Description

Technical Field

[0001] The utility model relates to the technical field of motors, and particularly relates to a motor. Background Art

[0002] At present, the stator assemblies of most motors are produced by winding copper wires, and the copper wires have good toughness. However, with the development of the market, motor products are diversified, and there is a demand for copper-clad aluminum wire motors with low cost.

[0003] For some motors with low-cost copper-clad aluminum wires, although the copper-clad aluminum wires achieve low cost, the copper-clad aluminum wires are relatively brittle and have few bending resistance times; when the current motors use copper-clad aluminum wires, wire breakage abnormalities are likely to occur. Summary of the Utility Model

[0004] The utility model mainly solves the technical problems that the copper-clad aluminum wires of the motors with low-cost copper-clad aluminum wires in the prior art are relatively brittle, have few bending resistance times, and are prone to wire breakage, and proposes a motor to buffer and protect the copper-clad aluminum wires, improve the bending resistance times of the copper-clad aluminum wires, and improve the product quality.

[0008] The stator core has a plurality of tooth parts, and the coil is wound around the tooth parts;

[0009] The coil has lead wires axially left at the radial inner side close to the tooth parts, the lead wires are electrically connected to the circuit board, and the lead wires are fixed by an elastic material at the position close to the tooth parts.

[0010] Preferably, the material of the coil is aluminum wire or copper-clad aluminum wire.

[0011] Preferably, the circuit board is disc-shaped; the circuit board is provided with through holes for the lead wires to pass through, and the lead wires pass through the through holes and are connected to the circuit board.

[0012] Preferably, the lead wires are fixed to the circuit board on the side close to the tooth parts.

[0017] A motor provided by the utility model fixes an elastic material at the root of the lead wire of the coil of the copper-clad aluminum wire stator assembly. The elastic material plays a buffering and protecting role for the copper-clad aluminum wire, thereby increasing the number of times the copper-clad aluminum wire can withstand bending, enabling the production to proceed smoothly and improving the product quality at the same time. It prevents the breakage of the root of the lead wire during the operation process. Description of the Drawings
