Servo Motor Lamination Core Design and Manufacture Capabilities

Tooling Design and Manufacture

The stamping die design and manufacture process starts with detailed specifications and design calculations to determine the optimal tooling size, shape, and configuration.

Tooling components are manufactured with high precision, typically through CNC machining or wire EDM techniques. This ensures the utmost accuracy and consistency.

Once the tooling is ready, it is assembled and tested. This involves verifying that the tooling is correctly aligned and that it can produce cores that meet the required specifications.

Stamping Lamination Stacks For Servo Motor

Motorneo offers progressive stamping and compound stamping processes for product servo motor stator and rotor lamination stacks.

The progressive stamping is cost-effective for small lamination cores’ mass production. Compound stamping is suitable for medium and large lamination mass production.

We have 25ton-300ton punching machines that can meet client specifical needs. Our lamination stacks for servo motors are employed in large-scale automation systems.

Servo Motor Lamination Prototyping

The Servo motor lamination prototyping process typically involves laser cutting and wire cutting to create prototype laminations.

Laser cutting uses a high-powered laser to accurately cut through materials like steel, resulting in clean and precise cuts.

Wire cutting uses a thin wire, usually made of tungsten, to cut through the workpiece with high precision.

Our lead time for lamination prototyping usually falls between 5 and 15 days, depending on factors such as the complexity of the design and the availability of materials.

Secondary Processing Technology Of Servo Electric Motor Lamination Stack

servo motor lamination bonding and stacking

Lamination Bonding and Stacking For Servo Motor

The interlocking process within high-speed stamping involves aligning the laminations so that they fit together precisely. In addition, for the segmented servo motor stator, we employ the dovetail slot method interlocking slots.

Gluing is a common method that uses adhesives to bond the laminations. These adhesives are often specially formulated to ensure strong and durable bonds that can withstand the stresses and heat generated by the motor.

Self-bonding laminations have a special coating that activates when exposed to heat during the operation, creating a bond between the laminations without the need for additional adhesives.

Injection Molding Of Servo Motor Laminated Iron Core

Plastic overmolding enables the rapid production of large quantities of stator parts at relatively low cost.

Injection molding is a process used to create complex shapes by injecting molten material into a mold, where it solidifies into the desired form.

For servo motor stator cores, this involves injecting a thermoplastic material into a mold cavity. The mold is then cooled and the part is ejected, leaving behind a solid core with the required features.

Servo Motor Stator Winding

The stator winding process involves creating precise, evenly spaced copper coils of wire around the stator, which is the stationary part of the motor.

Our skilled technicians to the stator are mounted onto a winding machine. The winding process itself is automated, with the machine carefully controlling the speed and tension of the wire to ensure the coils are wound evenly and with the correct number of turns.

After winding, the coils are often impregnated with a resin or epoxy to protect them from moisture, dust, and other environmental factors.

Servo Motor Core FAQs

A servo motor is an electromechanical device that provides precise control of angular or linear position, velocity, and acceleration. Servo motors are used in automation, robotics, CNC machinery, and other applications requiring accurate motion control.

The basic working principle of a servo motor is to maintain a desired position, speed, or torque by continuously comparing the actual output with the desired output and adjusting accordingly. This real-time feedback signal is what sets servo motors apart.

High Precision:

Servo motors provide high accuracy and accurate controllers over position, velocity, and torque. 

Fast Response Time:

Servo motors have rapid response times, making them suitable for applications that require quick and precise adjustments, such as tracking moving objects or maintaining tight tolerances during manufacturing.

High Torque-to-Inertia Ratio:

Servo motors typically offer high torque relative to their size and weight, allowing for compact and efficient designs. This is particularly advantageous in applications with space constraints.

Variable Speed and Torque:

Servo motors can operate over a wide range of speeds and torque levels, offering flexibility in various applications. They can deliver torque at low speeds and maintain constant speed under varying loads.

Closed-Loop Control:

Servo systems use feedback devices like encoders or resolvers to continuously monitor and adjust the motor’s position. This closed-loop control ensures precise and consistent performance, even in the presence of external disturbances.

Energy Efficiency:

They are high efficiency, with low electrical losses and a high power density, allowing smaller motors to generate more torque.

Smooth Operation:

They provide smooth and consistent motion, reducing vibrations and minimizing wear and tear on mechanical components. This feature is valuable in applications that require gentle handling or fine surface finishes.

Wide Range of Applications:

Servo drive motors find applications in a wide range of industries, including manufacturing, aerospace, automotive, robotics, medical devices, and more. Their versatility and adaptability make them suitable for diverse tasks.

Compatibility with Automation:

Servo motors are often integrated into automated systems, enhancing the efficiency and productivity of industrial processes. They can communicate with PLCs and other control systems for seamless automation.

Each of these motors operates differently and has unique performance requirements.

Since AC servo motor core comprises several parts, including a stator, rotor, and electrical components such as windings(stator coil) and magnets.

DC servo motors are reliable and efficient at producing high-torque output under varying speed loads. It is a brushed permanent magnet motor commonly used in smaller projects. DC motor requires its low cost, efficiency, and simplicity.

Servo motors can provide smooth motion compared to stepper motors. Switching high speed and high torque is done seamlessly for human-like sensitive motions.

With an AC servo motor, the encoder detects the rotation angle and speed and controls the motor rotation with electric current, which allows for smooth motions. In contrast, stepper motors control the rotation angle and speed with the pulse frequency.

The rotation angle per pulse is fixed, and a motor rotates through that angle every time it receives a pulse signal.

Riveting involves fastening the laminations together using rivets or pins. This method provides a mechanical connection.

Cleating involves the insertion of cleats or tabs between individual motor stator lamination to provide additional stability and alignment within the motor core.

Welding involves laser and TIG+MIG welding, fusing the laminations using heat or pressure.

Gluing lamination is the application of adhesive or glue to bond individual laminations together to form the core of an electric motor.

Self-bonding property is through pressure and heat applied during the motor lamination stack assembly.
