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 ...

[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 ...

9th IET Professional Development Course on Electric Traction Systems, 2006
This paper describes the use of electrical machines as the prime mover in railway locomotives and vehicles. First, the loading of traction machines is examined from knowledge of vehicle movement dynamics within the traction duty cycle. Then the operation of the principal types of traction machine - DC, synchronous and induction (asynchronous) motors ...
