Variable Speed Motors

Industrial electric motors from Baldor are available for most general purpose applications and processes. However, some AC Variable Speed applications require constant torque at zero speed. Large AC Variable Speed Motors are designed as standard to meet a class F temperature rise at 1.0 SF. In order to produce a motor which is capable of full life expectancy while powered by an inverter wave form there are certain features that must be included in all Large AC Variable Speed Motors.

Features

The minimum feature set to be included on all Variable Speed Motors includes:
  • 3.5pu Surge Withstand
  • Qty (2) Insulated Bearings
  • Shaft Grounding Device
  • Class II Shaft Material

Common Applications

  • Winders
  • Positioning & Extruders
  • Web Processing
  • Oil Drilling & Induction Servo
  • Spindle
