Motorneo employs high-precision compound die stamping and high-efficiency, high-speed stamping processes to produce linear motor laminations. We maintain a variety of stamping dies(such as compound die, progressive die, and soft tooling) to cater to the distinct requirements of our clients.
Our high-speed stamping process allows for efficient mass production. This means we have shorter lead times, cost-effectiveness, and the ability to meet high-volume demands.
Linear Motor Lamination Prototyping
The linear motor lamination prototyping process involves using advanced techniques such as laser cutting and wire cutting to create precise, high-quality electrical steel laminations.
Laser cutting involves using a high-powered laser to cut through material with extreme precision, while wire cutting uses a thin, electrically charged wire to slice through the material.
Motorneo offers a lead time of 5-15 days for linear motor lamination prototypes, ensuring fast turnaround times without compromising on quality. This allows for rapid prototyping and testing, enabling faster development cycles for linear motor designs.
Secondary Processing Technology Of Linear Electric Motor Lamination Stack
Stacking and Bonding Linear Motor Lamination
The stacking and bonding of linear motor laminations process involves layering individual laminations on top of each other and bonding them together to form a core structure.
The interlocking process within high-speed stamping involves aligning the laminations so that they fit together precisely.
Self-bonding laminations utilize a material that adheres to itself when heated, forming a strong bond without the need for additional adhesive.
Gluing bonding involves applying a specialized adhesive between the laminations to create a secure bond. In addition, we offer a riveting process for stacking prototypes to the client’s requirements.
Injection Molding Of Linear Motor Laminates
Linear motor laminate plastic over mold is an insulation process that involves injecting molten material into a mold to create custom-shaped laminates for linear motors.
During injection molding, thermoplastic or thermosetting polymers are melted and injected into a mold cavity under high pressure. The material then cools and solidifies, taking the shape of the mold.
Motorneo has the capacity to plastic overmould with different material types: PA, PPS, PET fiberglass high loaded, to allow insulation of the iron laminated core slots with a minimum thickness of 0.5mm.
Linear Motor Stator Winding
The linear motor stator winding process involves winding copper wire coils around the stator’s core. Our winding patterns can vary based on the client motor’s application to offer combination or distributed windings.
Motorneo offers automated machinery winding and manual winding to prevent short circuits and ensure the motor’s longevity and safety.
Advantages Of Linear Electric Motor Lamination
High Precision: Linear motor cores can provide very high precision in terms of movement and positioning, making them ideal for applications that require high levels of accuracy.
Simple Structure: The tubular linear motor directly produces linear motion without going through an intermediate conversion mechanism, greatly simplifying the structure.
High Speed: Because there is no centrifugal force constraint, ordinary materials can also reach higher speeds. Making them suitable for applications that require rapid movement.
High Winding Utilization Rate: In the tubular linear induction motor, the primary winding is pie-shaped and there are no end windings, so the winding utilization rate is high.
Reduced Vibration: Linear motor lamination stacks can operate with reduced vibration compared to traditional motor designs, making them suitable for applications that require precise positioning.
Direct Drive: Linear motor stacks can operate as a direct drive system, eliminating the need for additional components such as gears or belts, which can reduce complexity and maintenance requirements.
Strong Adaptability: The main iron core of the linear motor can be sealed with epoxy resin, providing anti-corrosion, moisture-proof properties, and flexibility in design to suit various conditions.
High Reliability: Due to their simpler design and fewer moving parts, linear motor laminations can be more reliable than traditional motor designs, leading to less downtime and increased productivity.
Low Maintenance: Linear motor iron cores typically have fewer moving parts compared to traditional motor designs, which can lead to lower maintenance requirements and longer lifespans.
Energy Efficiency: Linear motor laminations can be more energy-efficient and operate more quietly than traditional motor designs, which can lead to cost savings over time.

Linear Motor Core FAQs
A linear motor is an electric motor that generates linear motion (motion in a straight line) instead of the rotational motion of a traditional rotary motor. It is commonly used in applications where precise linear movement is required.
Linear motors are known for their high precision and accuracy, making them ideal for tasks requiring precise positioning and control.
They have rapid response times and high acceleration capabilities, enhancing productivity in automation and manufacturing processes.
Additionally, linear motors generate reduced vibration and noise, contributing to quieter and more efficient operations. Their contactless operation eliminates friction, resulting in high efficiency and longevity.
In industrial automation, they power high-precision pick-and-place machines, conveyor systems, and semiconductor manufacturing equipment.
In the realm of transportation, linear motors are used in high-speed trains and maglev (magnetic levitation) systems for efficient, frictionless propulsion.
Robotics benefits from linear motors for precise and rapid movements in robotic arms and mechanisms.
3D and CNC machines employ linear motors for superior accuracy and dynamic performance.
Medical devices, such as MRI machines, utilize linear motors for precise patient positioning.
Stacking laminations in a linear motor involves precisely aligning and bonding the individual laminations to create the stator core. This process is crucial for achieving optimal performance. It typically includes methods such as riveting, cleating, laser welding, TIG+MIG welding, gluing, or self-bonding, depending on the design and requirements of the motor.
Iron core and ironless linear motors are two distinct types of linear motors, each with its own features. Here are the key differences between them:
Magnet Configuration
Iron core linear motors have a stationary iron core within the stator assembly. This core provides a path for the magnetic flux.
Ironless linear motors do not have a stationary iron core. They have a magnet track in the stator and a coil assembly in the mover.
Force Output
Iron core linear motors typically offer higher force output compared to ironless motors. They are capable of generating significant thrust and are suitable for applications that require strong linear forces. Iron core motors have a force density (force per working area) up to twice that of ironless motors. This means that in order to produce a given continuous force, an ironless motor would need to be twice as large as an iron core design.
Ironless linear motors generally offer lower force output compared to iron core motors. They are better suited for applications requiring smooth and precise motion rather than high force.
Cogging
Iron core motors may exhibit some cogging, which is a slight variation in attractive force due to the interaction between the iron core and the magnets. This low cogging can result in less smooth motion, especially at low speeds.
Ironless motors have minimal to no cogging, providing exceptionally smooth and precise linear motion. This makes them ideal for applications where smoothness and accuracy are critical.
Precision
Iron core linear motors are high-performance motion control devices designed for precise linear motion applications.
Ironless motors are commonly used in applications demanding high precision and accuracy, such as semiconductor manufacturing, medical devices, and optics.
Heat Generation
Due to the iron core, these motors may generate more heat during operation compared to ironless motors.
Ironless motors tend to generate less heat during operation because they lack the iron core.
Linear motor iron cores are typically made from high-quality magnetic materials known for their excellent magnetic properties. The most commonly used materials for linear motor iron cores include laminated silicon steel and iron-cobalt alloys.
