摘要： A rotating electric machine apparatus including: a rotating electric machine (REM) including a rotor and a stator; an inverter device including an inverter circuit (IC) for driving the REM and an inverter control unit (ICU) for controlling the IC; a detector, in which a first antenna is connected to a resonance circuitry, which is mounted to the REM and has a resonance characteristic that changes depending on a change in a physical quantity; and a detection processor receiving a response radio wave indicating a detection result of the change in the physical quantity from the first antenna while transmitting a transmission radio wave at a set carrier frequency from a second antenna, and comparing the detection result and the set value, to thereby obtain an abnormal state in the REM. The ICU controls output of the IC in accordance with an abnormal state signal from the detection processor.

摘要： This method includes: a coil assembly step of combining a plurality of coil units to form a coil basket; a core insertion step of inserting inner cores of in the radial direction to the coil basket; and a fixation member insertion step of inserting a fixation member to the outer circumference of the inner core. In the core insertion step, the radial-direction position of the coil basket is retained at a core insertion time position shifted outward in the radial direction relative to a normal position after armature completion, and the inner cores are inserted in the radial direction to the coil basket. After the core insertion step, the radial-direction positions of the coil basket and the inner cores are moved inward in the radial direction to the normal position after armature completion.

摘要： A terminal block is fixed to a frame holding a stator and in phase with the stator whereas a part of an outside wire is fixed to a case. Hence, a bus bar extracted from a connection plate is welded to the terminal block hardly under the influence of a tolerance caused by integration of components and a tolerance of assembly. Even when a load applied from the outside gives rise to a phase difference between the case and the frame, a tolerance can be absorbed by the outside wire. Accordingly, a load applied to a weld portion of the terminal block and the bus bar can be reduced.
摘要翻译： 端子块固定在保持定子并与定子同相的框架上，而外部线的一部分固定在壳体上。 因此，从连接板上抽出的汇流排几乎不受由零件的组合和组装公差引起的公差的影响而被焊接到端子块上。 即使当从外部施加的负载引起壳体和框架之间的相位差时，公差也可以被外部线材吸收。 因此，可以减少施加到端子台和母线的焊接部分的负载。
