Are you ever curious how an electric motor works and what makes it run? It all starts with electric motor laminations.
Electric motor laminations make up the core of every electric motor and help power a wide range of things from everyday objects to complex assemblies used in Aerospace and defense applications. Let’s dive into what these components are, the process of electric motor lamination manufacturing, and why they’re important for actuators, pumps and several other machines that rely on electricity.
WHAT ARE ELECTRIC MOTOR LAMINATIONS AND THEIR IMPORTANCE?
Electric motor laminations are a crucial component of an electric motor. They allow the motor to be more efficient and reliable by reducing losses in energy due to eddy currents, hysteresis, and core loss.
As the name implies, electric motor laminations are made of thin steel that is cut to specification then bonded or welded together to form an electrical machine’s stator or rotor core. The steel laminations reduce the total amount of material used in the construction of the motor while creating a low-resistance path for current flow that reduces eddy current losses in the motor’s windings.
UNDERSTANDING THE PROCESS OF ELECTRIC MOTOR LAMINATION MANUFACTURING
Here’s the guide on the process of electric motor lamination manufacturing and fabrication:
- It begins with selecting an appropriate core material. LCS has vast experience with several different materials and thicknesses. Some of the most commonly utilized materials being Silicon Electrical Steel (NGOES), Cold Rolled Motor Lamination (CRML), and Cobalt or Nickel alloys.
- Once the core material has been selected, the next step is to either laser cut or stamp parts per the your designed drawing/specifications. Laser cutting is a good fit for smaller volume and prototype stages. Stamping is often a better fit for production volumes as it requires tooling to be built.
- After laminations have been laser cut or stamped they may require post annealing to relax stresses or meet magnetic requirements.
- Lastly LCS does final inspection and securely packages parts for delivery. These laminations can then be aligned using fixturing and bonded or welded together. LCS can also provide in die interlocking capabilities, which stakes laminations into a stack right in the tool.
BENEFITS OF ELECTRIC MOTOR LAMINATIONS
Motor laminations are essential components of electric motors and generators, as they are responsible for reducing eddy currents, heat and providing better overall performance . This makes them invaluable to any electric motor or generator construction project.
- Reduced Energy Loss: One of the primary benefits is their ability to reduce energy losses due to eddy currents. By creating multiple layers separated by thin metal sheets, the eddy current created by alternating magnetic fields can be greatly reduced, allowing for more efficient motor operation.
- Compact Design: Another benefit of electric motor lamination manufacturing is the lightweight and small size achieved compared to other materials. This makes them suitable for various applications, from small, hand-held electric motors to large industrial machinery.
- Thermal Management: Electric motor laminations are also beneficial for temperature changes. When electricity passes through metal sheets, heat is generated. These laminations help reduce this risk by providing insulation for consistent temperature throughout the entire motor.
