Chapter 4 - Induction (AC) motor Induction motors are widely used in industry. In this chapter some of the basic features are described. 4.1 Fundamentals An induction motor converts electrical energy into mechanical energy. Converting the energy is based on electromagnetic induction. Because of the induction phenomen

induction motor is more rugged and work more efficiently compared to wound-rotor induction motor. If supply voltage and frequency are constant, then a squirrel-cage induction motor runs at a constant speed which makes it suitable for use in constant speed drive [1, 2]. Several standard designs of squirrel-cage induction motors are

period of time. More than 300 million industrial electric motors are installed worldwide [1]. AC motors are chosen prior to DC motors as it requires a single power source whereas DC machines require separate power sources to the rotor and stator of the motor. Apart from this, there are other factors which make induction motors

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.

A linear induction motor (LIM) is basically a rotating squirrel cage induction motor opened and spread-out . motor, the losses can be reduced to improve the efficiency of single sided linear induction motor which is simple in design, low mechanical loss, high acceleration, and deceleration than other traditional motors. Finally, with much .

prevention of voltage instability due to induction motors is an important concern. The prevention of induction motor stalling by switching a capacitor at the induction motor bus is studied in [1], [2], [4], [6] and [7]. It has been mentioned in [2] that if a capacitance of a particular value has to be switched, it has to be done

AC Motors AC motors are used worldwide in many applications to transform electrical energy into mechanical energy. There are many types of AC motors, but this course focuses on three-phase induction motors, the most common type of motor used in industrial applications. An AC motor of this type may be part of a pump or fan or

induction motor performance calculations. At rated load, the additional losses are referred to as stray-load losses. For small to medium sized induction motors these losses vary typically within the range 0,5% - 3% of the motor input power [1, 2]. Measurements have, however, shown that these losses can be even larger [2, 3].
