Short title: Capasitor-start single-phase motor circuit diagram: Image title: A circuit diagram of a motor with LC circuit with capacitor embedded. Source: Energy-Efficient Electric Motors, Revised and Expanded, Ali Emadi, October 3, 2018, ISBN: 9781351836678
English: Diagram of revolving-field single phase generator with two poles. As the rotor turns, the lines of force at two poles are cut by the coils inducing current. The output from two coils are "in phase". The direction of current changes to the opposite site every 180 degrees of rotation.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...
In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...

Because the voltage of a single phase system reaches a peak value twice in each cycle, the instantaneous power is not constant. Standard frequencies of single-phase power systems are either 50 or 60 Hz. Special single-phase traction power networks may operate at 16.67 Hz or other frequencies to power electric railways. [1]
