Switched Reluctance Motors

Switched reluctance motors are promising candidates for a wide variety of drive applications. The theoretical description of such motors is often reduced to the rather simple but clear concept of Psi-I characteristics. In contrast to this, the machine itself is a real electrical machine and must therefore be analysed as done with conventional machines although the experimental machine is constructed as simple as possible. The paper will describe first some well known basics connected to very short machines and flux. In a next step the calculation of stray flux quantities by aid of 3D-FEM is discussed and finally a comparison of calculation and experimental readings is given. not assigned KP: Partner aus der Industrie (anonym)
