ABSTRACT:
A three-phase DC brushless motor and coil winding method provide a coil winding enabling consistent starting with PWM sensorless driving by suppressing the DC offset component of the induced voltage resulting from an imbalance in the motor coil windings. The method of winding the armature winding of the three-phase DC brushless motor renders the difference in mutual inductance substantially zero.
