Magnetic steel service life detection device

Abstract

The invention discloses a device for detecting the service life of magnetic steel, belongs to the technical field of detection equipment, and aims to solve the problems that a conventional detection mode adopts a counting type test method to cause relatively large errors, the detection time is long, and the detection of the service life of the magnetic steel is difficult to accurately measure. When an air cylinder of the magnetic force detection device pushes a convex sliding plate to move, an arc-shaped guide block can drive a detection cylinder to slide up and down, so that a plurality of magnetic steels can be driven to move up and down, magnetic field data changes can be detected at different positions among the plurality of layers of magnetic steels through a magnetic probe, and the service life can be calculated; the detection result is more accurate; the second motor drives the fan blades to rotate in the blade cover, heat dissipation treatment can be conducted on the heat conducting fins through the ventilation pipe, the heating device conducts heating treatment on the magnetic steel through the multiple heat conducting fins, and therefore the service life of the magnetic steel in different temperature environments is prolonged.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a magnetic steel life detection device. Background technique [0002] The magnetic properties of the motor magnets are effectively preserved for a long time, so they are used in the motor. The demagnetization of the motor is rare, usually because the motor is under high load for a long time. The existing magnet life test device, All magnets are fixed and installed, and more complex components are used to realize the corresponding test items. The tested magnets are tested one by one, and the test cycle is long. According to the loss of magnetic permeability of the magnets at a certain temperature, the magnets will produce Irreversible demagnetization, the method of counting test often has large errors, and it is difficult to accurately measure the life of the magnet. For this reason, we propose a device for detecting the life of the magnet to solve the above problems. ...
