MAX GUARD Insulation System
The patented MAX GUARD insulation system is the only insulation system which provides unlimited lead length between the drive and motor. This MAX GUARD insulation system combines a unique, low stress winding configuration and corona magnet wire for extending motor life under the adverse dielectric & thermal stresses generated by the high switching frequencies of PWM medium voltage drives. The MAX GUARD insulation system surpasses the needs of NEMA MG1, Part 31 and is a standard feature of BLACK MAX & BLUE MAX Marathon motors.
