Description

Technical Field

[0001] The utility model relates to the technical field of aluminum wire motors, in particular to a copper-aluminum connection structure for aluminum wire motors. Background Art

[0002] With the sharp rise in copper prices, cost pressures are increasing in the motor industry. However, since aluminum is less than half the price of copper and its weight is less than one-third of copper's, its cost advantage is significant, leading more and more motor manufacturers to begin producing aluminum motors. Due to the chemical and physical properties of aluminum enameled wire, the handling of its joints is crucial. To prevent electrochemical corrosion between the stripped aluminum wire and the copper material in air, which can lead to wire breakage, exposed aluminum wire or joints must be tightly sealed. This places higher demands on the internal structure and electrical connection methods of aluminum motors.

[0003] Existing aluminum wire motors generally have distributed windings with an inner rotor structure. The connection between the aluminum enameled wire of the stator and the power lead is generally made by crimping or welding the terminal and then wrapping it with heat shrink tubing. The winding and inserting speeds are slow and the production efficiency is low. The connection between the power lead and the aluminum enameled wire is not sealed to isolate the air, making the connection point prone to oxidation, resulting in power failure and a short lifespan. Therefore, a copper-aluminum connection structure for aluminum wire motors is proposed. Utility Model Content
