Brushless DC Motor Magnetic Field Analysis Based on Equivalent Magnetic Network Model

Established the equivalent magnetic network model for brushless coreless DC motor,analysis and calculate the air-gap magnetic field.Based on rare-earth permanent magnet linearized demagnetizing curve,calculate leakage coefficient of motor through analytically simulated.Calculation and experiment show that the view of equivalent magnetic network model analysis the air gap magnetic of motors,result directly and apply convenient,it's worth extending.
