This conveyor gear drive motor replaces the BALDOR brand and can be used on most MIDDLEBY MARSHALL conveyor ovens. In 2005, MIDDLEBY changed to this style motor which is more efficient, has a larger gear box, and has the speed sensor included in the silver cap. This motor runs cooler and last longer compared to the SCR rated motor being sold elsewhere. If you are replacing this motor, you will need to purchase the conveyor control pick-up speed sensor kit (sold separately) as it is used in conjunction with this motor.
