Synchronous Motors: Applications And Working Principle
Electrical motors are an electro-mechanical device that converts electrical energy to mechanical energy. Based on the type of input we have classified it into single phase and 3 phase motors. The most common type of 3 phase motors is synchronous motors and induction motors.When three-phase electric conductors are placed in certain geometrical positions (i.e. …

Optimal vector control for wound rotor salient pole synchronous motor …
Abstract: This contribution introduces an optimal control for wounded rotor salient pole synchronous motor intended for a new mining machine drive. The optimum considers demand for maximum torque of the motor. Hence the main idea is to find optimal values of stator flux current I sd and rotor field excitation current I f to achieve maximum available torque of the machine.
