Embodiment Construction

[0029] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0030] The invention designs a motor stator polarity detection device. The device itself has a simple structure, and when the stator polarity is detected by using it, the operation is convenient. For a multi-slot stator, the stator polarity sequence can be evaluated at one time with high efficiency and accuracy.

[0031] The packaged shape of the motor stator polarity detection device in this embodiment is as follows: figure 1 As shown, it includes a housing 1 and a detection component 2 located inside the housing 1, wherein figure 1 It can be seen that the housing 1 of this embodiment is a ring-shaped closed housing, and a part of the detection device 2 is exposed along the outer circumference of the housing.

[0032] From figure 2 It can be seen that the detection component 2 of this embodiment includes a positioning seat 3, an elastic component 4, a magnetic po...

Abstract

The invention belongs to the field of permanent magnet motors, and relates to a stator armature polarity detection device, so the problems that an existing stator armature polarity detection method ishigh in cost, low in efficiency, complex in operation and the like are solved. The detection device comprises a shell and a detection part; the detection part comprises positioning seats, an elasticassembly, magnetic pole seats and magnetic poles. The positioning seats are uniformly distributed along the same circumference and are fixed in the shell; the included angle between the adjacent positioning seats is 60 degrees; the elastic assembly is fixed to the positioning seats, and the telescopic direction of the elastic assembly is the same as the radial direction of the shell. The magneticpole seats are fixed at the free end of the elastic assembly; the magnetic poles are fixed on the magnetic pole seats; the magnetisms of the two magnetic poles with the included angle of 180 degrees are opposite; the magnetisms of two adjacent magnetic poles are opposite; openings allowing the magnetic poles to pass through are formed in the portions, corresponding to the magnetic poles, of the shell, and the magnetic pole ends extend out of the openings. By utilizing the characteristics of the polarity of the stator, one-time detection of the polarity sequence of the motor stator can be realized without assembling a motor assembly, the detection process is simple, and the result is visual.

Description

Technical field [0001] The invention belongs to the field of permanent magnet motors, and specifically relates to a stator armature polarity detection device. Background technique [0002] The main structure of the permanent magnet motor includes the stator, rotor, brake, position sensor, etc. The production process is complicated, especially when the stator is produced, the stator needs to be offline and tied. Workers are easy to make mistakes during the offline and wire binding process. B and C phase sequence, the correctness of the stator winding phase sequence not only determines the rotation direction of the motor, but also directly affects the torque output capacity of the motor. If the A, B, and C phase sequence is wrong, the motor may not operate normally. Serious consequences such as burning the drive module. Therefore, it is necessary to check the phase sequence of the permanent magnet motor. Because the motor has a small air gap and the rotor has magnetic force, it i...
