Background
The tractor motor for automobile motor and elevator staircase requires small motor volume because of limited installation space and requires low vibration and low noise because of the use environment. In order to achieve high power density, concentrated windings are needed, and stator cores with segmented teeth are adopted. The existing process generally adopts an insulating framework structure, but the die cost of the insulating framework is very high, the investment is too large before the product is shaped, and the die is possibly scrapped and reopened due to the size adjustment of the product punching sheet. Therefore, there is a strong need to find a new insulation structure to replace it in the prototype.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the insulating skeleton texture of the general adoption of current technology, nevertheless the mould expense of insulating skeleton is very high, drops into too greatly before the product is stereotyped, also probably causes the mould to scrap the shortcoming of reopening because of product towards piece size adjustment, the to-be-solved technical problem of the utility model is to provide an insulation system for motor model machine trial-manufacturing with low costs, the stator blocking tooth that insulating nature is good.
The utility model is achieved by the following concrete technical means:
an insulation structure for trial production of a motor prototype of stator block teeth comprises the block teeth and an insulation plate; first guide angles are arranged on two sides of the upper end of each blocking tooth, second guide angles are arranged on two sides of the lower end of each blocking tooth, a conductor groove is formed by the first guide angles and the second guide angles in a combined mode, a clamping groove is formed in the first guide angle on one side, and a clamping block is arranged on the first guide angle on the other side; a through fixing hole is formed in the first guide corner, and a through fixing hole is also formed in the middle of the lower part of the blocking tooth; third guide angles are arranged on two sides of the upper end of the insulating plate, fourth guide angles are arranged on two sides of the lower end of the insulating plate, and avoidance grooves are formed by the combination of the third guide angles and the fourth guide angles; the insulating plate is glued to the end of the blocking tooth.
Furthermore, the top ends and the bottom ends of the blocking teeth and the insulating plate are arc-shaped.
Further, the fixing hole is rectangular.
Further, the height of the third chamfer is lower than that of the first chamfer.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a design an insulation board and insulate the tip of halving the tooth piece, simple and practical, convenient to use, high efficiency, safety can be used for the big motor of various needs power density, satisfy when the operation require vibration, the motor model machine trial-manufacturing of small in noise to simple manufacture can improve the speed of motor model machine trial-manufacturing greatly, reduces the manufacturing cost of product trial-manufacturing.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Examples
An insulation structure for trial production of a motor prototype of stator block teeth is shown in figures 1-3 and comprises block teeth 1 and an insulation plate 2; a first guide angle 101 is arranged on each of two sides of the upper end of each blocking tooth 1, a second guide angle 105 is arranged on each of two sides of the lower end of each blocking tooth 1, a conductor groove 106 is formed by combining the first guide angles 101 and the second guide angles 105, a clamping groove 102 is formed in the first guide angle 101 on one side, and a clamping block 103 is arranged on the first guide angle 101 on the other side; a through fixing hole 104 is formed in the first bevel 101, and a through fixing hole 104 is also formed in the middle of the lower part of the blocking tooth 1; third guide angles 201 are arranged on two sides of the upper end of the insulating plate 2, fourth guide angles 202 are arranged on two sides of the lower end of the insulating plate, and avoidance grooves 203 are formed by combining the third guide angles 201 and the fourth guide angles 202; the insulating plate 2 is glued to the end of the blocking tooth 1.
When a motor prototype is trial-manufactured, the tooth dividing block is fixed through the fixing hole 104, the insulating plate 2 is connected to the end of the tooth dividing block through glue, the glue has insulating property and can resist high temperature of more than 150 degrees, the metal part at the end is covered, the end of the tooth dividing block 1 is isolated from being conducted, and the clamping groove 102 at the first guide angle 101 is avoided, so that the insulating effect is achieved. After the block teeth 1 are wound with the coils, the insulating film material with certain thickness is used for winding the block teeth and the insulating plate 2 around the conductor groove 106 and the avoidance groove 203, so that the winding and the block teeth 1 form a whole, the situation that the conductor groove 106 in the groove forms current, the block teeth 1 and the conductor cannot form magnetic circuit conversion is avoided, and the electromagnetic force or motor vibration damage to the winding is avoided. The clamping grooves 102 on the first guide angles 101 and the clamping blocks 103 on the second guide angles 105 on the segment teeth 1 can be conveniently assembled by the plurality of segment teeth 1, and finally the stator of the motor is formed. The insulating plate 2 can be manufactured only by a single punching die which is simple to manufacture, the production cost of trial production of products can be reduced, the use is convenient and simple, and the trial production speed of a motor prototype can be greatly improved.
