Water-cooled permanent magnet synchronous motor

Abstract

The invention discloses a water-cooled permanent magnet synchronous motor, relates to the technical field of permanent magnet synchronous motor structures, and is mainly used for solving the problem that an existing permanent magnet synchronous motor is not ideal in cooling effect. The main structure is as follows: the motor comprises a motor housing, a front end cover, a rear end cover and a motor rotating shaft, wherein a rotor is arranged on the motor rotating shaft, a stator is arranged on the inner wall of the motor housing, a water channel interlayer arranged around the motor rotating shaft is arranged in the motor housing, a water inlet channel and a water outlet channel which are communicated with the water channel interlayer are arranged in the rear end cover, and a water inlet connector and a water outlet connector are further arranged on the rear end cover. According to the water-cooled permanent magnet synchronous motor provided by the invention, the water channel interlayer is arranged in the motor housing, and heat generated by operation of the motor can be rapidly taken away through flowing of cooling water in the water channel interlayer.

Description

technical field [0001] The invention relates to the technical field of permanent magnet synchronous motor structure, in particular to a water-cooled permanent magnet synchronous motor. Background technique [0002] The permanent magnet synchronous motor is a kind of synchronous motor. The synchronous motor is the heart of the power system. It is a component that integrates rotation and static, electromagnetic change and mechanical movement, and realizes the transformation of electrical energy and mechanical performance. It is widely used in high-performance servo and motion control fields. During the operation of the permanent magnet synchronous motor, its iron core and coil will continuously generate heat, which will increase the temperature of the permanent magnet synchronous motor. Therefore, certain measures must be taken to reduce the temperature of the permanent magnet synchronous motor. [0003] At present, the common heat dissipation methods of permanent magnet syn...

Problems solved by technology

[0004] However, the heat dissipation efficiency of the former is slow, and the heat dissipation effect is not ideal.

And the latter will lead to the bloated structure of the whole device, which is inconvenient for installation and maintenance.

Moreover, the heat dissipation of external equipment is indirect cooling for the motor, and the heat dissipation effect is poor.
