Rotor Current Frequency In Induction Motor. You mean rotor frequency in an induction motor. Typical Induction Motor Rotors The magnetic field generated in the stator induces an EMF in the rotor bars. It is the frequency of alternating current flowing in rotor winding. A a stator and b a rotor.
And rotor frequency gets lesser than supply frequency. The speed of the rotor during starting condition is zero therefore the relative speed between stator rotating magnetic field and rotor speed is Ns N Ns When the rotor conductors cut the rotating magnetic field an emf will be induced in it. Rotor frequency slip supply frequency. In a high frequency induction motor EMF is induced leading to current flow. Rotor as the name suggests it is a rotating part of an electrical machine in which current is induced by transformer action from rotating magnetic field. But when the rotor starts revolving then the frequency depends upon the relative speed or on slip- speed.
The speed of the induction motor is.
F s slip f supply frequency. The speed of the rotor during starting condition is zero therefore the relative speed between stator rotating magnetic field and rotor speed is Ns N Ns When the rotor conductors cut the rotating magnetic field an emf will be induced in it. In a high frequency induction motor EMF is induced leading to current flow. If the operating speed is zero Ns N and the frequency of the rotor current is. F source frequency in Hz. Typical Induction Motor Rotors The magnetic field generated in the stator induces an EMF in the rotor bars.
