Problems solved by technology

The deficiencies of the above-mentioned motors are as follows: 1. Installing slot insulation in the stator slots and setting frames at both ends of the stator core will make the manufacture and maintenance of the motor inconvenient; 2. When stamping the stator core unit, it will cause material damage. Low utilization rate and more waste; 3. The winding efficiency of the wire embedding machine is low; 4. The wire embedding machine has high requirements for the dimensional accuracy of the stator slot, slot insulation, and skeleton during winding; 5. The utilization rate of dipping paint is low , inconvenient operation; 6. Inconvenient maintenance

Embodiment 1

[0052] Such as Figure 4 As shown, the skeleton unit 31 has an integral structure, the tooth part 2 and the yoke part 1 are detachably connected, and the tooth part 2 passes through the inner hole of the skeleton unit 31 to form a tooth part assembly. In the tooth assembly, the positioning portion 211 of the tooth portion 2 protrudes from the tubular structure 311 of the skeleton unit 31, and the tooth assembly inserts the positioning portion 211 into the groove 121 of the yoke 1 Position the tooth part assembly on the yoke part 1, and then connect the tooth part 2 and the yoke part 1 through a fastener 4, so that the tooth part 2 is connected to the yoke part 1 .

[0053] In this embodiment, the tooth part 2 in the tooth part assembly is installed on the winding equipment, and the winding 5 is completed by the rotation of the tooth part assembly. In this way, the wire inserting machine can be omitted, and the winding for distributed winding can be used directly. The thread ...

Embodiment 2

[0055] Such as Figure 5-Figure 8 As shown, the skeleton unit 31 is a split structure, the skeleton unit 31 includes a first part 32 and a second part 33, and the first part 32 and the second part 33 are along the axial direction of the yoke 1 The skeleton unit 3 in the first embodiment is divided into two parts, and the two parts are butted to form a skeleton unit 31. At this time, the yoke 1 and the tooth 2 can be integrally formed or detachably connected. The frame unit 31 can insert the first part 32 and the second part 33 into the tooth part from both ends of the tooth part 2 after the yoke part 1 and the tooth part 2 are connected. 2, of course, the first part 32 and the second part 33 can also be assembled into the skeleton unit 31 first, and then the skeleton unit 31 and the tooth part 2 can be assembled into the tooth part assembly, Finally, the tooth assembly is connected with the yoke 1 .

Embodiment 3

[0057] Such as Figure 9 and Figure 10 As shown, the skeleton unit 31 is a split structure, the skeleton unit 31 includes a third part 34 and a fourth part 35, the third part 34 and the fourth part 35 are along the yoke 1 Divide the skeleton unit in the first embodiment radially into two parts close to and away from the yoke 1, at this time, the teeth 2 and the yoke 1 are detachably connected, preferably, the third The part 34 and the fourth part 35 are assembled into the skeleton unit 31, and then the skeleton unit 31 and the tooth part 2 are assembled into a tooth part assembly, and finally the tooth part assembly is connected to the yoke part 1 .

[0058] In this embodiment, the winding 5 can be wound directly through a mold, and then dipped in paint to shape, and then the winding 5 is passed on the fourth part 35, and then the third part 34 and the fourth part 35 are assembled into the described Skeleton unit 31.

Abstract

The invention discloses a motor. The motor comprises a stator and a rotor; the stator comprises a yoke part and multiple circumferentially arranged teeth parts; the motor further comprises an insulation skeleton, the insulation skeleton comprises multiple skeleton units circumferentially arranged and matched with multiple teeth parts; the skeleton units and the yoke part are in detachable connection. By arranging multiple skeleton units cooperated with the teeth parts, so that the teeth part is insulated from the winding arranged on the teeth part, the motor is convenient for assembling in themanufacturing by arranging the skeleton units and the yoke part as the detachable connection, and the dismounting and maintenance are convenient in the later maintenance.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor. Background technique [0002] At present, in the motors of the prior art, the stator includes a stator core and a skeleton arranged at both ends of the stator core. The stator core includes a yoke and teeth, and a stator slot is formed between every two adjacent teeth. The stator also includes The slot insulation is set in the stator slot. The stator core is formed by stacking and fixing multiple silicon steel sheets. The silicon steel sheet is punched by a punching machine into a stator core unit including teeth and yokes; One turn, the winding mouth of the wire inserting machine passes through the stator slot twice for each turn. The deficiencies of the above-mentioned motors are as follows: 1. It is inconvenient to make and maintain the motor if the slot insulation is provided in the stator slots and the skeleton is provided at both ends of the stator core; 2. When st...
