The stepper motor core is a key component of permanent magnet or hybrid stepper motors, typically made from high-precision silicon steel laminations. Designed for high precision and reliability, it enables precise speed and position control, widely used in industrial automation and 3D printing. A key feature is the ability to provide high-resolution stepping angles, such as the common 200 steps per revolution, or even higher precision 0.9° steps.
YUMA precision offer a full series of stepper motor cores ranging from 20mm to 86mm in size, with rotary stamping angles of 30°, 45°, 60°, 72°, 90°, 120°, and 180°.
Stepper Motor Manufacturer's Laminated Core Assembly
As China's premier precision motor core manufacturer, we understand that the most critical component of a stepper motor is its laminated core. We leverage our expertise and continuously pursue innovation to ensure every stepper motor rotor and stator laminate we produce delivers optimal quality, precision, and exceptional performance.
What is a Stepper Motor Laminated Core Assembly?
Stepper motors find widespread application across diverse fields requiring precise motion, from factory machinery and robotics to medical tools and 3D printers. The meticulously designed and manufactured laminations within these motors form the stator and rotor. These thin sheets of specially coated steel not only anchor the motor but also guide magnetic energy, thereby controlling the motor's power, electrical efficiency, and motion characteristics.
The laminations serve two primary functions: First, they facilitate the flow of magnetic energy through the windings, ensuring efficient energy utilization. Second, they minimize energy loss caused by unwanted eddy currents (known as eddy currents). Without laminations, the motor's fluctuating magnetic field would generate massive eddy currents within a solid metal core. This would produce significant heat, waste energy, and impair motor performance. Cutting the core into thin laminations prevents these eddy currents from flowing, significantly reducing this energy loss.
