Read 7+ pages speed control of induction motor by emf injection method answer in PDF format. A voltage source inverter is used to control the speed of a three-phase 50 Hz squirrel cage induction motor. Injection of an EMF in the Rotor Circuit. The injected voltage emf needs to have an equal frequency with the slip frequency. Check also: speed and speed control of induction motor by emf injection method The injected voltage emf needs to have an equal frequency with the slip frequency.

However there is no limitation for the phase of that emf.
The frequency of this injected emf must be at slip frequency at all speeds. Here we have discussed about the EMF Injection in the rotor circuitEmf injection in rotor circuit is the type of speed control from rotor sideEmf Injection. One motor is connected to three-phase supply and other is work from the feed induced emf of the first motor through slip rings. From stator side i. This method is applicable only for slip ring induction motor. These EMFs are applied at the rotor by a suitable source whose frequency should be same as slip frequency.
