Blue Max Inverter Duty Brake Motors

230/460 VAC | 1 HP - 20 HP | 2000:1 Constant Torque

Marathon has a developed a reputation for conservative motor designs and highly engineered products used in a vast array of commercial and industrial applications around the world. The Blue Max three phase motor series is designed for VFD or vector applications requiring full rated torque at zero speed using closed- or open-loop controls. BlueMaxBrake The MAX GUARD® Class F insulation system delivers long, dependable motor life under the adverse thermal and dielectric stresses imposed by the high switching frequencies associated with PWM drives. In addition, the internally mounted Bearing Current Protection (BCP) system mitigates inverter sourced bearing currents, increasing bearing life. Blue Max 2000 brake motors deliver reliability in harsh environments and are performance matched to all leading brands of PWM drives to provide years of trouble-free operation.
They are designed for vector applications where up to a 2000:1 constant torque speed range is required. These motors are ideal for use on conveyors, machine tools, cranes, hoists, and other industrial machinery requiring quick stop and/or holding torque.
