Abstract

The invention discloses a water-cooled motor stator which comprises a stator base, a stator iron core, an iron core pressing plate, a water cooling system and an end part protection system. The statorbase is a cage-shaped base, the stator iron core is composed of a tooth part and a yoke part, and the water cooling system is composed of a notch cooler and a yoke part cooler; the yoke cooler is composed of a yoke water pipe and an integrated bracket. The end protection system is composed of an integrated bracket, an end inner cover, an end outer cover and high-thermal-conductivity silicone grease. The stator base and the stator iron core are assembled into a whole, and the components form the water-cooled motor stator; the water-cooled motor stator provided by the invention is high in cooling efficiency, good in reliability and high in integration level, and the problems of protection and cooling of the end part of a high-power density motor are solved well.

Description

technical field [0001] The invention belongs to the technical field of motor cooling, and in particular relates to a water-cooled motor stator and a motor with the stator. Background technique [0002] Permanent magnet motors have the advantages of simple structure, reliable operation, low loss, high efficiency, and direct drive control. Therefore, they are widely used in various industrial fields such as ship propulsion, mining, metallurgical rolling, and wind power generation. In order to meet the requirements of different application environments and different driving loads, higher requirements are put forward for the size and weight of the motor. Therefore, the requirements for the electromagnetic heat load of the motor are also getting higher and higher, that is, the power density of the motor is required to be higher and higher. . [0003] During the operation of the motor, losses will be generated, which will be converted into heat inside the motor, causing the tempe...
