| Abstract | ||
| This paper presents a comparative analysis of 3-phase permanent magnet brushless dc motor drive having slightly different phase-emf waveform. Permanent magnet brushless dc motors of 12-slot/10-pole and 6-slot/4-pole are considered in this project. Both brushless dc motors have a permanent magnet surface-mounted rotor, and the stator windings employ single-tooth wound coils such that the phase-emf is trapezoidal. Therefore, both motors are conducive for rectangular-shaped stator phase current excitation in order to produce constant torque output. The mathematical model for BLDC operation and individual definition of the system blocks will be described. The model is later simulated in MATLAB/Simulink version 8. The generated 12-slot/10-pole and 6-slot/4-pole phase-emf data from finite element analysis are used in the Simulink blocks to examine the dynamic performance of both permanent magnet motors. | ||
