The rotating magnetic fields

The rotating magnetic fields are a consequence of the movement around the rotor of an induction electric motor 7.5 horsepower 213TC frame. In other parts of the engine, the magnetic fields are generally weaker than in the air gap and so are neglected when analyzing the behavior of the engines. The rotational speed of the […]

Electrical Induction Machines

The polyphase stator winding connected to a polyphase source establishes a magnetic field distribution which rotates relative to this winding with synchronous speed ωs which will depend on the frequency f1 of the polyphase source and the number of pairs of poles p from that same winding. The electric frequency of the induced voltages and […]
