发明名称 Rotor motor with a resin coil bobbin
摘要 The present invention provides a motor having an urging member for urging a rotor disposed oppositely to a stator in the axial direction, in which the rotor is rotated in a state under an urging force of the urging member, characterized in that a positional regulation part (bearing) for regulating the position of the rotor in a thrust direction under the urging force is integrally provided in a coil bobbin made of resin which has metallic stator cores making up the stator formed by insert molding. Therefore, the positional accuracy of the positional regulation part (bearing) with respect to the stator is made better. Thereby, the positional accuracy of the rotor with respect to the stator is also improved, so that the torque up is enabled.
