Capabilities For Segment Motor Lamination Design And Manufacture

We have a high-precision segmented motor core(a segmented motor lamination or segmented stator/rotor) process, a specialized design approach used in electric motor core construction.

Segment Motor Core

The segmented motor core is composed of several iron cores. Each iron core’s inner measuring arc edge is concave to form a plurality of tooth slots. Then, the multiple rings punched are superimposed winding together, and the joints on the adjacent rings are staggered. Achieve a complete motor core.

We segmented motor stator cores are commonly configured with 12 slots and ten poles or 12 slots and 14 poles suitable for motors in automotive applications to save material use.

In addition, we consider separate production of rotor and stator laminations, the width of the air gap is no longer determined by the limitations of the stamping tool.

Therefore, our segmentation operation minimizes the clearance and increases the air gap flux and torque.

Benefits Of Segmented Motor Stator&Rotor

Our motor lamination is constantly innovative in manufacturing and bringing forth the exceptional benefits of segment motor lamination.

Reduced Eddy Current Losses

Segmented Motor Laminations FAQs

The stator core is a stationary part of an electric machine, such as a motor or a generator. It consists of a stack of laminated steel sheets or plates that are tightly bound together.

The rotor core is the rotating part of an electric machine, such as a motor or a generator. Like the stator core, it is also made up of stacked laminated steel sheets or plates insulated from each other.

China is known for its advanced manufacturing capabilities and cost-effective solutions. Choosing a segment motor lamination manufacturer in China allows you to access cutting-edge technology, high-quality materials, and competitive pricing.

Stamping and Die-Cutting: Stamping and die-cutting are primary processes to create individual laminations from thin electrical steel sheets. Stamping involves using precision dies to cut and shape the laminations from the steel sheets.

Lamination Insulation: The laminated surfaces apply coatings, varnishes, or insulating films to prevent electrical conductivity between them.

Stacking: The stacking(such as riveting, cleating, laser welding, TIG+MIG welding, gluing, and self-bonding) method of tight laminations stacks the sheets together to form the motor core.

Annealing: Annealing is a heat treatment process that helps optimize the magnetic properties of the laminations.

Precision Machining: To achieve specific dimensional tolerances or surface finishes using machining or grinding processes.

Absolutely. Our design team’s expertise allows us to create customized laminations for various motor types, ensuring optimal performance and efficiency.
