Trójfazowy generator synchroniczny wzbudzany magnesami trwałymi, jako źródło energii elektrycznej w agregacie prądotwórczym

In the article, the conception of standby diesel unit with permanent magnet generator was presented. Design issues and possibilities of power unit were discussed. Three computational models of permanent magnet synchronous generator were shown. A schedule of the magnetic induction field was expressed in the air gap of all three electromagnetic circuits structures. As the results of finite element method calculation, the course of cogging torque versus rotor revolution for one slot pitch was presented. The cross section with graphically presentation of magnetic induction in particular parts of electromagnetic circuits was shown. In this paper, the characteristics of output voltage and efficiency versus power load were expressed for Tyree electromagnetic circuits of permanent magnet generators.
