Abstract
A powered panel moving system includes a motor, electronic drive circuitry, mechanics, a coupler, and electronic anti-entrapment circuitry. The drive circuitry drives a rotor of the motor such that the rotor has a rotational output in response to being driven. The mechanics moves a panel upon being driven. The coupler couples the rotational output of the rotor to the mechanics in order drive the mechanics for the mechanics to move the panel. The anti-entrapment circuitry controls the drive circuitry to prevent the panel from entrapping an object. The drive circuitry drives the motor based on measurements indicative of at least one of motor current, motor speed, and panel position. The drive circuitry and the anti-entrapment circuitry are integrated with one another such that the anti-entrapment circuitry controls the drive circuitry based on the same measurements.
