摘要： An exemplary method relates to operating a door closer assembly including a closer body, a pinion rotatably mounted to the closer body, a motor including a motor shaft, and a bidirectional clutch connected between the pinion and the motor shaft. The method generally involves permitting, by the clutch, rotation of the pinion in each of a first direction and a second direction without transmitting rotation of the pinion in either direction to the motor shaft; sensing, with a sensor, a rotational position of the pinion; comparing, by a controller, the rotational position of the pinion with a desired rotational position; based upon the comparing, driving the motor to rotate the motor shaft; and by the clutch, coupling the motor shaft with the pinion in response to rotation of the motor shaft, thereby transmitting torque from the motor shaft to the pinion and urging the pinion toward the desired rotational position.
