Abstract

The invention discloses a supporting protection device for a permanent magnet synchronous motor. The supporting protection device comprises a protective cover and an auxiliary rack, wherein the protective cover comprises a basic shell and blocking rings; the basic shell comprises a left end ring, middle rings and a right end ring; the middle rings are uniformly arranged between the left end ring and the right end ring; and the blocking rings are arranged on the middle rings and the right end ring in a sleeving manner. The mounting method comprises the following steps: 1), mounting the protective cover; 2), mounting a support base; 3), mounting the auxiliary rack; and 4), mounting the supporting protection device and the permanent magnet synchronous motor. According to the supporting protection device disclosed by the invention, blocking protection of the permanent magnet synchronous motor can be realized, and indirect mounting positioning between the permanent magnet synchronous motorand the equipment is also realized, so that mechanical vibration and noise of the permanent magnet synchronous motor in practical use can be effectively reduced, and meanwhile, a mode of the protective cover of the supporting protection device can be changed according to different use environments and places of the permanent magnet synchronous motor, and thus, the permanent magnet synchronous motor can be applied to multiple different using environments.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet synchronous motors, and in particular relates to a support protection device for permanent magnet synchronous motors and an installation method 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 this time, the kinetic energy of the rotor is converted into electric energy, and the permanent magnet synchronous motor is used as a generator; in addition, when the three-phase symmetrical current is passed into the stator side, since the three-phase stators have a difference of 120 in space, the three-phase stator currents rotate in...
