no more than about 30RPM. The motor is mounted within a two-part housing and is clamped between elastomeric acoustic dampers connected between pedestals extending from opposite interior wall surfaces to opposite sides of the motor. An H-bridge drive circuit powers the motor under the control of a microprocessor which can be addressed by an infrared remote transmitter or by a wall mount control. Soft start and soft stop circuits are employed to further reduce noise.
