split-phase motor



  • (written as split phase motor)
    An induction motor that typically has two windings, a main and an auxiliary. While noisier, more expensive, and harder to start than three-phase motors, single-phase motors are excellent for medium duty applications and where stops and starts are somewhat frequent.


  • A motor which has an auxiliary winding connected with the main winding when starting, and which after reaching a specified speed runs utilizing only the main winding. Used, for instance, where neither high cycle rates nor high torques are required, as in the case of small blowers.
