ABSTRACT:
If the motor housing5is manufactured with a resin, the housing5becomes possible to be manufactured by injection molding, so that the housing5can be intended to lower the manufacturing cost by a mass production. Further, the counter measures for insulation such as covering a copper wire7with an insulating tape, interposing an insulator to an opening5aof the housing installing an insulating shim between the coil6aand the housing5become unnecessary. As a result, it becomes possible to expect a cost down of the spindle motor due to the reduction of the cost of the parts for insulating members and the mounting processes. And, further, since a vibration transmitted from the rotor1through the bearing and a vibration caused by an electric switching of the stator6etc. are diminished due to elastic absorbing function of the housing5, rotation noise of the spindle motor can be reduced.
