High-heat-dissipation shell for high-density permanent magnet synchronous motor

Abstract

The invention discloses a high-heat-dissipation shell for a high-density permanent magnet synchronous motor. The high-heat-dissipation shell comprises a rear end cover and a main shell, and the rear end cover is mounted on the outer wall of the rear end of the main shell; a rear circular cover is arranged on the circumferential inner wall of the rear end of the rear end cover; and the rear circular cover and the rear end cover are connected through the welding edges in a welded mode. A screw hole a is formed in the circumferential outer wall of the rear end cover, a junction box is arranged onthe outer wall of the circumference of the upper end of the main shell, a cooling water inlet is formed in the main shell on the front side of the junction box, a cooling water outlet is formed in the circumferential outer wall of the lower end of the rear side of the main shell, and a machine base is arranged on the outer wall of the circumference of the main shell. Cooling water is rapidly injected into the vertical channel and the transverse channel through the pressure of the pump, the cooling water continuously flows back and forth in the vertical channel and the transverse channel, thecontact area is increased, the maintenance condition can be reduced, and heat dissipation is conducted on the motor in a cooling water heat absorption mode, so high heat dissipation of the motor is achieved, and the use performance of the motor is improved.

Description

technical field [0001] The invention belongs to the technical field related to mechanical equipment, and in particular relates to a high-radiation casing for a high-density permanent magnet synchronous motor. Background technique [0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor is represented by the letter M (the old standard is D) in the circuit. Its main function is to generate driving torque, as an electrical appliance or various The mechanical power source, the generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. The permanent magnet synchronous motor is a synchronous motor that is excited by a permanent magnet to generate a synchronous rotating magnetic field. The permanent magnet acts as a rotor to generate a rotating magnetic field. , the three-phase stator windi...
