This short video shows How To Choose An Electric Motor for your air compressor.
It's easy to find the motor you need.
1) What is the HP?
2) What is the frame or FR (Frame) size? (If it ends in "Y", call first as this means something is different about your mounting bracket).
3) What is the RPM?
4) What voltage 110 V, 220 V, etc?
5) What is the Phase (Single Phase or 3 Phase)?
6) What is the shaft diameter?
All of this info is on your old motor.
All motors are C.W. rotation (shaft away from you) and open style unless otherwise noted. If 110,115,120 Volts, order a 115V motor. If 200 or 208 Volts order a 200-208V motor. If 220, 230, 240 Volts order a 230V motor.
