Inverter Duty Motors

Inverter Duty Motors

Kor-Pak provides high-performance Inverter Duty Motors to work in conjunction with your Variable Frequency Drives.  AC motors can be driven by across-the-line contactors and starters. The electricity sent to the motor is a very clean (true) sine wave at 60Hz. Noise and voltage peaks are relatively small. However, there are drawbacks: the motors can only run electrically at one speed (speed reduction is usually handled by gearboxes or some other, usually inefficient, mechanical means) and the inrush of electrical current (when the motor is first turned on) is usually 5 to 6 times the normal current that the motor consumes. The speed reduction apparatus is expensive and bulky, and the inrush can wreak havoc with power systems and loading (imagine an air conditioning system in an old house – when the compressor kicks on, the lights dim; now imagine the same circumstances with a motor the size of a small car).

Features and Benefits of Inverter Duty MotorsBLUEMAX_1

The modular design of our motors consists of a foot mounted NEMA motor, and a “C” face drive end and accessory “C” face. This design feature shortens delivery time and can be furnished with a variety of options, including encoders and brakes. Capable of a 1000:1 speed range.

Features

  • 1/2 to 50 hp
  • Suitable for CMAA Class A through E
  • 1.0 service factor on PWM drive
  • Totally Enclosed Non Ventilated (TENV)
  • NEMA Design A, optimized for operation with IGBT inverters
  • Class F insulation, with a patented Max Guard winding system for use with IGBT variable frequency drives
  • Class F thermostats (Klixons) in all three phases
  • Modular design with C-Face end bells for maximum flexibility and quick delivery
  • Voltage 230/460, 3 phase, 60Hz
  • Optional brakes and encoders
  • Two year warranty
