Problems solved by technology

However, the stator of the motor, especially the stator of the motor in the blower, is currently grounded mainly through wire welding. On the one hand, this grounding method is prone to failure due to the violent vibration of the motor during operation, and on the other hand, it is not conducive to the assembly operation of the motor.

Abstract

Disclosed is an electric machine (2), comprising: a stator (21) including a stator core (211), and a rotor (22); and a grounding pin (5) which is at least used for realizing grounding connection of the stator core (211), wherein the grounding pin (5) is configured to be electrically connected with the stator iron core (211) by being partially embedded into the stator iron core (211). An electric device, in particular a blower (1), comprising the electric machine (2) is also disclosed. According to the invention, the grounding mode is simple and reliable, and the assembly is convenient.

Description

technical field [0001] The invention relates to an electric machine and an electric device, in particular a blower, comprising such an electric machine. Background technique [0002] The motor has many advantages such as convenient control and simple structure, and is currently widely used in many fields, such as blowers. [0003] However, as an electromagnetic device that realizes electric energy conversion or transmission based on the law of electromagnetic induction, the problem of electromagnetic compatibility needs to be considered. Electromagnetic compatibility refers to the ability of a device or system to operate in accordance with the requirements in an electromagnetic environment without causing unbearable electromagnetic disturbance to any device in its environment. [0004] It is for reasons of electromagnetic compatibility that the stator of the motor needs to be grounded, eg connected to a conductive housing. However, the stator of the motor, especially the s...
