Abstract

The invention discloses a motor stator cooling structure and a motor. The cooling structure comprises a stator iron core (1) and a stator support (2) arranged on the periphery of the stator iron core (1). A cooling water pipe is embedded in the stator support (2), and is spirally wound around the axis of the stator support (2). The cooling water pipe comprises a first water pipe (3) and a second water pipe (4), which are embedded to each other. One end of the first water pipe (3) and one end of the second water pipe (4) are connected to a water inlet joint (5) and a water outlet joint (5) on the axial end of the stator support (2). The other end of the first water pipe (3) and the other end of the second water pipe (4) communicates with each other through a connection head (7). According to the invention, heat dissipation efficiency can be increased, thickness of a water sleeve is reduced and motor weight is reduced.

Description

Technical field [0001] The present invention relates to the technical field of motors, and in particular to a motor stator cooling structure and a motor. Background technique [0002] At present, most motors have coils made of enameled wire. When the motor is working, the motor will inevitably generate heat. If the heat cannot be transferred out in time, the excessively high temperature of the motor will damage the enameled wire insulation and cause short circuits. . At present, the cooling methods of electric motors are air-cooled and water-cooled, and water-cooled has higher heat transfer efficiency. The general treatment of water cooling is to add a water jacket or pre-embedded pipelines. The water jacket needs to be turned or milled out on the surface of the water jacket; the embedded pipeline needs to be connected to the water supply system at the end of the motor, so the pipeline needs to be turned back inside the water jacket, which increases the thickness of the water j...
