Summary: Single-phase induction motors. Single-phase induction motors are not self-starting without an auxiliary stator winding driven by an out of phase current of near 90 o. Once started the auxiliary winding is optional. The auxiliary winding of a permanent-split capacitor motor has a capacitor in series with it during starting and running.

For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by

A 120-V, 60-Hz, capacitor-run, two-pole, single-phase induction motor has the following parameters: L main = 41.1 mH Rmain 0.331 12 Laux = 89 mH Raux = 1.55 S2 Lr = 2.04 uH R, = 15.0 μΩ L main,r = 0.30 mH Laux.r = 0.461 mH You may assume that the motor has 48 W of core loss and 23 W of rotational losses. The motor windings are connected with ...
Shaded Pole Motors. One specific type of single-phase motor, the shaded pole motor, cannot be easily reversed. The construction of shaded pole motors is lopsided and generates a lopsided magnetic field, meaning the motor favors turning in a specific direction. This eliminates the capacitor and provides a uniquely direction-specific construction.
Single-phase motors are widely used in household applications. Shaded-pole and split-phase capacitor-start single-phase induction motors are very popular for their ruggedness and their comparatively low cost. Recently, line-start single-phase motors are gaining market shares. However, their superior efficiency and torque density are …
Without a capacitor, a single-phase capacitor start induction motor can not run. The other single-phase induction motors, such as shaded pole and reluctant type do not require capacitor for their starting. In this article, we will discuss how the capacitor helps in producing the starting torque in a capacitor start single-phase motor.
