Abstract

In a small motor system, DC brushless motor, in which unidirectional current flows, can be adopted. Minato motor is one of the unidirectional current type DC brushless motors. However, recently, the DC brushless motor, in which the bidirectional current flows, is being mainly studied. The unidirectional motor system is easy to control the direction of the torque by each armature winding. Considering the above fact, the authors developed the highly effective DC brushless motor in which the unidirectional current flows.
