Regarding the basic operation of Induction motor and its working principle from first principle.
Winding (stator and rotor), production of rotating flux and rotation of rotor.
A 12 pole, 60 Hz synchronous machine has an internal rms voltage of 10 kV. Its internal synchronous reactance is 10 ohms. The machine is connected to a network with a terminal voltage of 11 kV rms. The phase angle difference between the internal and external voltages is 30 degrees (internal minus external). (a) Is this machi ...continues
A 50 Hz induction motor operates in such a way that the slip is 1.45. (a) is this motoring, generating or braking? Explain (b) If the synchronous speed is 900 rpm, find the mechanical speed. (c) Find the number of poles. (d) Find the frequency of the rotor currents. (e) Find the speed of rotation of the magnetic field in th ...continues
Basics problems of Induction motor
