摘要： In a rotary electric machine including a stator core and a stator winding received in slots of the stator core, a cooling medium baffling device is provided which comprises a cooling medium baffle plate fixed to the inner peripheral edge of one end of the stator core by mounting bolts protruding axially from the end of the stator core, wherein the circumferential position of each of the mounting bolts is displaced from the circumferential position defining the boundary between the different modes of phase currents flowing through the coils constituting the stator winding, thereby effectively eliminating generation of excessive heat due to excessive eddy current losses occurring locally at the end of the stator core.

摘要： An electric rotary machine is provided with a stator having a stator core of laminated iron plates with a given lamination thickness in an axial direction of the machine and a stator winding wound around the core and a rotor rotatably disposed inside the stator, having a rotor core and a rotor winding. The axial length of the stator core is selected with respect to that of the rotor core in such a way that, when the rotor is thermally extended, the end of the rotor core never extends beyond the end of the stator core. With such a constructional arrangement, there is eliminated an excessive temperature rise at the ends of the stator core, and prevented an insulation deterioration of the stator winding and the burning of the stator core.

摘要： A fault detection apparatus for a rotor winding of a rotary machine comprises a peak value hold circuit, a peak value processor and a monitor. The peak value hold circuit holds peak value of a pulsing magnetic flux waveform supplied from a magnetic flux sensor mounted in proximity to a surface of a rotor, for a necessary time period. The peak value processor sequentially compares the peak value held in the peak value hold circuit with corresponding one of pre-stored peak values of the pulsing magnetic flux waveform to determine if a difference therebetween exceeds a preset level. The monitor indicates the presence or absence of fault based on the result of the comparison of the processor.

摘要： In a motor having a pawl-shaped magnetic pole, if a coil is wound like a ring shape so as to be formed, one leader line can be generally drawn out to an external portion from a position close to an outer periphery of a stator, however, the other leader line is drawn out to the external portion from an inner periphery of the stator. Accordingly, the leader line occupies a part of the inner space formed by the stator core, so that there is generated a problem that a space factor of the coil is reduced. Accordingly, an object of the present invention is to improve the space factor of the coil. In order to achieve the object mentioned above, a space passing wirings of a plurality of coils therethrough is provided in a part of the pawl-shaped magnetic pole of the stator core of the stator having the pawl-shaped magnetic pole. Accordingly, one of leader lines of the coil is drawn out from an outer peripheral portion (or an opposite side to a side facing to the rotor) of the stator, and the other is drawn out in an axial direction from the space of the claw-shaped magnetic pole of the stator. Therefore, it is possible to do away with an influence by the leader line, it is possible to increase a winding number of the coil even in the same space, and it is possible to improve a downsizing of the motor.
摘要翻译：在具有棘爪状磁极的电动机中，如果线圈被卷绕成环状形成，则可以将一条引线一般从靠近定子外周的位置抽出到外部，然而，另一个引导线从定子的内周被拉出到外部。因此，引导线占据由定子铁芯形成的内部空间的一部分，从而产生线圈的空间系数减小的问题。因此，本发明的目的是提高线圈的空间系数。为了实现上述目的，在具有棘爪状磁极的定子的定子铁心的棘爪状磁极的一部分上设置有多个线圈的配线的空间。因此，线圈的引线之一从定子的外周部（或与转子相对的一侧的相反侧）拉出，另一方从爪的空间沿轴向拉出定子的磁极。因此，可以避免引线的影响，即使在相同的空间也可以增加线圈的绕组数，可以提高电动机的小型化。
