Problems solved by technology

[0007] The air-cooling method increases the ventilation system of the motor, and the wind friction loss is large, and the motor efficiency is low; the cooling is uneven, and the structural components such as the stator core and winding cannot be fully cooled, which reduces the power density and increases the volume of the motor; the noise is large, It cannot be applied in some occasions requiring low noise
[0008] ii In the external water cooling method, the main heat-generating parts of the motor stator are the stator winding and the stator core. The heat generated by the stator winding must first be transmitted to the stator core,

Abstract

A outside watercourse evaporative cooling horizontal motor features adopting sealing between stator housing and front rear endplate, inner sleeve two ends and front rear endplate, constituting inclosed stator cavity to seal whole stator in stator cavity, evaporative cooling media implanting in stator cavity. Evaporative cooling media free-flow in stator cavity and can penetrate into stator core interior. Stator winding and stator core etc heating part generated heat quantity is conducted evaporative cooling media, when evaporative cooling media main unit temperature rises to corresponding pressure saturation temperature, media bubble and generate phase transition heat sink and vapour. Vapour is condensed and liquefied by flowing in water jacket cylinder inner wall in stator cavity upper part, then flowing back in stator cavity bottom evaporative cooling media, forming non - external power stator evaporative cooling self -circulation.

Description

technical field [0001] The invention relates to various small and medium-sized horizontal motors, in particular to an evaporative cooling horizontal motor. Background technique [0002] The motor is a kind of electromechanical energy conversion mechanism. In the process of electromechanical energy conversion, losses are inevitable, mainly including core loss, winding loss, mechanical loss, etc., and most of these losses eventually turn into heat, which makes the various parts of the motor The temperature rises. Therefore, the selection of cooling methods for small and medium-sized horizontal motors is an important part of motor design. [0003] Due to its small power, the cooling method of small and medium-sized horizontal motors is not as complicated as that of large generators, and air cooling is currently the dominant method. Its main structural form is blown from the outside of the fan, the axial ventilation surface is cooled, and the external fan installed on the rota...
