A linear motor is essentially an electric motor that produces linear motion directly—no need for rotary-to-linear conversion like with ball screws or belts. Instead of spinning, it pushes or pulls a moving forcer (coil) along a stationary magnet track. 🏭 About Hiwin Hiwin Technologies Corp. is a Taiwan-based company well-known for: Linear guides Ballscrews Industrial robots Linear motors (iron core, ironless, and tubular) Hiwin offers several types of direct-drive linear motors, giving you smoother motion, faster speeds, higher accuracy, and zero backlash compared to mechanical systems. 🧲 Types of Hiwin Linear Motors 1. Iron Core Linear Motors (Model: LMC) Forcer: Copper coil + laminated iron core Stator: Permanent magnet track Features: High force output Good heat dissipation Excellent for heavy-duty applications Applications: Machine tools, heavy-load automation, printing 2. Ironless Linear Motors (Model: LMU) Forcer: Coil with no iron (less cogging) Stator: Dual magnet track (U-shaped) Features: No cogging (very smooth) Lightweight forcer Ideal for precision/high-speed moves Applications: Semiconductor, electronics, inspection 3. Tubular Linear Motors (Model: LMT) Structure: Cylindrical – coil inside a tube with magnets Features: Compact Easy to integrate Good for linear actuators Applications: Pick-and-place, packaging, actuators 📐 Key Specs (varies by model) Spec Range (Typical) Peak Force 30 N – 2500+ N Continuous Force 10 N – 1000+ N Speed Up to 5 m/s Repeatability Sub-micron possible Stroke Length Customizable (from cm to meters) Cooling Options Natural or water-cooled 🛠️ Components in a Hiwin Linear Motor Setup Forcer (moving part) – the coil assembly Magnet track (stator) – fixed magnets Linear encoder – for position feedback Servo driver/controller – to manage power & motion Cable carrier/drag chain – to manage wiring 💡 Advantages of Hiwin Linear Motors ✅ Direct drive = no backlash, no gear wear ✅ High acceleration/deceleration ✅ Smooth and precise (great for servo loops) ✅ Long life, less maintenance (no mechanical contact) ✅ Can operate in vacuum or cleanroom settings (ironless types) 📘 Example: Hiwin LMC Series (Iron Core) Peak Force: Up to 2000+ N Voltage: 230 V Cooling: Optional water-cooled versions Mounting: Easy integration with Hiwin linear guideways 📦 Common Applications CNC machines (spindles, axes) Semiconductor manufacturing Flat panel displays (LCD/LED lines) Laser cutting/etching Medical automation High-speed inspection systems Robotics 🧠 Integration Considerations Choose proper motor driver (servo amplifier) compatible with the coil specs Pair with a linear encoder (optical/magnetic) for closed-loop control Consider cooling requirements for high-duty cycles Align the forcer precisely over the magnet track to avoid magnetic losses 📎 Helpful Extras from Hiwin CAD models and datasheets available for each motor Motion simulation tools Application engineering support Pairing kits with Hiwin linear guideways and carriages
