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 .

Executive summary 5 There are two main types of housing systems for layer hens in Australia. The first is conventional or 'battery' cages, which are barren wire cages, set in rows and tiers. A small number of hens are kept in each cage. The second is cage-free systems, which comprise free range and barn. Hens in cage-free systems are .

A Faraday cage can help reduce the effect of electromagnetic radiation. Due to the nature of electromagnetic radiation, two different effects occur simultaneously at the conductive enclosure of the Faraday cage. Figure 3 and Figure 4 show the general principle of a Faraday cage when an electric and magnetic field interacts with a Faraday cage.

Parameter estimation of squirrel-cage motors with parasitic torques in the torque-slip curve . The torque-slip curve of the classical models is smooth because it is assumed that stator and rotor windings are sinusoidally distributed. As a consequence, the air-gap magnetomotive force (mmf) and flux density generated by a winding are also .

Starting of 3-Phase Induction Motors The induction motor is fundamentally a transformer in which the stator is the primary and the rotor is short-circuited secondary. At starting, the voltage induced in the induction motor rotor is maximum (Q s 1). Since the rotor impedance is low, the rotor current is excessively large.
