摘要： A motor includes a shaft extending along a center axis, and a first groove that is recessed in a radial direction and extends in an axial direction, on an outer side surface of the shaft. The motor includes a stator core into which the shaft is inserted, and a rotation restrictor that is inserted into at least a portion of the first groove and restricts the stator core and the shaft in a circumferential direction. A carrier vehicle is equipped with the motor further including a lead wire extending from the stator. The shaft includes a shaft portion and a flange portion that overhangs to a radially outer side from one side of the shaft portion in the axial direction. The flange portion includes an opening through which the lead wire passes. The opening includes a notch connected to an outer side surface of the flange portion. The opening of the motor is positioned above the center axis.

摘要： An impeller includes a substantially cylindrical cup portion arranged to rotate about a center axis, a plurality of blades fixed to an outer circumferential surface of the cup portion for unitary rotation with the cup portion to draw air from one axial side and discharge the air to the other axial side, and an annular connector portion arranged to interconnect the blades. The connector portion has a substantially cylindrical shape in a position spaced apart about 70% to about 90% of the radial length of the blades from the base of each of the blades on the outer circumferential surface of the cup portion, and the ratio of a total axial height of the connector portion to a total radial gap between the outer circumferential surface of the cup portion and the inner circumferential surface of the connector portion is equal to or smaller than about 0.9.

摘要： A rotary electric machine includes a stator in which windings are arranged around a plurality of main poles of a stator core, and a hybrid type rotor arranged with an air gap between the stator and the rotor has a step angle for the rotor of about 4.09° and uses metal bearings for supporting a rotor shaft of the rotor. Setting of the step angle for the rotor to be about 4.09° can make a rotation angle of the rotor caused by excitation of the windings by an input pulse signal larger as compared with a typical motor having a step angle of about 1.8°. With this unique arrangement, the rotor can be rotated at higher speeds, increasing the motor efficiency. Therefore, the motor output at approximately the same level as that of a conventional motor can be obtained without keeping the air gap high precision. Due to this, even if inexpensive slide bearings, i.e., metal bearings to support the rotor, are used, the performance equal to or higher than that of the conventional motor can be ensured, resulting in a large cost reduction.
摘要翻译：旋转电机包括定子，绕组围绕定子芯的多个主极布置，并且在定子和转子之间布置有空气间隙的混合型转子具有约4.09°的转子的台阶角并使用金属轴承来支撑转子的转子轴。与转子角度约为4.0°的典型电动机相比，将转子的转角设定为约4.09°可以使由绕组的励磁引起的旋转角大于输入脉冲信号。通过这种独特的布置，转子可以以更高的速度旋转，从而提高电机效率。因此，可以在不保持气隙高精度的情况下获得与常规电动机大致相同水平的电动机输出。由此，即使使用廉价的滑动轴承，即用于支撑转子的金属轴承，也可以确保等于或高于常规电动机的性能，从而大大降低成本。

摘要： A magnetic circuit suitable for a self-held type rotary solenoid while maintaining properties, reducing cost, e.g., a material cost, and making the rotary solenoid smaller in size is provided. The rotary solenoid includes a swing yoke to which two magnets are fixed and a fixed yoke including projection portions at opposite sides thereof. An electromagnetic coil including a major magnetic pole is arranged at a center of the fixed yoke. The rotary solenoid is arranged to define a magnetic circuit extending through one of the magnets, the major magnetic pole, the fixed yoke, the projection portion, and the other magnet at a shortest distance. Therefore, even if a magnet made of a material having a low grade is used, it is possible to maintain sufficient magnetic properties.
