Compound Stamping Capabilities For Motor Lamination Stacks

Our compound precision stamping process produces a complete motor lamination in one action. The laminated core with superior concentricity and flatness and is a good choice for medium and large production.

The process begins with the selection of high-quality electrical steel sheets. Silicon steel is commonly chosen due to its excellent magnetic properties and ability to minimize energy losses.

In the lamination stamping phase, the selected thin-gauge electrical steel is automotive fed through a stamping press. This press is equipped with intricate dies that cut and shape the sheets into the desired lamination design. The precision of this step is crucial for maintaining the required tolerances.

The stamped laminations are then employed in bonded and stacked to form the core. The stacking arrangement is designed to optimize magnetic flux and minimize core losses.

Advantages of Compound Stamping Motor Core Laminations

The compound stamping process for motor laminations offers several advantages, contributing to the overall efficiency and performance of electric motors. Here are the key benefits associated with the use of compound stamping:

Tight Tolerances

The use of advanced stamping presses enables us to produce precision stator and rotor components with tight tolerances, high accuracy, repeatability, and reliability.

Cost Effective

Compound stamping allows for the integration of multiple operations into a single die, which can result in lower tooling costs compared to having separate dies for each operation.

Faster Production

The ability to perform multiple operations in a single stroke speeds up the production process, leading to increased throughput and reduced manufacturing costs.

Material Savings

The precision and efficiency of compound stamping help reduce material waste by minimizing errors and optimizing the use of raw materials.

Mass Production

Compound stamping is suitable for large motor lamination production, meeting the demands of large-scale manufacturing.

Consistent Quality

The controlled and automated nature of the compound stamping process ensures consistent quality in the production of motor laminations.

Compound Punching FAQS

Compound stamping is particularly advantageous for motors with complex geometries, such as those used in high-efficiency electric vehicles, industrial machinery, and other applications requiring precise and intricate lamination industry.

Compound stamping plays a crucial role in achieving high motor performance by ensuring precise lamination shapes, minimizing energy losses, and optimizing the magnetic properties of the motor core. This contributes to improved efficiency and reliability of the motor.

While compound stamping is highly efficient for high-volume production, it may not be as cost-effective for low-volume runs. In such cases, alternative stamping methods or manufacturing processes might be more suitable.

Compound stamping and progressive die stamping involve a sequence of dies, but the key difference lies in the complexity of the operations. Compound stamping uses multiple dies simultaneously to shape intricate features, while progressive stamping relies on a sequential process with a single operation at each die for simpler parts.
