LEESON Brake Motors, Three Phase, Totally Enclosed, C Face Footless
Marathon brake motors are intended for conveyors, packaging machinery, machine tools, hoists, elevators and door operators. These three-phase motors are more efficient and have a higher starting torque as compared to their single-phase counterparts. They do not require a capacitor, start windin...g, centrifugal switch, or any other type of starting device that can wear out and fail. They are ideal for applications requiring quick stopping and holding action.Read more
