Motor control circuits

The purpose of the field-oriented control (FOC) is therefore to create a tool that allows the decoupling control of the flux and torque-producing current components from the three-phase AC currents flowing in the coil. The FOC drive system is a system based on the principle of decoupling the above power components thanks to the stator current feedback control (the innermost circuit of the drive system). The FOC-type control method belongs to the class of vector control methods for electrical machines.

Modeling and simulation of dynamic systems is Pham Huy Hoang Electromotive force (emf) voltage (electromotance): is that which tends to cause current (actual electrons and ions) to flow, is the external work expended per unit of charge to produce an electric potential difference across two open-circuited terminals.

The control system for a star delta contactor is sequence circuit. The star contactor and delta contactor are interlocked relative to each other with a ‘either - or’ condition. Switching from ‘star’ to ‘delta’ is done automatically by means of a time relay. In the circuit above, the star contactor is energised first, then the mains contactor. Circuits in which the mains contactor is energised first, followed by the star contactor, are also common.
