High-Performance Motor Core – Efficient Magnetic Circuit, Reduced Power Consumption, CNC Precision

High-Performance Motor Core – Efficient Magnetic Circuit, Reduced Power Consumption, CNC Precision

Product Description:

The Motor Core is a key magnetic component used in electric motors and generators, consisting of stator and rotor laminations that convert electrical energy into mechanical motion efficiently. At METS, our motor cores are manufactured with high-grade silicon steel or cold-rolled electrical steel, providing low core loss, high magnetic permeability, and excellent thermal stability, which significantly enhance the performance and lifespan of the motor.

Each lamination is precisely produced using high-speed progressive stamping, laser cutting, or wire EDM technology to ensure accurate dimensions, minimal burrs, and consistent stacking alignment. The laminations are then interlocked, bonded, or welded to form a highly compact core that ensures stable magnetic flow, reduced eddy current loss, and low noise operation.

Our motor cores can be fully tailored to customer requirements, including:

• Outer diameter, inner hole size, and slot design

• Stack thickness and lamination shape

• Surface coating options (insulation coating, epoxy, electrophoresis, or anti-rust treatment)

• Rotor shaft integration or stator housing assembly

These motor cores are widely used in:

• Electric vehicles (EV motors, hybrid motors)

• Industrial machinery and servo motors

• Household appliances (washing machines, air conditioners, refrigerators)

• Power tools and garden equipment

• Wind turbines, generators, pumps, and compressors

We ensure each product meets international standards such as ISO, IEC, RoHS, and REACH. With advanced production equipment and strict quality inspection, METS delivers motor cores that offer:
 High magnetic efficiency and low energy consumption
 Stable operation with low vibration and noise
 Superior mechanical strength and long service life
 Support for OEM/ODM and mass production
