Abstract

See full text

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.
