Function frequency induction
WebFeb 24, 2012 · Synchronous speed is the speed of rotation of the magnetic field in a rotary machine, and it depends upon the frequency and number poles of the machine. The induction motor always runs at speed less than its synchronous speed. The rotating magnetic field produced in the stator will create flux in the rotor, hence causing the rotor … WebJun 7, 2024 · Induction is the ability of a device or circuit to generate reactance to oppose a changing current (self-induction) or the ability to generate a current (mutual induction) in a nearby circuit. The current flowing in the coil produces a field that expands out of and surrounds the conductor. Energy is stored in that field.
