Capabilities For Wire Cutting Motor Stator And Rotor Lamination

The manufacturing process of wire-cutting motor lamination, also known as Wire EDM (Electrical Discharge Machining), is a micron-level precision method used to cut motor lamination. This process involves using a thin wire electrode that emits a controlled electrical discharge to erode the workpiece material, which is typically electrically conductive.

electrical steel laminations prototyping

The process begins with the design and programming of the desired motor lamination shape using Computer-Aided Design (CAD) software. This design is then converted into a program that guides the wire EDM machine during cutting.

The workpiece, which is often a block of metal or a stack of laminations, is secured in the wire EDM machine using clamps or a fixture. The machine’s table and spindle are then positioned to align with the desired cutting path.

A thin wire electrode(between 0.02 mm and 0.33 mm in diameter), typically made of brass or copper, is threaded through a small hole in the workpiece. The wire is continuously fed through the workpiece during the cutting process.

The wire EDM machine generates a spark between the wire and the workpiece. This controlled electrical discharge, or spark, erodes small particles of material from the workpiece, gradually forming the desired shape.

As the wire cuts through the workpiece, it is continuously fed into the machine to maintain the desired cutting depth. The wire EDM machine may also use a flushing system to remove debris and cool the workpiece during cutting. Once the desired shape is cut, the grinder process can be used to create fine surface finishes.

Benefits Of Wire-Cutted Core Laminations


Wire EDM is highly precise, capable of creating intricate shapes and features with tolerances as tight as ±0.0001 inches. This precision is especially crucial in motor lamination.

Minimal Material Wastage

The wire EDM process does not involve direct contact between the cutting tool and the workpiece. There is minimal material wastage.

No Heat-Affected Zone

Unlike other cutting methods like laser cutting or plasma cutting, Wire EDM does not create a heat-affected zone (HAZ) in the workpiece.

Complex Shapes

The wire EDM process can create complex geometries and features. This capability is particularly beneficial in motor lamination, where optimal performance.

Reduced Tool Wear

Since there is no physical contact between the wire electrode and the workpiece, there is minimal tool wear, resulting in longer tool life and reduced maintenance costs.

High Surface Finish

Wire EDM electric motor core lamination can achieve a high surface finish quality, eliminating the need for additional finishing processes and achieving quick turnaround times.
