Package Includes: AC Commutator Motors | AC Motors - All About Circuits AC commutator motors may be either single-phase or poly-phase. The single-phase AC version suffers a double line frequency torque pulsation, not present in the polyphase motor. Since a commutator motor can operate at a much higher speed than an induction motor, it can output more power than a similar size induction motor. Types of Single Phase Induction Motors | Single Phase ... Capacitor start capacitor run induction motors are single phase induction motors that have a capacitor in the start winding and in the run winding as shown in figure 12 and 13 (wiring diagram). This type of motor is designed to provide strong starting torque and strong running for applications such as large water pumps. Induction motor - Wikipedia An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type.
