What materials are best for servo motor stators and rotors?

High-grade laminated electrical steel with low magnetic losses is ideal for servo motor stators. Rotors are often made of aluminium die-cast or high-quality magnetic materials to ensure efficiency, heat resistance, and minimal torque ripple.

What industries use servo motor cores?

Servo motor cores are widely used in robotics, CNC machines, industrial automation, precision pumps, medical equipment, and energy applications where high accuracy and reliability are critical.

What sizes of servo motor stators can Yuanzhong manufacture?

We manufacture servo motor stators with diameters ranging from 20mm to 600mm, with tolerances as tight as 0.02mm, ensuring precision for a wide range of industrial applications.

Can servo motor cores be customised for specific applications?

Absolutely. We provide custom stator lamination designs, tailored rotor configurations, and application-specific material selection to optimise torque, speed, and energy efficiency.

How does a servo motor core improve energy efficiency?

Precision-stamped laminations and optimised stator-rotor design minimise energy losses and heat generation, improving motor efficiency and reducing operational costs over time.

What Are Servo Motor Stators and Motor Cores?

Servo motor stators are stationary electromagnetic components that generate the magnetic field required for precise motion control. Manufactured from laminated electrical steel, they enable efficient torque and speed regulation. A servo motor core combines the stator and rotor to minimise energy loss, optimise magnetic flux, and ensure fast response, stability, and long service life in precision applications. Key roles include:

Generating a uniform electromagnetic field for consistent torque output

Supporting precise positioning and speed regulation

Reducing core losses to improve energy efficiency

Enhancing thermal stability during continuous or high-speed operation

How Rotor in Servo Motors Work?

In a servo motor, electrical current flows through the stator windings, creating a controlled magnetic field. This field interacts with the rotor in servo motor assemblies, causing the rotor to rotate in precise increments based on feedback from the control system. The interaction works as follows:

Stator Magnetic Field

The stator creates a controlled magnetic field that drives rotor movement based on electrical input signals.

Rotor Alignment

The rotor aligns with the stator’s magnetic field, rotating precisely according to control system feedback and commands.

Continuous Feedback

Sensors adjust current flow in real time, ensuring accurate rotor positioning and smooth servo motor operation.

Laminated Core Efficiency

High-quality laminated cores reduce energy losses and heat, enhancing efficiency, performance, and long-term motor reliability.

Precision Matters

Material choice, lamination quality, and dimensional accuracy directly impact smooth motion and motor lifespan.

Manufacturing Process of Custom Servo Motors

Yuanzhong follows a controlled, high-precision manufacturing process to produce servo motor stators that meet global performance standards.

Material Selection

High-grade electrical steel is carefully selected to ensure low magnetic losses, high permeability, and long-term durability.

Lamination Stamping

Laminations are stamped using either simple die or progressive die processes, depending on volume and design complexity. Tight tolerances are maintained to ensure clean edges and consistent geometry.

Stacking & Alignment

Individual laminations are stacked with precise alignment to form the stator core, ensuring uniform magnetic paths and mechanical stability.

Quality Inspection

Each stator undergoes dimensional checks, burr height control, and flatness inspection to guarantee consistency and performance.

Industrial Applications of Servo Motor in China

Yuanzhong’s custom stator lamination are widely used across high-precision industries:

Robotics : Servo motors power robotic arms, joints, and grippers where accuracy and repeatability are critical. Precision stator and rotor laminations ensure smooth motion and fast response times.

Automation Systems : In industrial automation, servo motors enable accurate positioning and speed control. High-quality laminations minimise downtime and energy losses in continuous operations.

CNC Machines : CNC machining relies on precise servo control for cutting accuracy. Optimised servo motor stators improve torque consistency and thermal performance during extended machining cycles.

Pumps & Fluid Control : Servo-driven pumps benefit from efficient motor cores that support variable speed control and energy optimisation.
