Problems solved by technology

[0006] In order to meet the miniaturization of the motor, the inner diameter of the through hole cannot be enlarged arbitrarily, resulting in corresponding restrictions on the size of the bearing and the rotating shaft accommodated in the bearing seat
Therefore, it is impossible to achieve a larger size of the bearing and the rotating shaft, resulting in a smaller size of the upper end, the bearing seat and the rotating shaft, and weak impact resistance

Abstract

The invention discloses a motor manufacturing method which comprises the following steps that a mounting seat is provided and comprises a support part and a bearing seat, the bearing seat and the support part are separated, the bearing seat comprises a connecting portion and an upper end portion connected with the connecting portion, and the upper end portion is away from the support portion. A hollow stator is provided and arranged on the bearing seat in a sleeved mode in the direction from the connecting portion to the upper end portion, and the bearing seat provided with the stator is connected with the support part. The stator is arranged on the bearing seat in the sleeved mode in the direction from the connecting portion to the upper end portion, so that motor manufacturing is facilitated, and cost is low.

Description

technical field [0001] The invention relates to the technical field of aircraft power devices, in particular to a method for manufacturing a motor. Background technique [0002] With the development of new permanent magnet materials, microelectronics technology, automatic control technology and power electronics technology, motors have made great progress. The motor uses electronic commutation to replace the traditional mechanical commutation. With its advantages of reliable performance, no wear, low failure rate, small size and high efficiency, it has gradually developed from the initial military field to the aerospace field. [0003] The aircraft is capable of vertical take-off and landing, stable hovering and autonomous cruising, and is suitable for police surveillance, news photography, fire command, traffic management, geological disaster investigation and pipeline cruising to realize real-time mobile surveillance in the air. At present, the power of the aircraft is re...
