WebIf an induction motor is driven above synchronous speed it will deliver power to the system, with a slip of about −0.05 at full load. It has the advantage of simple … WebThus, the induction machine can work as an electrical generator only at speeds higher than the synchronous speed. The generator operation, for this reason, is often called the supersynchronous operation of the induction machine. As described in the preceding text, an induction machine needs no electrical connection between the stator and the rotor.
WebThe mmf rotates at synchronous speed, set by supply frequency and the number of poles in the machine. In an induction machine the air gap of the machine is designed to be … WebInduction generators are seldom used because they require reactive power either from the power system or from an external capacitor bank. The induction generator, however, does not have to operate at only one …
Websynchronous speed would result in no induced rotor current, an induction motor always operates slower than synchronous speed. Thus, the operation of induction motor results to losses and power output as show in Fig ure 1 below. Figure 1. Power flow diagram of 3-phase induction motor .
