Reluctance Motor The origin of this motor can be traced back to 1842. The Synchronous reluctance motor has a stator wounded as that of a 3-phase induction machine. It works as a synchronous motor without DC field winding in its ...
Contactor • A contactor is an electrically controlled switch (relay) used for switching an electrical power circuit.A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt ...
Introduction A poly phase induction motor consists of two major parts, the stator and rotor When stator is excited with a.c voltage, rotating field is set up This field produces an EMF in the rotor winding by mutual induction ...
