Abstract

The invention discloses a method and a device for bonding magnetic steel of an external rotor duplex magnetoelectric machine. The method comprises the following steps of: firstly manufacturing positioning holes corresponding one by one on two end faces of a shell; manufacturing two same arc clamping boards provided with positioning slots; fixing the arc clamping boards on the two end faces of theshell; clamping and fixing one positioning plate in the positioning slots on the same axis; sticking insulation bars by attaching both sides of the positioning plate; repeating the steps like this toevenly stick the insulation bars on the inner circle surface of the shell according to the requirements; and finally, sticking the blocky magnetic steel on the inner circle surface of the shell alongthe slot of each two insulation bars. The device has simple structure, and the magnetic steel bonding method has simple operation so as to greatly improve the working efficiency of bonding the magnetic steel and reduce the labor intensity of workers. In addition, the method and the device use an over-positioning principle, greatly improve the accuracy of mounting the magnetic steel, effectively ensure the product quality, and improve the economic benefit of external rotor magnetoelectric machine manufacturers.

Description

Technical field: [0001] The invention relates to a magnetic steel bonding method and device for an outer rotor compound permanent magnet motor, and belongs to the technical field of magnetic steel bonding for an outer rotor compound permanent magnet motor. Background technique: [0002] With the development of electronic and mechanical technology, the application range of outer rotor compound permanent magnet motors is becoming wider and wider. At present, when manufacturing the rotor of the outer rotor compound permanent magnet motor, in order to reduce the fluctuation of the rotating torque, the magnetic steel is usually installed at a certain angle relative to the axial direction. But existing technology mainly is to adopt T-square or the marking board and positioning slot with unilateral positioning to draw lines manually one by one, and then paste the method of insulating strip and magnetic steel. The work efficiency of this method is low, the accuracy of magnetic stee...
