Capabilities Of Motor Core Lamination Cleating

Lamination is a process used to create the core of an electric motor. In this process, thin layers of a metal are stacked and bonded together. These cores are assembled by forcing steel straps into notches in the periphery of the laminations. This method provides for good dimensional stability with very little increase in core loss.

motor lamination cleating process

The first step is to design the shape of the core, including the size, the number of laminations, and the arrangement of cleats. This is usually done using computer-aided design (CAD) software.

The laminations are typically made from thin sheets of silicon steel or other magnetic materials. The thickness of each lamination is chosen based on the desired performance of the motor.

The laminations are then stacked together to form the core. Each lamination is carefully placed on top of the previous one, ensuring that the magnetic properties of the core are maintained.

Once the laminations are stacked, the cores are assembled using a cleating machine. The cleating machine punches holes or slots within the stator laminations at specific locations. These holes or slots are used to insert small pieces of galvanized strips/CR strips in thickness of up to 2mm as per desired core length, which helps hold the laminations together.

Benefits Of Electric Motor Lamination Stacks Cleating

Cleats are typically folded over the ends of the motor cores and may have an adverse effect on electrical clearance. However, this method provides for good dimensional stability with very little increase in core loss. Here are some benefits:

Improved Core Strength

Cleating helps to hold the laminations together more securely, increasing the overall strength and stability of the core. This reduces the risk of the laminations separating during use.

Reduced Vibration and Noise

The secure bonding of the laminations reduces the vibration and noise produced by the motor during operation. This results in a quieter and smoother-running motor.

Enhanced Cooling

The cleating process creates small gaps between the laminations, allowing for better airflow through the core. This improves the cooling efficiency of the motor, which can help to extend its lifespan and prevent overheating.

Improved Performance

The increased strength and stability of the core, along with the reduced vibration and noise, can lead to improved motor performance. This includes higher efficiency, better torque output, and smoother operation.

Cost Savings

Cleating helps to reduce the risk of motor failure, which can lead to significant cost savings in terms of repairs and replacements. Additionally, the improved performance and efficiency of the motor can result in lower energy consumption.

Laminations Cleating FAQS

The primary purpose of cleating stator laminations is to hold the individual laminations together, ensuring that they maintain their position and alignment during the motor’s operation. This helps to prevent vibration, reduce noise, and enhance the overall stability of the motor core.

When designing cleats for stator laminations, factors such as the size and shape of the cleats, the spacing between cleats, and the material used for the cleats should be considered. These factors can affect the overall performance and efficiency of the motor.

Cleated stator laminations are manufactured using a specialized machine that can create precise holes or slots in the laminations. The cleating process involves stacking the laminations together, punching holes or slots in the edges, and then bonding the laminations together.

Yes, cleating can be customized to meet the specific requirements of different motor applications. This cleating involves designing the size, shape, and arrangement of the cleats to fit the needs of the motor.

In addition to the cleating process, we offer bonding adhesive, riveting, cleating, and welding technology to bonded core laminations. The glue-dot bonding and self-bonding are high-tech manufacturing technology is becoming more and more mature.
