Recent Trends in Electric Machines: Recent Trends in Electric Machines are neural networks, Artificial Intelligence, expert system, fibre communications and integrated electronics, hot superconductors and other new ceramic conducting and dielectric…
Types of Rotating Electric Machine: The Types of Rotating Electric Machine are namely the dc machine, the polyphase synchronous machine (ac), and the polyphase induction machine (ac). Three materials are…
Starting of Synchronous Motor and Precautions: As already stated the synchronous motor has got no self starting torque and the motor must first be brought up to synchronous speed by…
Starting of Electric Drives: The most important processes associated with controlled electric drives are (i) starting, (ii) speed control (iii) braking, (iv) reversal of direction of rotation. All these are…
Three Phase AC Series Commutator Motor: This machine has a 3-phase stator winding similar to that of an ordinary induction motor and may be wound for high voltage if required.…
Protective Devices and Interlocks: Protective devices must be incorporated in the control circuit (or circuits) to interrupt the flow of current to the motor to guard against overloads or other…
Amplidyne (Rotary Amplifier) - Definition, Construction, Connection Diagram, Workings and Applications: The amplidyne is a rotary amplifier in which a small amount of power supplied to excite the field is…
What is Metadyne Control? - Construction, Working and Applications: The metadyne control system is based on constant current system of speed control. In resistance control or series- parallel control a…
