Problems solved by technology

[0003] However, although the stator of the above-mentioned existing motor can be electrically connected to the circuit board through the pins, when the motor is started, due to the large starting torque, the pins are likely to be unstable, resulting in loosening of the stator. In severe cases, it will cause the problem of poor electrical connection of the pin, which will affect the performance and service life of the motor

Abstract

The invention provides a motor stator and the objective of the invention is to solve the problem that a stator is easy to loosen when an existing motor is started. The motor stator comprises a base provided with at least one positioning hole located in the periphery of a coupling part; and a winding group which is provided with a magnetic pole piece combined with an insulating piece, wherein a coil is wound on the insulating piece, at least one positioning convex column is connected with the insulating piece, the positioning convex columns are arranged in the positioning holes in a penetratingmanner, and the positioning convex columns are not electrically connected with the coil; and an elastic binding sleeve piece which is sleeved in the positioning convex columns and is propped againstthe inner walls of the positioning holes.

Description

technical field [0001] The invention relates to a motor stator, in particular to a motor stator capable of preventing the stator from loosening. Background technique [0002] Existing motors have a stator coupled to a base, the stator has an iron core wound with a coil, a pin of the stator is coupled to a circuit board through a hole in the base, and the pin is electrically connected to a circuit board. A rotor rotatably couples the stator with the coil and the circuit board. In this way, the coil can drive the rotor to rotate relative to the stator after the coil is energized, and an embodiment similar to the conventional motor has been disclosed in the patent case of Chinese Publication No. 1409888 "External Rotor Brushless DC Motor". [0003] However, although the stator of the above-mentioned existing motor can be electrically connected to the circuit board through the pins, when the motor is started, due to the large starting torque, the pins are likely to be unstable,...
