Projekt i badania wysokoobrotowego silnika BLDC z rdzeniem amorficznym

The paper presents analysis of simulation results of a high speed brushless motor for different kinds of the motor magnetic circuit. There are considered four constructions of the stator core: with open slots, half-open slots, closed slots and a slotless core. The design criteria are: the waveforms of phase voltages, amplitude and frequency of cogging torques, the winding inductance values and the frequency of magnetizing the core. A prototype of the motor with amorphous core and half-open slots was designed and realised. The investigation results of the motor are given in a form of the waveforms.
