Why are copper winding motors better than aluminum winding motors?

There are significant differences between aluminum wire motors and copper wire motors in the materials, performance and price of car wash machines:

Material composition

Copper wire motors: The coils of the stator and rotor are copper.

Aluminum wire motors: the stator coil material is aluminum, and the rotor coil part is copper.

Performance performance

Conductivity: Copper conductivity is better than aluminum, and at the same power, aluminum wire motors require a greater current, which may lead to slightly lower efficiency.

Heat dissipation: The thermal conductivity of copper is better, the motor produces less heat when it is operating, and the heat is dissipated quickly, reducing the risk of damage due to overheating.

Overload capacity: Copper wire motors perform more stable when overloaded, while aluminum wire motors are prone to overheating affecting performance.

Endurance: Copper has a higher melting point than aluminum, and copper wire motors are more resistant to high temperatures and usually have a longer life.

Price difference

The price of copper wire motors is usually higher than that of aluminum wire motors due to the high cost of the material.

Buying Advice

If the budget is sufficient and the requirements for performance and durability are high, it is recommended to choose a copper wire motor; If the budget is limited and the frequency of use is low, aluminum wire motors are also a good choice.

How to distinguish

1. Look at the motor's appearance labels. The word "pure copper" is usually a copper wire motor.

2. Observe the coil color: The copper wire is orange, the aluminum wire is dark red, and it is the copper wire that does not change color after being scraped.

3. Weight: Under the same volume, copper wire motors are heavier because of the greater weight of copper.
