Scrap electric motors are a treasure trove of recyclable materials, primarily copper and aluminum, which are in high demand. The robust construction of these motors often includes steel casings that safeguard the valuable metals within. To access these materials, specialized recycling machines are employed, capable of disassembling motors and separating the components efficiently. The process involves a three-stage system: initially, the outer casing is removed to reveal the motor's internal structure. Following this, the stator or transformer block is cleaved to expose the copper coils. Finally, a hydraulic system extracts the copper wiring, leaving behind other recyclable materials such as scrap metal and plastic. This efficient separation process ensures that the valuable copper and aluminum components are cleanly isolated, ready for reuse or resale, contributing to a sustainable recycling practice.

Electric motors are comprised of various materials and components that are essential for their operation. The core of the motor, which is integral to the creation of the magnetic circuit, is typically made of silicon steel, a material chosen for its magnetic properties. This core is divided into two parts: the stator core and the rotor core, separated by an air gap. The stator core in DC motors, excited by direct current, does not require lamination and is made of soft steel. Conversely, the rotor core, which is subject to flux changes with rotation, utilizes a laminated core to accommodate these variations.

In the construction of these motors, wires and conductors are predominantly made of copper, with aluminum being used occasionally. These wires are responsible for carrying the electric current. In the context of motor windings, these conductors are often referred to as magnet wires or enameled wires, the latter term being used due to the enamel resin that serves as an insulating material.

Insulation is a critical aspect of electric motors, preventing current from flowing to unintended locations. Various materials serve as insulators, including rubber, enamel, high-molecular compounds, resins, paper, mica, and glass fiber. These materials ensure that the electric motors operate safely and efficiently. Additionally, the use of a yoke, which is a core that combines two magnets with flux, is another component that plays a pivotal role in the functionality of electric motors.
