摘要： A claw-pole type stepping motor comprises: a rotor assembly shaped substantially cylindrical, and having a center shaft; and a stator assembly composed of two cup-shaped stator units which are coupled to each other coaxially so as to axially sandwich the rotor assembly, and which each include a bobbin having a magnet wire wound therearound, and two pole tooth arrays magnetically connected to each other and shifted in phase from each other by an electrical angle of 180 degrees. In the motor, each stator unit further includes a cover ring which protects the magnet wire wound around the bobbin against resin injected when the stator unit is resin-molded for an integrated solid structure. The motor structured as described above can be successfully resin-molded so as to enable elimination of a motor case, thus achieving downsizing for the dimension of the eliminated motor case while maintaining a sufficient mechanical strength.

摘要： A bearing system in a motor for a floppy disk drive (FDD) apparatus includes a protective cap mounted to one side of the motor, a first pivot bearing arranged movable to and from the protective cap in an axial direction of a rotary shaft, a thrust spring provided for urging the first pivot bearing in the axial direction of the rotary shaft, the rotary shaft having a rotor fixedly mounted thereto and rotatably supported at one end by the first pivot bearing and at the other end by a second pivot bearing mounted to a base for installation of the motor, and an alignment bushing arranged through which the rotary shaft of the motor extends without direct contact and closely fitted into a positioning hole provided in a plate to which the motor is secured. The rotary shaft remains not in direct contact with (spaced apart from) the alignment bushing and, acting as a leadscrew, can thus rotate at a higher accuracy, eliminating intrinsic drawbacks of the FDD motor. In rotation, a thrust is exerted across the first pivot bearing in the motor to the rotary shaft and such wearing properties as between the thrust spring and the ball in the conventional system needs not to be accounted for. Also, the thrust will be lessened by a combination of the base portion of the first pivot bearing and the protective cap which both are made of low-cost synthetic resin.
摘要翻译：用于软盘驱动器（FDD）装置的电动机中的轴承系统包括安装在电动机的一侧的保护帽，第一枢转轴承，其可沿旋转轴的轴向方向移动到保护帽和从保护帽的轴向方向移动，推力弹簧，其设置用于沿着旋转轴的轴向推动第一枢转轴承，旋转轴具有固定地安装在其上的转子，并且在一端由第一枢转轴承可旋转地支撑，另一端由安装到第一枢转轴承的第二枢转轴承电机的安装基座和布置的对准衬套，马达的旋转轴通过该套筒直接接触并紧密地配合到设置在电机固定到的板上的定位孔中。旋转轴保持不与对准衬套直接接触（间隔开），并且作为丝杠可以以更高的精度旋转，消除了FDD电动机的内在缺陷。在旋转中，将电动机中的第一枢转轴承的推力施加到旋转轴，并且不需要考虑常规系统中的推力弹簧和球之间的这种磨损特性。此外，通过第一枢转轴承的基部和保护盖的组合，两者都由低成本合成树脂制成，推力将减小。

摘要： There is provided a stepping motor including: a stator assembly; a rotary shaft which includes a lead screw portion and a plain portion with a rotor magnet disposed thereon, and which has both ends thereof rotatably supported by respective bearings; and a thrust mechanism which includes a resilient member provided in a recess formed at one end of the rotary shaft positioned toward the lead screw portion, and adapted to give an axial thrust force to the rotary shaft, and a point-contact member provided between the resilient member and one bearing of the respective bearings, the one bearing rotatably supporting the one end of the rotary shaft positioned toward the lead screw portion. Thus, the thrust mechanism is located out of and apart from the stator assembly which includes coils to radiate heat, and therefore is prevented from suffering influences from the heat radiated by the coils.
