Abstract

Disclosed is an efficient direct connection type air compressor oil-cooling permanent magnet synchronous motor. The efficient direct connection type air compressor oil-cooling permanent magnet synchronous motor comprises a front flange, a motor shell, a stator iron core, a coil, a back flange, a base, a rotor iron core, a rotary shaft and a rotor locking screw; the coil is wound around the statoriron core, and the coil is uniformly arranged around the stator iron core; the rotor iron core is arranged in the stator iron core in a sleeving manner; the rotary shaft is arranged in the rotor ironcore; the stator iron core, the rotor iron core and the rotary shaft adopt a concentric structure, wherein the rotor locking screw is also arranged in the rotary shaft; the rotary shaft extends from the front flange to be directly connected with an air compressor main shaft; the rotary shaft and the air compressor main shaft are tightly locked together through the rotor locking screw, and the aircompressor main shaft can be directly driven through the rotary shaft to rotate; and in addition, an epoxy pouring layer is arranged among the motor shell, the stator iron shell and the coil. By virtue of direct connection between the motor rotary shaft and the air compressor main shaft and by combination with dual-layered V-shaped magnetic steel groove and a cooling flowing channel with ribs, themotor efficiency can reach 97%.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to an oil-cooled permanent magnet synchronous motor of an efficient direct-connected air compressor and a pouring process thereof. Background technique [0002] 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 winding reacts through the armature under the action of the rotating magnetic field to induce a three-phase symmetrical current. At present, the motors used in air compressors are generally three-phase asynchronous motors, which have low operating efficiency, narrow high-efficiency speed range, large starting current, and short service life; It is very large, but the engine torque is very small, and it is bulky and inconvenient to install.
