るスロツト付鉄心形モータ。 In a stator having a stator formed by winding an armature coil around a slotted iron core, and a rotor equipped with a field magnet magnetized to a plurality of poles, the energization period of the armature coil is set to the field magnet. The period is the same as that of the cogging ripple that occurs when the magnetic pole boundary of the field magnet crosses the slot of the stator, and the driving torque generated between the armature coil and the field magnet has a torque fluctuation that cancels out the cogging ripple. An iron core type motor with a slot.
