- Abstract
- This paper proposes a new design of interior permanent magnet (IPM) type brushless DC (BLDC) motor using low-price ferrite magnet which has the similar characteristics as the IPM type BLDC motor that uses expensive NdFeB magnet. In order to replace the NdFeB magnet, the proposed design adopts the structure of the C-shape permanent magnets which are arranged as the flared shape. The characteristics of the proposed IPM motor are compared with the NdFeB IPM motor through the finite element analysis (FEA). It is demonstrated that proposed model satisfied with the characteristics of the NdFeB IPM motor.
