Explosion-proof motor manufacturer: The difference in materials between aluminum and copper motors
Explosion-proof motor manufacturers tell everyone that, at the industrial level, in most cases, motors using copper wire and aluminum wire are more common. Other metal motors will not be discussed here. In explosion-proof motors, cast iron casings with copper wire motors are basically used, while most manufacturers of ordinary motors choose aluminum casings and aluminum motors.
Explosion-proof motor manufacturer Let's talk about the difference between copper wire and aluminum wire:
I. Different metal densities:
The density of copper is 8.9*10 cubic kilograms/cubic meter.
The density of aluminum is 2.7*10 cubic kilograms/cubic meter.
The density of copper is almost three times that of aluminum. With the same number of metal coils, the weight of an aluminum motor is far less than that of a copper wire motor, but copper wire motors are superior to aluminum wire motors in terms of wire performance and service life.
II. Production:
In the production process, the aluminum wire on the motor winding is brittle, has low toughness, and is easily broken.
Copper wire is pressed or drawn wire:
a. Good conductivity, often used to manufacture wires, cables, brushes, etc.
b. Copper wire also has good thermal conductivity and is used to manufacture magnetic instruments and meters that need to prevent magnetic interference, such as compasses and aviation instruments.
c. Copper wire has good plasticity and is easy to process by hot pressing and cold pressing. The mechanical properties of copper wire are very good, with an elongation of 30 and a tensile strength of 315.
Therefore, in motors with the same thickness and number of turns, the pass rate of copper wire is about twice that of aluminum wire.
III. Current carrying capacity
For example, if the number of coils of the same size is 5 A, then the current carrying capacity of copper wire is at least 6 A, and aluminum motors are prone to overheating after long working hours, causing motor damage, such as boiling the plastic glue on the outer packaging.
Copper wire is not like that; its performance is stable, and it can run for a long time.
IV. Price
In fact, the price of aluminum motors is undoubtedly cheaper. Because of this, in some price wars, the price of aluminum motors can be more than twice as cheap as copper wire motors, which also leads to a large number of purchases by mid-to-low-end consumers.
Therefore, when choosing a motor, Explosion-proof motor manufacturer It is recommended to choose a copper wire motor, and a pure copper wire motor. Some factories, in order to save costs, often use copper-clad aluminum wire motors, leading customers to mistakenly believe that they are copper wire motors. This saves money compared to pure copper wire motors, but those who buy cheap often end up losing out.
