description | The authors present in this paper the analysis with Finite Element Method (FEM) of the magnetic circuit for
a Brushless DC servomotor with fractional number of slots/pole (9 slots and 10 poles). For this purpose,
FEMM 4.2 software package was used for the analysis. To obtain the waveforms of Back-ElectroMotive Forces
(BEMFs), electromagnetic and cogging torque for servomotor a program in LUA scripting language (integrated
into interactive shell of FEMM4.2) has been created. A comparation with a structure with integer number
of slots/pole (18 slots and 6 poles) was also realized. The analysis results prove that the structure
chosen is an optimal solution: sinusoidal waveforms of BEMFs, improved electromagnetic torque and reduced
cogging torque. Therefore, the operating characteristics of the servomotor with 9/10 slots/poles manufactured
by Sistem Euroteh Company and included in an integrated electrical drives system are presented in this paper. |
