Description

一种定子组件及其应用的外转子电机A stator assembly and an outer rotor motor using the same

技术领域:Technical field:

本实用新型涉及一种定子组件及其应用的外转子电机。The utility model relates to a stator assembly and an outer rotor motor applied thereto.

背景技术:Background technique:

现有的电机多为二极电机,由于电机本身体积更小,绕线定子的端高偏高的问题更加明显。若继续沿用现有放置温控器的方式,既定子绕完副线绕组后,放置温控器,然后再绕主线,将温控器挤压包裹在主副绕组之间,之后再对绕线定子进行整形,只能使用较小的压力,若压力较大可能会对温控器造成不可逆的损伤;若使用较小压力整形,则整形效果不明显,不能有效降低绕组端高。这样无形中增加了定子组件的端高,不利于节省电机结构空间。且绕完副线再用相间绝缘胶带固定温控器,之后再绕线,温控器的固定不是很牢固,绕线的过程可能会因受力而发生移动。Most of the existing motors are two-pole motors. Due to the smaller size of the motor itself, the problem of the high end height of the wound stator is more obvious. If you continue to use the existing method of placing the thermostat, after the stator is wound around the secondary wire, place the thermostat, then wind the main wire, squeeze the thermostat between the main and secondary windings, and then wind the wire. For shaping the stator, only a small pressure can be used. If the pressure is large, it may cause irreversible damage to the thermostat; if a small pressure is used for shaping, the shaping effect is not obvious, and the winding end height cannot be effectively reduced. This virtually increases the end height of the stator assembly, which is not conducive to saving the structural space of the motor. And after winding the auxiliary wire, fix the thermostat with interphase insulating tape, and then rewind the wire. The fixing of the thermostat is not very firm, and the winding process may move due to force.

为了解决极数较少的电机绕组端高问题,及机绕线过程中如何放置固定温控器的问题,特此设计出一种新的风车片结构,这种新的方案既能有效地降低定子绕组的端高,又避免了绕线的过程中需要放置固定温控器的工艺操作困难。In order to solve the problem of the height of the winding end of the motor with a small number of poles, and the problem of how to place the fixed thermostat during the winding process of the machine, a new windmill structure is designed. This new solution can effectively reduce the stator The high end of the winding also avoids the technical difficulty of placing a fixed thermostat during the winding process.
