- High Force Density: Patented winding technology achieves the highest coil density in the industry, producing 20-60% more force per millimeter of coil length compared to conventional designs.
- Low Moving Mass: The ironless design removes weight from the moving coil enabling higher accelerations.
- Reduced Thermal Losses: Efficient thermal management minimizes heat generation, ensuring consistent performance even under demanding conditions.
- Customizable Configurations: Available in various sizes and force ratings, Allient’s ironless linear motors can be tailored to meet specific application requirements.
- Patented Copper Coil Manufacturing and Winding Methods: Ensures precision placement of conductors with minimal end turns, high slot fill, and an optimal thermal path.
- High Motor Constant (Km): Provides industry leading efficiency in force output per square root watt of dissipated power as heat.
- Rare Earth Magnets: Completes the magnetic circuit with high energy, Neodymium based, temperature tolerant, magnets.
- Bracketless Coil Assemblies: Ideal for integration into custom stages.
- Multi-Unit Module Coils and Magnet Tracks: Easily customizable designs for longer travel and complex motion systems.
- Extremely Low Inductance: With no iron surrounding the coil, inductance is significantly reduced, allowing the motor to respond much faster to current changes and enabling high-fidelity, high-bandwidth control.
- Zero Magnetic Attraction to the Magnet Track: Because the coil contains no iron, there is no varying attractive force, meaning preload does not fluctuate and cogging is essentially eliminated.
- Rapid Current Response: Low electrical time constant for high accuracy, repeatability, and fast settling times.
- Extensive Customization Options: Including added mounting holes, special brackets, custom cables, integrated thermal sensors, vacuum-compatible hardware, cleanroom-ready construction, special plating, private labeling, multi-unit coil modules, and custom magnet tracks.

Benefits of Allient’s Ironless Linear Motors
- High Efficiency: The absence of iron in the moving parts eliminates hysteresis and eddy current losses, resulting in superior efficiency.
- Smooth Operation: The ironless design ensures low force ripple, providing consistent and smooth motion essential for delicate processes.
- Energy Efficiency: Optimized designs reduce power consumption, contributing to lower operational costs and environmental impact.
- Ultra-Responsive Control: High motor constant (Km) combined with low electrical time constant ensures precise control, high repeatability, and fast point-to-point settling times.
- Eliminates Backlash and Wear: High intrinsic coil stiffness and direct drive design remove issues associated with ball screws, belts, and rack-and-pinion systems.
- Closed-Loop Control: In closed-loop systems, the motor acts like a linear electromagnetic spring, where current direction and magnetic flux determine motion, enabling very stable velocity and precise positioning.
