Three-phase motors are more efficient than single phase motors and are commonly found in applications requiring more than 7.5 horsepower. Although the National Electric Code does not specify specific conductor colors for three-phase current, it is common to use black, red and blue wires to identify lines L1, L2 and L3 respectively.

If you are wondering about the difference between 3 phase vs single phase AC motors, just remember this. Single phase AC motors usually operate on a single phase source of power while 3 phase AC motors operate on a three phase source of power.

The polyphase induction motor invented by Nikola Tesla in 1886 had been developed by 1895 virtually into its present squirrel-cage form. The slip-ring induction motor was developed a short time later.

Three phase induction motors have a very simple construction composed of a stator covered with electromagnets, and a rotor composed of conductors shorted at each end, arranged as a "squirrel cage".

This motor comes with a (detached) cord with grounded plug, motor capacitor and a 3-speed control switch. All of the wiring between your electric motor, capacitor and quickness control switch is still hooked up however the cord itself is normally detached as seen in the photos.

Farm equipment tends to be fairly power-hungry, so your best bet is to go with a high-horsepower model. The greater the HP rating, the more intense of a load the motor can handle.
