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. The rotor of an induction motor can be a squirrel cage rotor or wound ... WebFig. 23.27 presents a topology consisting of a doubly fed induction generator (DFIG) with ac/dc and dc/ac converters, that is, a four-quadrant ac/ac converter using IGBTs connected to the rotor windings. In the DFIG topology, the induction generator is not a squirrel-cage machine, and the rotor windings are not short-circuited. Instead, they are used as the …
WebEfficiency of the cast copper induction machine is shown in Figure 3. Note that the curves are limited by the torque capability of the machine and that efficiency stays relatively high at high rotor speeds. Efficiency is lower at low rotor speeds, as one would expect because motors are torque machines and output power is the product of torque ...
