Embodiment Construction

[0007] The present invention will be further described below in conjunction with accompanying drawings and examples. Such as figure 1 As shown, it includes 1: magnetic pole piece, 2: felt and insulating gasket, 3: support block, 4: nut, 5: thin nut, 6: screw rod, 7: magnetic pole coil, 8 support block facade, 9 support Block plane, 10 round holes.

[0008] During installation, first install two pairs of nuts 4 and thin nuts 5 to the middle position of the screw rod 6, and then push the two ends of the screw rod 6 into the circular holes 10 on the two support block facades 8 respectively. Adjust the direction of the support block 3 according to the angle, and the whole is pre-loaded into the angle space between two adjacent magnetic pole coils 7. The upper edge of the support block 3 withstands the lower edge of the magnetic pole shoe 1. Pad felt and insulating gasket 2 between the sides of the coil 7, adjust the nuts 4 at both ends to make the support block plane 9 closely c...

Abstract

The invention provides a novel pole coil fixing and supporting frame structure. The problem that a pole coil can generate harmful deformation during high-speed rotation is solved. The novel pole coilfixing and supporting frame structure has the advantages of the small size, the light weight, the self-fine-tuning angle, no need of secondary processing and the like, improves the assembly efficiency, and is widely applied to the field of high-speed synchronous motors.

Description

technical field [0001] The invention relates to a novel magnetic pole coil fixing support frame structure, which is used to prevent harmful deformation of the magnetic pole coil during high-speed rotation. Background technique [0002] During the high-speed rotation of the magnetic pole coil, the coil side will be deformed under the action of centrifugal force, which will cause the coil to be deformed and damaged, and even detach from the pole piece to cause sweeping. The existing coil fixing support frame is to place a solid alloy block according to the angle between two adjacent magnetic pole coils, and then fix the alloy block to the yoke with a screw, which is bulky, has a large amount of processing, and has large assembly errors. Secondary processing and assembly. Contents of the invention [0003] The invention provides a novel magnetic pole coil fixed support structure, which solves the problem of harmful deformation of the magnetic pole coil when it rotates at hig...
