Abstract

The present invention provides a rotary machine having a stator of a compact configuration. A stator (20) of a resin-molded rotary machine has a stator core (21), coils, terminals (50), and a molding portion (60). The stator core (21) is formed by laminating steel plates. The coil is provided on the stator core (21). The terminal (50) is connected to the lead-out wire part which is the end part of the wire which forms a coil, and a lead wire. The molded part (60) covers the end of the coil on the one end face side of the stator core (21) in the stacking direction. The terminal (50) is on one end face side of the stator core (21), and the part connecting the lead wire part is arranged inside the molding part (60), and the external connection part (51) connecting the lead wire is connected from the molding part (60) to A rotating shaft (shaft) (18) side of a rotor (12) of a rotary machine protrudes.

Description

technical field [0001] The present invention relates to a rotating machine such as a motor or a generator. Background technique [0002] Technology related to rotary machines is proposed. For example, Patent Document 1 discloses a terminal structure for a rotating electric machine. This rotating electric machine forms a resin molded part by resin molding a coil end, and has a terminal part integrated with the resin molded part. The terminal portion is provided on one of the resin molded portions provided on both surfaces of the stator core formed by laminating electromagnetic steel sheets. In the rotating electric machine, the terminal portion is provided at a position on the end face side of the resin molded portion in the direction in which the electrical steel sheets are laminated, with the terminals of the terminal portion protruding outward in the radial direction.
