induction motor

n
(Electrical Engineering) a type of brushless electric motor in which an alternating supply fed to the windings of the stator creates a magnetic field that induces a current in the windings of the rotor. Rotation of the rotor results from the interaction of the magnetic field created by the rotor current with the field of the stator

A medium-voltage converter-controlled torque motor replaces the AC induction motor.
To solve this task Ansys Maxwell & Simplorer software both for induction motor design and transient simulation were used [1, 2].
ABSTRACT: A study of stator slot design for induction motor is necessary in order to additional improvement of efficiency and reduces the winding loss.
Controlling action of electrical drives used in various systems and process control, particularly an induction motors, became very important for its suitability in system design in industry & it's so many other advantages such as time, energy & sensitivity The most important data to be drive the induction motor are frequency, temperature, voltage, current, and speed.
The advantage of the induction motor is that there is no physical electrical connection between an electrical source and the rotor, meaning that the motor is brushless, and without slip rings, both of which create frictional losses and wear points that ultimately require maintenance and parts replacement.
When there was a need for the analysis of a wave current in a system in which the three-phase induction motor was fed from a three-phase bridge inverter it appeared that there were no adequate mathematical models of such a system in available literature.
Effects produced by real sags on an induction motor
In the induction motor cross section sketch of Figure 1, the stator has a three-phase AC winding to create a rotating magnetic field.
In modern control theory, the induction motor is described by differential mathematical models, suitable to the employed control method [2].
The demands for improved energy savings combined with precision operation has increasingly led engineers to specify permanent magnet synchronous motors (PMSMs), which are more efficient and accurate than an induction motor and a fraction of the cost of a large servomotor.
The topics include control models for synchronous machines, high-gain observers in the robust feedback control of induction motors, the experimental evaluation of nonlinear control design techniques for sensorless induction motors, the adaptive output-feedback control of permanent-magnet synchronous motors, the nonlinear state-feedback control of three-phase wound rotor synchronous motors, and applying induction motor control in high-speed train electric drives.
