摘要： Disclosed herein is a reliable inner rotor type miniature brushless motor structure wherein, while a field coil is fixedly disposed onto the inner wall of a housing, an end flange is fixedly disposed into one end of the housing from where tap wires of the field coil are drawn out, so that the tap wires exposed from the end-flange side end of the housing can be connected to wiring substrates fixedly disposed onto the outer periphery of the end flange without the need to bend the wiring substrates, and further so that power feed lands can be large enough to reduce the likelihood of wiring breakage and other problems.

摘要： [Problems] A motor shaft for a micromotor where a high reduction ratio can be obtained by a speed-reduction gear mechanism and where high coaxiality between the motor shaft and a pinion can be achieved.[Means for Solving problems] The invention is based on the fact that, because a micromotor has a very small motor torque, even a pinion having a diameter smaller than that of a shaft has sufficient strength for the motor torque. Based on this, the motor shaft of the invention has a pinion integrally formed on the front end side of the shaft and the pinion has an outer diameter equal to or less than that of the shaft. Because the pinion can be sufficiently reduced in diameter, a high reduction ratio can be obtained by a speed-reduction gear mechanism. In addition, since the pinion can be integrally formed on the motor shaft, high coaxiality between the shaft and the pinion can be achieved.
摘要翻译： [问题]可以实现通过减速齿轮机构获得高减速比并且电动机轴和小齿轮之间高同轴度的微型电动机的电动机轴。解决问题的手段本发明是基于以下事实：由于微电机具有非常小的电动机转矩，所以即使直径小于轴的小齿轮也具有足够的电机转矩强度。基于此，本发明的电动机轴具有一体地形成在轴的前端侧的小齿轮，小齿轮的外径等于或小于轴的外径。由于小齿轮的直径可以充分减小，所以通过减速齿轮机构可以获得高的减速比。此外，由于小齿轮可以一体地形成在电动机轴上，所以可以实现轴和小齿轮之间的高同轴度。
