The Heating of Induction Motors
Transactions of the American Institute of Electrical Engineers, 1909The object of this paper is to show the limitations imposed on the designer of induction motors by the heating of the machine, and also to show how this heating may be predetermined.

On speed control of induction motors
Proceedings of 1995 American Control Conference - ACC'95, 1996Espinosa and Ortega (1994) presented an output feedback globally stable speed tracking controller for induction motors. An important feature of the scheme is that it does not require state observers, thus reducing the computational burden, a critical limiting factor in physical implementations.

Induction motor drive parameters identification
IEEE Transactions on Power Electronics, 1998The paper deals with real-time identification of the rotor parameters of the induction motor drive. The model reference adaptative control technique has been used for synthesising two identifiers. An appropriate choice of the reference model allows a Lyapunov function to be built by means of which the updating law of the rotor time constant can be ...

Magnetic noise in induction motors is caused by the vibration of magnetic parts produced by the varying forces associated with the changing flux density in the adjacent air parts of the magnetic circuit. Torsional vibration of the motor is caused by unbalanced windings or applied voltages.

Publisher Summary With the recent advances in microprocessor technology, it is now possible to develop commercially viable drives that allow alternating-current (a.c.) asynchronous induction motors to be controlled with the accuracy and the response times, which are necessary for servo applications.

Good motor performance depends on the electrical and mechanical design, as well as on motor operating conditions. Sound mechanical design reduces the vibration levels and extends the life of the machine. Over the years, the demand continues to grow for motors with greater reliability.

It was explained in Section 4.8 that a two-axis representation of the induction motor can be made in two different ways. The more direct method, in which the reference frame is attached to the primary element (normally the stator), is useful for many purposes, particularly in making calculations for a machine with a single secondary winding.

Neurocontroller for induction motors
ICM 2000. Proceedings of the 12th International Conference on Microelectronics. (IEEE Cat. No.00EX453), 2002In this paper, the artificial neural network (ANN) is used to identify and control an induction machine by performing as a field-oriented control (FOC). The control system designed in this work is called the neurocontroller, and it is trained to reflect the nonlinear behavior of an indirect vector controller and of the PI controller used in the control

The chapter deals with general description of an induction motor followed by different faults. First, construction of induction motor has been discussed. Then a review of induction motor fault has been presented. Faults like rotor broken bar, mass unbalance, stator faults, single phasing, crawling, bearing faults, etc.
