Porównanie właściwości wysokoobrotowego silnika PM BLDC ze stojanem bezżłobkowym i uśłobkowanym

In the paper the authors compare properties of high-speed brushless DC motor with slots and slotless stator. The authors take in consideration open-slots, half-open slots, closed slots and slotless construction of stator. Depending on type of slots motor have different parameters like electromotive force EMF, ripple and cogging torque. As a result of analyse the authors show waveforms of electromotive force EMF end distribution of induction diagram. Maxwell software is used for simulation.
