Abstract: A rotating electric machine includes a stator, a rotor, and a coolant supply passage. Coils are wound on the teeth of the stator. The rotor is disposed coaxially with the stator, and has an outer circumferential surface that faces respective distal end faces of the teeth with a constant gap formed therebetween. The coolant supply passage is disposed inside the rotor, and is configured to eject a coolant from a coolant outlet of the outer circumferential surface of the rotor toward the distal end face of a corresponding one of the teeth so as to supply the coolant to the gap. A discharge groove is formed in the distal end face of the corresponding tooth. The discharge groove is inclined radially outwardly of the stator, from a coolant supply position as an axial position of the stator facing the coolant outlet, toward one edge of the distal end face of the corresponding tooth.

Abstract: In a rotor manufacturing method, a magnetic body is moved by being pushed by a pusher along a guide surface of a guide portion, and the magnetic body is in a stated of being biased to the guide surface since the magnetic body is urged by a restriction portion. Therefore, the magnetic body can slide reliably between the guide portion and the restriction portion while restricting an insertion posture of the magnetic body. Thus, even if a wall surface of a magnet insertion hole is provided with a protrusion, when the magnetic body slides with the guide surface as a reference, the magnetic body will not abut against the protrusion, and the magnetic body can be reliably loaded into the magnet insertion hole.

Abstract translation: 在转子制造方法中，磁体通过沿着引导部的引导面被推动器推动而移动，并且由于磁体受到限制的推动，所以磁性体被偏置到引导面上 一部分。 因此，在限制磁体的插入姿势的同时，磁体能够在引导部和限制部之间可靠地滑动。 因此，即使磁体插入孔的壁面设置有突起，当磁体以引导面作为基准而滑动时，磁体也不会抵靠突起，并且可以将磁体可靠地装载到 磁铁插入孔。
