Motor stator construction and manufacturing method thereof

Abstract

A motor stator structure comprises upper claw pole elements and lower claw pole elements arranged in pairs and a sleeve bearing, wherein each claw pole element includes a plurality of claw poles in staggered arrangement in the vertical direction; a gap is formed between adjacent claw poles; a hollow region capable of accommodating a rotor component is formed at the center of the upper claw pole elements and the lower claw pole elements; the upper claw pole elements and the lower claw pole elements are connected with the sleeve bearing through a fixing structure formed from a plastic material by integrated injection molding; the fixing structure includes a bottom plate formed on one end of the hollow region, a sheath extending from the center of the bottom plate, and a plastic material section filled in the gaps of the claw poles; and the sleeve bearing is embedded between the bottom plate and the sheath. The invention also provides a method for manufacturing the motor stator structure. By integrally forming and fixing the sleeve bearing and integrally forming the sheath for supporting the rotor component, the motor stator structure has the advantages of simplifying assembly process, ensuring high concentricity of each element and improving operation reliability.

Description

technical field [0001] The invention relates to a motor, in particular to a motor stator structure applied to electronic products and a manufacturing method thereof. Background technique [0002] Whether in manufacturing equipment or various instruments in daily life or in the field of science and technology, motors usually play an extremely important role. For example, in the industry, the devices that drive large turbines or drive peripheral components of computers need to be completed by motors. With the continuous development of technology and modern industry, motors are widely used in portable digital cameras, camera phones and other product fields. In order to adapt to the increasingly miniaturized development requirements of these electronic products, it is usually necessary to make some design improvements to the structure of the motor. The stepper motor is often used in these miniaturized electronic products because of its characteristic of easy control of the outp...

AI Technical Summary

Problems solved by technology

[0004] When the stator structure of the above-mentioned stepping motor is assembled, the bearing needs to be assembled into the shaft seat at the bottom of the pole claw element, and the bushing must be assembled separately, resulting in cumbersome motor stator assembly process

At the same time, due to the large number of components, it is difficult to ensure the concentric arrangement of the claw components, bushings and bearings in the stator structure, thereby affecting the working efficiency of the stator structure, and cannot guarantee the stability of the working performance when it is assembled with the rotor components and operated.
