Abstract
A belt drive system for an internal combustion engine rotatably coupled to a rotary motor is provided. The internal combustion engine includes at least three cylinders each having a piston operable to turn a crankshaft. The belt drive system includes a belt and a controller. The belt is coupled to crankshaft of the internal combustion engine and the rotary motor; and the controller is operatively connected to the rotary motor, wherein the controller causes data processing hardware to perform the following operations: apply a torque to the rotary motor; and change the torque of the rotary motor prior to a change in a rotary speed of the internal combustion engine to maintain a predetermined tension in the belt and reduce a rotary motor torsional response through the belt drive to the torsional vibration input from the internal combustion engine.
