Abstract :

Designing a two-phase brushless direct current motor (BLDC) and analyzing effects of stator slots structure on the motor operation are main objectives of this paper. At first BLDC motor with three different structures for stator slots is designed by using RMxprt software and efficiency of BLDC motor for different structures in full-load condition has been presented, then the BLDC motor in different conditions by using Maxwell 3D software is designed and with finite element method is analyzed electromagnetically. The results of simulations show that by varying stator slots structure efficieny and operation of motor have changed significantly therefore with correct choosing of stator slots structure intersted operation can be found.
