Evolution of Axial-Field Electrical Machines

DESIGN OF ELECTRIC MACHINES: Axial Flux Machines

Electrical Machines Computer Simulation by Using Circuit - Field Models

The high performance personal computers (PCs) made possible an impressive development in the domain of the electric machines mathematical models. The circuit-field models become more sophisticated and are used more frequently in computing the electric machines characteristics. In the paper a personal point of view concerning the state of the art and the trends in this domain is presented.

Electrical Machines I

The speed of the machine has to be increased from zero and brought to the operating speed. This is called starting of the motor. The operating speed itself should be varied as per the requirements of the load. This is called speed control. Finally, the running machine has to be brought to rest, by decelerating the same. This is called braking. The torque speed characteristics of the machine is ...

Three-dimensional field computation for permanent magnet electric machines with finite axial magnet length

Using the method of separate variables, the three-dimensional magnet field solution expressed in Fourier’s expansion for permanent magnet (PM) machines with finite axial magnet length is presented in this paper. From the analytic results obtained, much useful and interesting design information for PM machines in three dimensions may be quantitatively deduced. Design curves of the leakage factor...
