Abstract: A motorized roller tube for reeling and unreeling a flexible member between fully open and fully closed conditions operates with minimized sound level. A variable controller energizes a motor with a controllable RPM driving a gear reduction assembly. The motor has a speed versus torque characteristic which extends linearly from a high maximum RPM and low minimum torque, to a low minimum RPM and high maximum torque, and having a peak efficiency at a given RPM. The motor moves the flexible member between its fully open and fully closed positions at a motor speed less than the given peak efficiency RPM and less than 50% of its high maximum RPM, and at a motor efficiency which is less than 25% of the peak efficiency whereby the motor is intentionally operated in a high torque and low efficiency manner.

Abstract translation: 用于在完全打开和完全关闭状态下卷绕和松开柔性构件的电动滚筒管以最小的声级进行操作。 可变控制器通过驱动齿轮减速组件的可控RPM来激励电动机。 电机具有从高最大转速和低最小扭矩线性延伸到低最小转速和高最大转矩线性的转速与转矩特性，并在给定转速下具有峰值效率。 马达使柔性构件在其完全打开和完全关闭位置之间以低于给定峰值效率RPM的电动机速度移动，并且小于其最大RPM的50％，并且在马达效率小于峰值的25％ 电动机有效地以高扭矩和低效率的方式操作的效率。
