AI Technical Summary

Technical Problem

The existing assembly mode of single-phase asynchronous motors results in low coaxiality between the stator and rotor, leading to a large air gap and inefficient use of electromagnetic materials, increasing manufacturing costs.

Method used

A motor assembly structure featuring a stator with middle and side iron cores, where the first end cap has an inner arc surface in interference fit with the first side iron core's outer arc surface, and the second end cap has an inner arc surface in clearance fit with the second side iron core's outer arc surface, enhancing coaxiality and reducing the air gap through precise positioning fits.

Benefits of technology

This configuration improves the coaxiality of the stator and rotor, reduces the air gap, and enhances electromagnetic efficiency by optimizing the use of materials, leading to a more stable and efficient motor performance.

Abstract

A motor and an assembly structure thereof, a motor assembly mechanism comprises a stator (1), a first end cap (2), a second end cap (3) and a fastener (4) for fastening the stator (1), the first end cap (2) and the second end cap (3), wherein the stator (1) comprises a middle iron core (13), a first side iron core (11) and a second side iron core (12), the inner edge of the first end cap (2) is provided with a first inner arc surface (21), the outer edge of the first side iron core (11) is provided with a first outer arc surface (111) in interference fit with the first inner arc surface (21), the inner edge of the second end cap (3) is provided with a second inner arc surface (31), and the outer edge of the second side iron core (12) is provided with a second outer arc surface (121) in clearance fit with the second inner arc surface (31). Through the positioning cooperation of the first side iron core (11) and the first end cap (2) and the positioning cooperation of the second side iron core (12) and the second end cap (3), the motor and the assembly structure thereof provided by the present application can effectively improve the coaxiality of the stator and the end caps, and thus improve the coaxiality of the stator and a rotor, and reduce the air gap between the rotor and the stator.
