We offer electric motor rotor and stator lamination stamping techniques, including compound stamping, progressive stamping, and rotary notching.
Compound Stamping
The compound stamping technique involves using a compound stamping die, which combines multiple operations into a single stroke.
It begins with a coil of electrical steel fed into a compound die, simultaneously performing stamping operations such as blanking, piercing, and forming rotor lamination and stator lamination cores.
Over half of our compound stamping presses have been matched with automated systems. It enables high-speed production, improved dimensional accuracy, and enhanced repeatability.
Compound stamping is suitable for the medium size motor rotor and stator laminations. It is often used in Industrial Electric Motors, Electric Vehicles (EVs), Hybrid Electric Vehicles (HEVs), Renewable Energy Systems, Elevator Traction motors, etc.
Rotary Notching
Rotary notching is one of our core competencies; It is a cost-effective solution for large diameter electric motor laminations and low-to-medium volume production or large amounts of samples.
This process involves using a rotary notching tool that rotates at high speeds and removes electrical steel to create grooves or slots in the laminations. Our single-solt notching machines employ servo control systems, the notching speeds uo to 1,200 storkes/mins.
The outer diameter of our most extensive punching sheet is as high as 1250mm, currently the giant silicon steel coil’s width.
Progressive Stamping
Progressive stamping technology is our core competitive project, we have multiple 300T high-precision and high-speed progressive stamping lines. And enables the production of motor stator and rotor laminations with tight tolerances and high precision.
This process involves a series of sequential steps, where the silicon steel sheet is progressively fed through the die, carrying out high-speed stamping. It includes cutting, bending, forming, or piercing operations. Small-size but large-volume motor laminations are very suitable to be produced in a progressive die stamping way.
Motorneo progressive stamping motor cores are commonly used in automobiles, home appliances, drones, HVAC systems, power tools, etc.
Rotor&Stator Laminations Stacks Process
Motorneo offers an automation stack and assembles lamination services. Our lamination stacking process includes various methods, including riveting, cleating, laser welding, TIG and MIG welding, glue bonding, and self-bonding.
Design and Manufacture Compound Die
Employs CAD, Wire Electrical Discharge Machining (Wire-EDM), and high-precision grinders to design and craft stamping dies, such as progressive die, compound die, and notching die.
Wire-EDM enables us to create intricate shapes and contours in the die components, ensuring the highest precision and repeatability. Then, our skilled craftsmen utilize grinders to fine-tune the die surfaces, resulting in flawless finishes and optimal tooling performance.
Motorneo mold service department documents all settings and the number of mold strokes daily. To determine the current condition of the mold and estimated remaining life. Customer-owned molds are free of charge for service and repair of molds during their everyday mold life.
Aluminum Die-Casting Rotor Lamination
Aluminum die-casting involves injecting molten aluminum alloy into a precisely designed casting die under high pressure. It allows for the formation of complex rotor shapes with excellent dimensional accuracy.
We can manufacture cast various sizes of aluminum rotors and a largest outer diameter of up to 1250mm and also can deliver aluminum cage rotors that meet the highest industry standards.
For the aluminum die-casting motor rotor quality, we offer to visually inspect porosity, cracks, or unevenness surface defects, such as porosity, cracks, or unevenness.
Motorneo employ non-destructive testing techniques such as x-ray inspection or ultrasonic testing to identify any internal defects or irregularities that may affect the performance of the motor rotor iron core. These tests ensure the integrity and reliability of the die cast rotors.
Stator Assembly Winding In Motor Manufacturing
The stator winding process involves carefully winding the conductive wire onto the stator’s core. We offer two distinct methods for stator winding: automation winding and manual winding.
By automating the winding process, we can significantly increase production throughput, and reduce labor costs. Manual winding involves skilled technicians winding copper coils by hand around the stator core.
For the electric vehicle motor stator, we also offer new automation winding technology such as hair-pin winding, x-pin winding, and i-pin winding.
The winding line way can be customized based on the motor’s requirements, such as the number of poles, winding type (single-phase or three-phase), and desired torque-speed characteristics. The production capacity of the product specification needs to be more consistent. Basic 3-80 sets/day.
Applications Of Electric Motor Core
Motor rotor and stator core lamination find extensive applications across various industries and fields. They are commonly used in automotive applications, powering components such as electric power steering systems, pumps, and hybrid or electric vehicles. Motor stacks are employed in machinery and equipment, including wind/fire power generators, pumps, compressors, conveyor systems, and robotics in the industrial sector.
