Because of this, the start windings must use larger wire than that used for the split-phase or capacitor-start motors. The capacitor used during the run cycle may be the same one used to start the motor, or it may be a different, smaller capacitor.
Winding capacitance is the intrinsic capacitive coupling between coils or turns in electrical systems, resulting from insulating materials and conductive parts. Accurate measurement of winding capacitance is crucial for maximizing device performance and ensuring secure operation in transformers, motors, and generators.
A capacitor is wired in series with this coil and it has the effect of causing a shift in the phase of the current in the auxiliary winding relative to that of the main winding. The result is that the magnetic field in one winding leads the other and this imparts enough rotational force into the rotor to: get it to start.
Run capacitor C 1 and auxiliary winding can be designed in such a way that they provide balanced two-phase field. The balanced two-phase field avoids the backward rotating field and improves the power factor and efficiency of the motor. The torque-speed characteristics of two-value capacitor run motor are shown in figure (2).
A capacitor motor is a single-phase induction motor with a main winding arranged for a direct connection to a source of power and an auxiliary winding connected in series with a capacitor. You might find these chapters and articles relevant to this topic. Charles J. Fraser, in Mechanical Engineer's Reference Book (Twelfth Edition), 1994
