Embodiment

[0032] figure 1 The tool structure of the present invention is illustrated. As shown in the figure, a tool used in a permanent magnet synchronous motor assembly method includes: a main body steel plate 1 , a stainless steel bolt 2 , and a bolt positioning steel plate 3 .

[0033] A three-phase permanent magnet synchronous motor assembly method, the tool part used comprises: a main body steel plate 1, a stainless steel bolt 2, a bolt positioning steel plate 3; the main body steel plate is composed of a circular steel plate with a diameter of ФD and a circular steel plate with a diameter of Фd removed ; The stainless steel bolts are composed of M18*160 stainless steel bolts; the bolt positioning steel plate is welded by a steel plate with a length of 200mm and a width of 65mm.

[0034] (1) Main steel plate: used to fix the bolt to locate the steel plate. Because the permanent magnet synchronous motor shaft protrudes from the motor end caps at both ends for a certain distance, i...

Abstract

The invention discloses a method for assembling a three-phase permanent magnet synchronous motor. The permanent magnet synchronous motor is placed on the inspection platform prepared in advance, and the motor end cover is placed on the bearings at both ends of the motor. The tool is placed on the outer casing of the stator at both ends of the permanent magnet synchronous motor by manpower, and a set of bolts stand against the motor end cover. around the motor stator, another set of bolts against the motor stator; use a wrench to adjust the bolts to make the motor end cover coincide with the concentricity of the motor stator; use a wrench to twist the motor end cover bolts until the end cover is completely inserted into the motor stator housing superior. After the installation is in place, remove the device, symmetrically tighten the bolts around the motor end cover, and the motor assembly is completed. It is proved by practical use that the method of the present invention achieves the intended purpose, and is especially suitable for the assembly of the end cover of the permanent magnet synchronous motor.

Description

technical field [0001] The invention relates to a simple and quick assembly method of a three-phase permanent magnet synchronous motor, and the permanent magnet synchronous motor can be assembled lightly and quickly by using the device. Background technique [0002] Three-phase permanent magnet synchronous motor refers to a synchronous motor whose excitation system contains one or more permanent magnets. In recent years, permanent magnet synchronous motors have developed rapidly. They have the characteristics of high power factor, small size, high power density, large starting torque, low noise, low temperature rise and high reliability. They have gradually replaced the most commonly used AC in many occasions. Asynchronous motor. [0003] At present, most of the flotation motors in a concentrator are three-phase permanent magnet synchronous motors. To ensure the long-term stable operation of the motors, it is necessary to regularly add lubricating oil and replace bearings. ...
