Customized Stator And Rotor Lamination For Permanent Magnet Motor

We offer customized rotor and stator laminations for permanent magnet motors to meet the demands of various applications. These laminations are typically made from materials like silicon steel to maximize the motor’s magnetic flux density and minimize energy losses due to eddy currents and hysteresis.

Due to their high efficiency, low noise, small size, and high reliability, our permanent motor lamination stacks have broad application prospects in many fields. Such as industry drive machine tools, automated production lines, new energy vehicles, home appliances such as air conditioners, washing machines, refrigerators, and vacuum cleaners, as well as office automation equipment such as printers, scanners, copiers, medical equipment, ship lifting equipment, aircraft landing gear, etc.

For those seeking prototype development or low-volume production runs, we offer laser cutting and wire-EDM (Electrical Discharge Machining). These cutting-edge technologies enable us to swiftly and accurately design and create custom lamination prototypes. The prototyping lamination employs glue bonding, self-bonding, laser welding, tig+mig welding, and cleating to stack and bond complete iron cores.

Permanent Magnet Motor Lamination Prototyping

We offer laser cutting and wire-cutting technology to produce permanent magnet motor lamination prototyping.

Laser-cutting motor laminations involve using a high-powered laser beam to precisely cut and shape thin sheets of metal, typically thin lamination steel, to create the laminations needed for permanent magnet electric motors.

Wire cutting, also known as wire EDM (Electrical Discharge Machining), is utilized to create precise cuts in electrical steel materials using a thin, electrically charged wires.

With two cutting methods, permanent magnet motor lamination prototypes can be rapidly developed within a lead time of 5-15 days.

Tooling Design And Manufacture For Permanent Magnet Motor

Our designers utilize CAD software and extensive knowledge of material properties to craft dies tailored to specific production needs. Precision machining techniques such as CNC milling and EDM are then employed to fabricate the die components with utmost accuracy.

The effective die contributes to the cost-effective mass production of high-quality motor stator and rotor laminations. We offer soft tooling, progressive die, compound die, and single-slot notching die chosen for customers.

Lamination Stamping For Permanent Magnet Motor

Permanent magnet motor lamination stamping encompasses various techniques, including progressive stamping, compound stamping, and rotary notching, to produce precise and efficient motor components.

lamination stacks of industry motor cores

Progressive stamping involves feeding a continuous electrical steel strip of metal through a series of stations, where different operations such as cutting, bending, and forming are performed progressively. This method enables high-speed production with minimal material waste.

Compound stamping combines multiple operations into a single die, enhancing efficiency and accuracy. It’s particularly useful for medium and large permanent magnet laminations.

Rotary notching employs servo systems to control rotating tools to notch the laminations, allowing for precise cuts and reduced tool wear. It is cost-effectiveness for large laminations and prototypes.

Lamination Bonding And Stacking For Permanent Magnet Motor

Lamination bonding and stacking refer to the process of assembling individual laminations to form the core of an electric motor or transformer.

The bonding process involves joining the laminations together using various methods such as glue bonding, self-bonding, welding, riveting, cleating, or interlocking.

Our automation stacking process ensures consistent alignment and orientation of the laminations, minimizing errors and optimizing the performance of the final product.

Automation stacking machines can handle large volumes of laminations efficiently, increasing production throughput and reducing labor costs.

Permanent Magnet Motor Stator Winding

The stator winding in a permanent magnet motor is a crucial component responsible for generating the electromagnetic field necessary for motor operation.

Our stator winding configuration depends on the motor’s design and intended application to offer concentrated windings, distributed windings, and fractional-slot windings.

The automation winding process involves carefully inserting and securing the copper wire coils into the stator slots, ensuring proper insulation and alignment.

We employ advanced winding techniques, such as hairpin winding or wave winding to enhance motor performance and efficiency.
