Inductance of spinning induction motor
Web24 feb. 2012 · An induction motor (also known as an asynchronous motor) is a commonly used AC electric motor. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. WebThe regulation system for the high equality induction motor speed applications are guaranteed by the precious speed closed-loop control. If the speed encoder, rotary …

WebElectromagnetic induction occurs whenever the magnetic field through a conductor changes. This can be due to a conductor moving through a magnetic field or a conductor being in a fixed position within a changing magnetic field, such as that due to an alternating current. Both of these result in an e.m.f. being induced in the conductor. Web1 dag geleden · In induction motors, the stator’s rotating EMF induces an opposing EMF in the rotor wires, causing it to spin (via Faraday’s Law & Lenz’s Law). Induction motors are often called “asynchronous” motors because their rotational frequency is always lower than the AC frequency.

WebThe reactance of the induction motor depends upon the inductance of the rotor and the frequency of the voltage and current in the rotor. If L 2 is the inductance of the rotor, the rotor reactance is given by the equation shown below: But, as we know, Therefore, Where X 20 is the standstill reactance of the rotor. The rotor circuit is shown below:
