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.
How does an AC induction motor work? Here's a typical, everyday AC induction motor with its case and rotor removed, showing the copper windings of the coils that make up the stator (the static, non-moving part of the motor).
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor that produces torque is obtained by electromagnetic induction from the magnetic field of the stator winding. [1] An induction motor therefore needs no electrical connections to the rotor.
Figure 6-6 The development of induced torque in an induction motor. (a) The rotating stator field BS induces a voltage in the rotor bars; (b) the rotor voltage produces a rotor current flow, which lags behind the voltage due to rotor inductance; (c) the rotor current produces a magnetic field BR lagging rotor current by 90o.
Single Phase Induction Motor Definition: A single-phase induction motor is an electrical motor that converts single-phase electrical energy into mechanical energy using magnetic interactions. Construction : The construction features two main parts—stator and rotor—with the stator receiving AC power and the rotor designed to rotate and drive ...
Induction motors use shorted wire loops on a rotating armature and obtain their torque from currents induced in these loops by the changing magnetic field produced in the stator (stationary) coils. At the moment illustrated, the current in the stator coil is in the direction shown and increasing.
The induction motor is the most common type of electrical motor used in industry, and it’s used in pretty much everything, from elevators, escalators, pumps, fans, conveyor belts, etc. Anything that needs to be moved within a building is probably going to be using one of these motors.
INTRODUCTION. AC induction motors are the most common motors used in industrial motion control systems, as well as in main powered home appliances. Simple and rugged design, low-cost, low maintenance and direct connec-tion to an AC power source are the main advantages of AC induction motors.
