Injection molding for insulating linear motor lamination stacks involves a precise process to ensure the production of high-quality components. First, a suitable insulating material, such as thermoplastic or thermosetting polymers, is selected based on its electrical and mechanical properties.

The material is then heated to a molten state and injected into a mold cavity that is specially designed to form the desired shape of the lamination stack. The mold is typically made from hardened steel to withstand the high pressures and temperatures of the injection molding process.

Once injected, the material is allowed to cool and solidify, forming the insulating layer around the motor laminations. This process ensures uniform insulation and tight tolerances for optimal performance of the linear motor.


linear motor laminations Winding

The winding process for linear motor lamination stacks involves carefully wrapping insulated copper wire around the laminations to create the electromagnetic coils.

Each coil is wound in a specific pattern and number of turns to achieve the desired performance characteristics, such as torque and speed. The wire is typically wound around a bobbin or form to maintain the shape and spacing of the coils.

Additionally, the winding process may include techniques such as layering or interleaving to optimize the magnetic field distribution and reduce eddy currents. After winding, the coils are often impregnated with varnish or epoxy for insulation and mechanical stability.
