Abstract:
This research paper analyzes the effects of different winding layouts in an interior rotor, surface mounted, Permanent Magnet Brushless DC (PM BLDC) motor, with design parameters fixed. Generally the winding layout of the stator is fixed for a certain slot to pole configuration, but this paper explores the possibility of having suitable winding patterns as per need, using a concept of “Back EMF Wave Shaping”. It is shown that optimization of certain motor parameters, can be done by adjusting the winding arrangement.
