A rotating electrical machine comprises a stator and a rotor. The rotor includes a rotor iron core in which a permanent magnet is disposed. The rotor iron core comprises a connection part, a plurality of magnetic pole part, a first gap, and a second gap for injection of the adhesive. The connection part is configured to surround a rotational axis. The plurality of magnetic pole parts are provided in an outer portion than the connection part in a radial direction. The first gap is configured to penetrate along an axial direction between the magnetic pole parts in an outer portion than the connection part in the radial direction and in which the permanent magnet is fixed with adhesive. At least one of the second gaps is provided for each of the first gaps in communication with the first gap.

Rotating electrical machine and manufacturing method of rotor

A rotating electrical machine includes a toric stator and a rotator located inside or outside the stator. The stator includes a plurality of teeth radially extending from the center of a circle of the stator with equal gap, and the plurality of coils arranged in order and in layers by the winding wire being turned a plurality of times around the circumference of each of a plurality of teeth. The number of turns of the two respective coils arranged on the circumference of the two adjacent teeth is different.
