WebApr 11, 2024 · In induction motors, the stator’s rotating EMF induces an opposing EMF in the rotor wires, causing it to spin (via Faraday’s Law & Lenz’s Law). Induction motors are often called “asynchronous” motors because their rotational frequency is always lower than the AC frequency. WebOne field acts as a sort of environmental field and the second, a time varying field, re- acts with the first to drive the rotor. In induction motors the ‘environmental’ field is supplied …

WebApr 13, 2024 · 1 Introduction. Induction motor (IM) is widely used in industry due to its ability to operate in harsh environmental conditions, less maintenance requirement, and … WebMay 30, 2024 · In an induction motor, the rotor poles are formed by the action of the stator magnetic field. The number of rotor poles must always match the number of stator poles. For most other types of motors, the rotor is constructed so that the number of rotor poles matches the number of stator poles. lutheran church of australia australia
