Patent

CA 2060299

Abstract of the Disclosure A motor controller for reversibly driving a member to be driven along a predetermined path of travel is capable of sensing the rate of speed of the member to be driven and to compare with a predetermined speed level and to adjust the motor drive until the rate of advancement of the driven member corresponds with the predetermined speed level. The motor drive means is completely deactivated if the actual speed should not reach a predetermined start-up threshold within a selected time interval after the motor is initially turned on or should drop beneath the stay-on threshold level which is set beneath the desired speed. The motor drive can also be regulated to run at different reduced or normal speed settings depending upon its intended application.
