Does the motor cycle on and off, such as in a cycling piston air compressor?


Does the motor run continuously while the compressor loads and unloads the motor, such as in a rotary screw air compressor?


Please provide application and nameplate information for the three-phase motor.
If the compressor uses a paralleled three-phase motor,
then put motor #2 nameplate info in the second line, below.

Ronk will assume the compressor motor starter will be a standard across-the-line starter with thermal overloads. If the compressor motor starter uses any three-phase electronics, such as a voltage monitor, current monitor or frequency drive (VFD), further information will be required. Please call our Sales Department at 800-221-7665 to discuss options.
