[0004] In order to ensure the performance of the permanent magnet DC motor, the general permanent magnet DC motor is heavy, which is not conducive to the carrying and transportation of various electronic equipment or appliances. When the size is reduced, the rotor balance is not good, the motor noise is large, and the overall performance will be lower. affected

Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other ...

The invention discloses a micro direct-current motor winding structure. The micro direct-current motor winding structure comprises a commutator, a number of iron cores and a wire; the commutator comprises a number of winding parts, and the commutator is buckled on the number of iron cores; the number of poles of the iron cores is the same as the number of the winding parts and the number is an even number; the wire is winded around the number of winding parts and the number of iron cores to form a line package; and the wire is winded around two winding parts and two iron cores successively when winding, and the wire is winded around all the winding parts and all the iron cores until the end is fixed to a winding part in the order. According to the invention, if the wire is winded according to the above rules, then the balance of the rotor is improved, the noise and vibration are reduced, and the performance of the micro direct-current motor is improved.
Description
technical field [0001] The invention relates to a DC motor, in particular to a winding structure of a miniature DC motor. Background technique [0002] At present, the permanent magnet DC motor is a kind of DC motor that uses permanent magnets to establish a magnetic field. Due to the traditional structure and winding method, the wires are hypertrophied and squeezed each other, resulting in poor dynamic balance of the rotor, affecting performance and noise; using new The winding structure can reduce the balance of the rotor, and can realize the characteristics of low noise and low vibration. It is mostly used in various portable electronic devices or appliances, such as automotive electrical equipment, etc., especially automotive air-conditioning actuators that require motor drive. field. [0003] However, existing DC motors have the following drawbacks: [0004] In order to ensure the performance of the permanent magnet DC motor, the general permanent magnet DC motor is h...
