のである。(Problems to be Solved by the Invention) However, the method of insulating the motor core, the resin or powder coating method in (1), depends on the amount of mixed resin and powder to be sprayed, the concentration of liquid, and the amount of spraying. There is also the problem that it takes a lot of man-hours to control the drying temperature, drying time, etc. Furthermore, the method (2) of inserting resin caps from both sides of the motor core to insulate the core When the throttle is straight, it is possible to insert a resin cap with a wall thickness of 1 or more.However, in a skew type motor core where the core is laminated at an angle, the groove of the cap made of phenol resin or melamine resin is inserted into the core. Since the yoke of the cap is slanted, it is difficult to insert the cap, and there is a risk of the cap breaking if the cap is inserted forcefully.Furthermore, the cap is molded from resin so that the groove portion thereof has an inclination angle with respect to the center line. The problem is that it cannot be molded due to undercuts.

ることを技術的課題とするものである。The present invention relates to the insulation of a skew-type motor core in which the motor core part has a sloped shape.Instead of spraying the material to be insulated, the present invention proposes a resin that can be insulated by fitting the groove of a cap made of insulating resin into the yoke of the core. The technical problem is to provide a cap made of aluminum.

In other words, in a skew type motor in which cores are diagonally stacked, the resin cap, which has a large number of radial grooves that fit into the yoke portion of the core, is formed from both end surfaces of the stacked cores and is made of polyamide or polyamide with glass fiber. 5 to 20% by weight and molded into one piece, and the thickness of the resin cap is 11 cm or less, and this resin cap is fitted to the core to form the insulating part of the skew type motor core. It is.

とができる。(Operation) The technical means operates as follows. In other words, a resin cap made of polyamide resin or polyamide resin mixed with glass fiber has excellent heat resistance and a high heat deformation temperature, and is extremely flexible when the wall thickness is 1 mm or less, making it suitable for use on skew-type motor cores. It can be easily inserted into the throttle by pushing it forcefully by hand. In this case, strong press-fitting by a jig or cracking or cracking of the resin due to press-fitting will not occur at all. Glass fiber content is 5-20% by weight
is appropriate, and the resin wall thickness can be reduced to about 0.5 W.

Glass fibers having a length of 0 μm and 5 fins or less may be mixed in an amount of 5 to 20% by weight, and by blending glass fibers, the thickness can be further reduced. To explain the method of inserting the cap 5 into the motor core 1 with reference to FIG. 3, the cores are shifted and stacked in an inclined manner as shown in FIG. Insert caps 5a and 5b (indicated by chain lines) from both sides of the motor core. In this case, if the grooves 6a, 6b, . . . of the cap are aligned with the yoke direction of the core and the cap is firmly inserted, the cap will fit into the core. Third
Figure (c) shows a skew type core with caps inserted from both sides.
