Abstract
Performance enhancement of permanent magnet brushless dc motor during design is highly desirable. With the application of superior magnetic material Hiperco in place of traditional magnetic material M19 silicon steel, the performance of the permanent magnet brushless dc motor (PMBLDC) can be greatly improved. Compared to standard silicon steel material the Hiperco magnetic material has high allowable flux density, high permeability and low specific iron loss. This paper presents the use of Hiperco magnetic material for the stator core of PMBLDC motor. The 200 W, 24 V radial flux PMBLDC motor is designed analytically and modelled in finite element analysis (FEA) software. The initial design incorporates use of M19 – 29 Ga Cold Rolled Non Oriented (CRNO) silicon steel material for the stator core. The initial design is validated using finite element analysis. In improved design, the conventional stator core material is replaced by Hiperco magnetic material and effect of Hiperco on the efficiency of the PMBLDC motor is analyzed. The improved model with the application of Hiperco is analyzed with FEA technique. It is analyzed that efficiency of PMBLDC motor is considerably improved with application of Hiperco.
