For our customers who wish to control the speed of their DC motor with an AC supply, Motor Technology, Inc. offers a user-friendly speed control. The Model 700A100 speed control is a compact and exceptionally dependable control that allows you to maintain motor speeds as close as ±2% over the full range of the motor performance or as low as ±1% over the mid-range of the motor performance.
By simply adjusting the control knob of the potentiometer, motor speeds can be adjusted from 200 - 22,000 rpm and gearmotors can approach speeds as low as 0.005 rpm, depending on the motor model and the gearbox reduction ratio. For customers who don't have a DC power supply and yet like the advantages of the variable speed control on DC motors, the Model 700A00 control is an excellent choice.
For information on which 700A100 control to use in your application, please consult the DC Motor Control Selection Process & Wiring Schematic page.
