Abstract

PURPOSE:To obtain a vibration simply by winding coils only around two poles of the rotor that is made of three-slot core, by providing a noise preventing element in the slot between both coils and by making the quantity of unbalance of the rotor greater. CONSTITUTION:The coils 3, 3 are wound only around the two poles 2, 2 of the rotor that is made of three-slot core. The noise preventing element 4 is put in the slot 5 between the two coils 3, 3 and is connected to the segments 7, 7, 7 of the commutator 6. A pair of permanent magnets 9, 9 and the bearing 10 are fixed to the case 8. Since the coils are wound only around two poles, the quantity of unbalance in turning the rotor is greater, a vibration can efficiently be obtained from the entire motor.
