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.
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 Hazard Duty 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 industrial applications with vector drives where up to a 2000:1 constant torque speed range and/or precise speed or torque regulation is required, including positioning equipment. Used in dirty, dusty or caustic environments where cast iron construction is required, and installed in hazardous environments as defined by the motor’s explosion proof class and group rating. Consult the National Electrical Code and your local regulations for the proper selection of motors in hazardous locations.
