Abstract
The real brushless DC motor has different permanent magnet pole magnetizati on levels due to the influence of the magnetizer geometry Therefore, this p aper discusses the influence of change in the magnetic parameter on brushle ss DC motor performances. As a result, the unbalanced magnetic force acting on the rotor, cogging torque and torque ripple are examined for spindle mo tor with unsymmetric magnetization distribution.
