permanent magnets

Brushless motor with open-pole stator and permanent magnet rotor characterized by sufficient simplicity of design and manufacturing techniques. It is also relatively economical for asynchronous electric machines. At the same time, it provides much higher quality consumer characteristics. According to the widespread use of traditional designs with internal rotor gearless drive for a number of mechanisms is often necessary to use a design with external rotor. This design is simple, reliable, technological and economical.

We have described the way of modernizing the linear motor to increase its initial forcing. We have found the way to compensate for force ripple. The optimum parameters of modernization have been set, and the results of the experiments have been provided

The design method of brush-less generator with permanent magnets on the rotor and U-similar elements on the stator is given. Recommendations are grounded in relation to designing taking into account the features of construction and on the basis of theory of electromagnetic transformation of energy. These recommendations are taken as a basis of project calculation of basic geometrical sizes of such generator. A generator with permanent magnets, created with the use of the offered method is described. External characteristics for different speeds of rotation are given.
