Mix motor

Motors can be classified into different types based on the material of the coil, such as copper or aluminum. The most common type of motor coil is made of purple copper, with an outer layer of insulating paint. However, some low-end motors may use aluminum wire with a layer of paint.
Motors can also be classified based on the material of the outer casing, such as aluminum or iron. Aluminum-cased motors can be disassembled to obtain about 7% of the broken aluminum casing, which can be sold as a relatively clean raw material. The price of aluminum-cased motors is generally higher than that of iron-cased motors.
Motors can also be classified based on the type of energy used, such as alternating current (AC) or direct current (DC). DC motors have a higher copper content than AC motors due to the presence of a commutator. AC motors are commonly used in large equipment and industrial settings.

Motors are widely used in various agricultural, industrial, and domestic environments, and the output of motor scrap is closely related to population density and industrial distribution. Globally, the main producers of motor scrap are the United States, Europe, Japan, South Korea, and Australia. Due to the high labor costs required to process motor scrap, these countries mainly export their motor scrap.

Mixed motors are composed of different sizes and specifications of motors. The copper content of motors varies depending on the size, with smaller motors generally having a higher copper content. The copper content of small, medium, and large motors decreases in that order. The value of mixed motors is generally higher when there are more small motors.

The processing of motor scrap mainly involves mechanical crushing and manual disassembly. The first step is to remove the outer casing, which can be done mechanically or manually. The second step is to separate the stator and rotor and remove the coil. The coil can be processed further depending on the requirements of the buyer.

The detection of motor scrap mainly involves checking whether the coil is made of copper or aluminum. This can be done by partially or completely disassembling the motor and inspecting the coil. Buyers and sellers should avoid misidentifying aluminum motors as copper motors, as this can lead to disputes.

The processing of motor scrap requires a high degree of manual labor, and the importation of motor scrap is strictly regulated in many countries. Therefore, the disassembly of motor scrap is mainly done in countries such as Thailand, Malaysia, Pakistan, and India, where labor costs are low and import regulations are more relaxed.

When purchasing motor scrap, it is essential to pay attention to the authenticity of the pictures provided by the seller. The buyer should request detailed and accurate pictures of the motor scrap to ensure that the goods match the description. It is also crucial to check the material of the coil, whether it is copper or aluminum, and the proportion of aluminum motors. This information is vital for determining the quality of the goods.
Additionally, some motors may contain a small amount of permanent magnets, which are made of rare earth materials such as neodymium, iron, and boron. These magnets are highly valuable and can be separated and sold separately to increase the value of the product.
