A Study on the Dimension Design of Ferrite Magnet DC Motor
페라이드 자석 직류전동기의 치수 설계에 관한 연구
Abstract
In this paper, design equations for the calculation of the dimensions and characteristics of the ferrite magnet DC motor are derived. Through the computer iterative calculation applying the parameter survey method with those equations, the design method is presented. The following facts and the propriety of the design method are identified by comparing with the computer simulation results and dimension elements for the proposed motor. (1) The dimension ratio and the pole arc ratio as simulation parameters are in close connection with the dimension elements and motor performance, and those values of the parameter are important factor in determining the reasonable dimension of the motor. (2) It is proved that the minimization of the ferrite magnet volume is possible by representing the permeance coefficient as a function of the flux density ratio only. (3) It is shown that the torque equation suggested by introducing the copper loss area density of the conductors located in the slot is available in the determination of motor dimensions.
