Proceedings of the 19th Electrical Electronics Insulation Conference, 2003
The author discusses those factors which determine the efficiency and rating of polyphase AC induction motors. The loss mechanisms are described and are related to the performance and design characteristics of the motor, such as the operating flux density, the winding turns distribution, the current density in the windings, the motor speed torque ...

Alternating current (AC), varying sinusoidally at 50 Hz in Europe and Asia and 60 Hz in North America and Japan, is the dominant form of electric power. AC provides the continuously changing magnetic flux linkage needed for electrical transformation. Transformation allows transmission at high voltage and low current, reducing resistive loss with step ...

As was stated in Chap. 5, translating electrical energy into motion is one of the oldest applications of electrical engineering. Both AC and DC motors have been utilized for this purpose. Previously, the universal motor (series connected DC motor) was introduced as a cheap motor that can operate on AC power.

[Proceedings] IEEE 1993 Annual Textile, Fiber and Film Industry Technical Conference, 2002
The standard AC induction electric motor is used in over 90% of all applications. However, the disadvantages of fixed-speed operation have led industrial users to seek and use other means to achieve variable speed drive operation. Recent developments in power semiconductors and microprocessors have resulted not only in economical advantages but also ...

Assuming that for AC electrical machines, the only measurable variables are the currents and the voltages, the mathematical models of the synchronous and induction motors are used to study their respective observability property. If this property is satisfied and under some necessary conditions introduced later, observers are designed to estimate the ...
