    • A motorized window shade system (30) is described in which electrostatic charges, generated by a shade fabric (54) being reeled on to and off a roller (52) are conducted to and grounded by a shaft (66) of a roller drive motor (100). The drive motor (100) is ultraquiet, and includes a worm gear drive and a single-stage reduction gear assembly (230) which delivers about 0.010 to 0.005 horsepower, with the motor shaft rotational velocity limited to no more than about 30 RPM. The motor (100) is mounted within a two-part housing (102, 220) and is clamped between elastomeric acoustic dampers (240, 241) connected between pedestals (230, 231) extending from opposite interior wall surfaces to opposite sides of the motor (100). An H-bridge drive circuit (301) powers the motor (100) 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 operation implemented by means of a computer program is employed to further reduce noise.
    • 描述了一种电动窗帘系统(30),其中通过卷绕在和离开辊(52)的帘布(54)产生的静电荷通过辊驱动电机的轴(66)被传导和接地 (100)。 驱动马达(100)是超静音的,并且包括蜗轮传动装置和单级减速齿轮组件(230),其传递大约0.010至0.005马力,马达轴旋转速度限制在不超过约30RPM。 电动机(100)安装在两部分壳体(102,220)内并且被夹持在连接在从相对的内壁表面延伸到电动机的相对侧的基座(230,231)之间的弹性隔音器(240,241)之间 (100)。 H桥驱动电路(301)在微处理器的控制下对电动机(100)供电,该微处理器可由红外遥控发射器或壁挂式控制器寻址。 采用通过计算机程序实现的软启动和软停止操作来进一步降低噪声。
