Problems solved by technology

[0002] The iron core assembly of the disc motor is generally composed of a plurality of iron cores distributed along the circumferential direction, and the accuracy of the angle between adjacent iron cores is relatively high. After the housing is positioned, it is fixed with glue. The coil inside the iron core needs to be wound and shaped and covered with insulating tape on the outside. The process is complicated. At the same time, the heat emitted by the motor will heat the glue and heat The glue is easy to age and soften, which makes the angle between the iron cores change and affects the normal operation of the motor

Abstract

The invention relates to a motor skeleton and a disc motor adopting the motor skeleton, comprising: a stator core skeleton and an end cover iron core skeleton; the stator core skeleton includes a plurality of sector blocks arranged along the circumferential direction, and the outer ends There are slots on the edge for connecting adjacent sectors, and the grooves in the slots match the shape of the gap between adjacent sectors, and multiple stator cores are suitable for loading into the above-mentioned stator core frame to form a stator Iron core assembly; the end cover iron core skeleton includes a plurality of sectors arranged in the circumferential direction, the inner ends of each sector are connected as a whole, and the multiple end cover iron cores are suitable for fitting into the gaps between adjacent sectors. End cover core assembly; compared with the way of fixing with glue, it can ensure that the angle between the stator cores and the end cover cores remains unchanged for a long time.

Description

technical field [0001] The invention relates to a motor skeleton and a disc motor adopting the motor skeleton, which can keep the position of the iron core of the motor fixed. Background technique [0002] The iron core assembly of the disc motor is generally composed of a plurality of iron cores distributed along the circumferential direction, and the accuracy of the angle between adjacent iron cores is relatively high. After the housing is positioned, it is fixed with glue. The coil inside the iron core needs to be wound and shaped and covered with insulating tape on the outside. The process is complicated. At the same time, the heat emitted by the motor will heat the glue and heat The glue is easy to age and soften, which will change the angle between the iron cores and affect the normal operation of the motor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a motor frame capable of supporting the iron cores ...
