MotorsQuestion 226 of 1506

A small bench grinder with an easily started load needs a single-phase motor of about 1/3 horsepower and no capacitor. Which type fits?

  1. A capacitor-run motor
  2. A resistance split-phase motor
  3. A synchronous reluctance motor
  4. A wound rotor motor
Show answer

Correct answer: A resistance split-phase motor

The simple resistance split-phase design serves well up to about 1/3 hp for easily started loads.
