Zusammenfassung:	A mechanism for opening and closing an overhead door includes a drive loop coupled to the overhead door, a motor with a drive shaft and a drive wheel for driving the drive loop. A one-way bearing couples the drive shaft to the drive wheel, which one-way bearing is configured to transmit torque from the motor to the drive wheel, as the motor rotates the drive shaft in a first rotational direction to raise the overhead door, and configured so that torque is not transmitted to the drive wheel as the motor rotates the drive shaft in a second rotational direction opposite the first rotational direction. As a result, the motor applies torque through the one-way bearing to raise the overhead door and to support the weight of the overhead door while lowering the overhead door.
