8 Φεβ 2021 · It discusses the main types of electrical machines and induction motors, including squirrel cage and slip ring induction motors. The document explains the basic working principle of three-phase induction motors, involving the generation of a rotating magnetic field in the stator that induces current in the rotor.
When a 3 phase stator winding is connected to a 3 phase voltage supply, 3 phase current will flow in the windings, which also will induced 3 phase flux in the stator. These flux will rotate at a speed called a Synchronous Speed, ns.
After this presentation you will be able to: Explain how a three-phase induction motor operates. Compute the synchronous speed of an induction motor and the slip between motor rotor and stator magnetic field. Compute the power that crosses that air gap of an induction motor.
22 Ιαν 2013 · Introduction • A poly phase induction motor consists of two major parts, the stator and rotor • When stator is excited with a.c voltage, rotating field is set up • This field produces an EMF in the rotor winding by mutual induction principle, which in turn circulates current when the rotor is short circuited • This current interacts with the fie...
