Features

  • These 2000:1 inverter motors are operated at 1/2000 of the base speed, offering constant torque performance without overheating the system.
  • They feature a MAX GUARD insulation system that protects the motor from excessive thermal and dielectric stresses caused by the high switching frequencies of PWM drives.
  • These units are integrated with a patented fracket design for easy installation of encoders, brakes and blowers.
  • They feature a BCP bearing protection system that mitigates bearing currents caused by the inverter, thereby increasing bearing life.
  • The precision balanced design dampens vibration and increases motor life.
  • These units are available in TENV, TEBC and TEFC enclosures for maximum safety against moisture and contaminants.

Standards and Approvals

  • UL
  • CSA
  • CE

Frequently Asked Questions

What is the difference between closed-loop and open-loop vector controls?

  • Open-loop vector controls offer high starting torque and increased low-speed torque. They are ideal for applications requiring 100% of the rated torque at low speeds, like AC synchronous and induction motors.
  • Closed-loop vector controls allow 200% of the motor's rated torque at 0 RPM and are ideal for applications requiring load at standstill, like cranes and hoists.

What are these motors made of?

These Blue Max motors and mounting brackets are made of cast iron for corrosion resistance and minimal vibrations in harsh & dusty environments.

What are bearings used for?

Bearings are designed to reduce friction / stress between moving parts while supporting rotational or linear motion.
