Problems solved by technology

These methods have the following problems: 1. Increasing the weight of copper wires and the number of motors will increase the cost, which cannot achieve the purpose of saving costs and improving efficiency; 2. Designing the screws outside the box makes the appearance of the original product completely It can no longer be regarded as a product of the same model, resulting in lower market acceptance of the appearance

Embodiment 1

[0023] Such as figure 2 The high-power motor shown includes a cylindrical casing 1, the inner wall of the casing 1 has several evenly distributed winding slots 2, and at least four groups of evenly distributed electromagnetic coils are wound in the several winding slots 2, There are several screw holes 3 extending along its length direction on the casing 1, and several screw holes 3 are evenly distributed along the central axis of the casing 1, and each screw hole 3 is set corresponding to an electromagnetic coil, and the number of electromagnetic coils is the screw hole Integer multiples of 3, the magnetic force line 4 generated by the electromagnetic coil intersects the corresponding screw hole 3, such as image 3 As shown, its intersecting area is less than or equal to 10% of the total area of ​​the screw holes 3.

[0024] Such as figure 2 As shown, the number of electromagnetic coils is twice the number of screw holes 3, there are eight sets of electromagnetic coils, a...

Embodiment 2

[0027] The structural principle of this embodiment is basically the same as the structural principle of Embodiment 1, the difference is that the number of electromagnetic coils is 1 times the number of screw holes 3, there are four groups of electromagnetic coils, and the number of screw holes 3 is four and is the same as that of the electromagnetic coils. One-to-one correspondence settings.

Embodiment 3

[0029] The structural principle of this embodiment is basically the same as the structural principle of Embodiment 1, the difference is that the number of electromagnetic coils is 1 times the number of screw holes 3, there are eight groups of electromagnetic coils, and the number of screw holes 3 is eight and the same as that of the electromagnetic coils. One-to-one correspondence settings.

Abstract

The invention provides a high-power motor, and belongs to the technical field of motors. The high-power motor provided by the invention solves a problem that the motor is caused to be higher in power,more in consumed electric energy, greater in heat generation and higher in energy consumption because electromagnetic lines of force of the existing motor coils completely cover screw holes. The high-power motor comprises a cylindrical shell, wherein the inner wall of the shell is provided with a plurality of uniformly distributed winding slots, the plurality of winding slots are internally woundwith at least four groups of uniformly distributed electromagnetic coils, the shell is provided with a plurality of screws holes extending along the length direction, the plurality of screw holes areuniformly distributed along a central axis of the shell, each screw hole is arranged in a mode of corresponding to one electromagnetic coil, the number of the electromagnetic coils is an integral multiple of the number of the screw holes, magnetic lines of force generated by the electromagnetic coils are intersected with the corresponding screw holes, and the intersection area is less than or equal to 10% of the total area of the screw holes. The high-power motor has the advantages of high working efficiency, low energy consumption, low motor heat generation and the like.

Description

technical field [0001] The invention belongs to the technical field of motors and relates to a high-efficiency motor. Background technique [0002] The structure of the existing motor is as figure 1 As shown, it includes a cylindrical motor casing 1, and a number of winding slots 2 for winding copper wires are evenly provided on the inner wall of the casing 1, and are uniformly arranged on the motor casing 1 along the central axis of the casing 1. Several screw holes 3 are provided, and the several screw holes 3 extend along the axial direction of the casing 1 . Since the screw hole 3 is closer to the winding groove 2, such as figure 1 As shown, the electromagnetic field lines 4 of a group of coils arranged opposite to the screw hole 3 completely cover the screw hole 3, and the electromagnetic force is a small part of the screw hole 3 and the bolt inserted into the screw hole 3, which is required for the operation of the compressor. If the force remains the same, the moto...
