OverviewPrincipleHistoryConstructionRotation reversalPower factorEfficiencySteinmetz equivalent circuit
In both induction and synchronous motors, the AC power supplied to the motor''s stator creates a magnetic field that rotates in synchronism with the AC oscillations. Whereas a synchronous motor''s rotor turns at the same rate as the stator field, an induction motor''s rotor rotates at a somewhat slower speed than the stator field. The induction motor stator''s magnetic field is therefore changin…

Motor capacitor
OverviewRun capacitorsStart capacitorsDual run capacitorsLabelingFailure modesSafety issues
Some single-phase AC electric motors require a "run capacitor" to energize the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running. Run capacitors are designed for continuous duty while the motor is powered, which is why electrolytic capacitors are avoided, and low-loss polymer capacitors are used. Run capacitors are mostly polypropylene film capacitors (historically: metallised paper capacitors) and are energized …
