Web13 de out. de 2024 · Because of the lack of brushes and slip rings, BDFIG is suitable for offshore wind power applications. The machine has two three-phase stator windings with distinct poles, namely, synchronous power winding (SPW) and asynchronous power winding (APW). As shown in Figure 1, SPW and APW are connected to the power grid. WebThere are two types of induction motors. The difference again comes from the structure of the rotor, and the two types are named based on the rotor structure. One type is called Squirrel cage motor and the other is called wound rotor induction motor (WRIM). The rotor of the squirrel cage motor has no winding, and there is no need for the rotor ...
