Reuland variable speed, inverter duty motors are available in both open loop and closed loop designs.
Series 100 and Phasor2000 styles are designed and manufactured for the most demanding applications.
Closed loop designs will handle up to 1000:1 constant torque requirements and full torque at zero speed.
Reuland's unique slot designs minimize the heating and noise effects induced by drive switching frequencies (harmonics) and eliminate typical cogging at low frequency operation.
Variable speed designs are also available with wide constant power ranges often required in machine tool spindle applications. Variable speed motors are available from fractional horsepower through several hundred horsepower in open, enclosed and blower cooled enclosures, continuous or intermittent duty.
Use of variable speed motors spans a multitude of applications. Machine tools, material handling, pumps, fans and elevators, to name a few.
