02 / LMS Solution
A moving-magnet logistics system that
drives carriers independently, with no cables.
Carrier transport is performed through the continuous operation of individual coils, while carrier position control is based on hall sensors at the entry point. Rather than a coil (motor), a magnet array is attached to and moves with the carrier — a structure that requires no separate external position-detection sensors.
LMS (Linear Motion System) Advantages
- Carrier transport without cables, even inside a vacuum
- Independent high-speed, high-precision position control of multiple carriers in high-temperature and special environments
- Non-contact carrier position sensing using hall sensors — no separate encoder required
- Supports not only straight tracks but also circular and oval tracks, elevators, and shift transfers
- Maximizes productivity with no carrier waiting time, and enables logistics automation layout innovation through tracks of virtually any shape
02-1 / LMS Solution Configuration
LMS SOLUTION CONFIGURATION
- 01Composed of the CPACK and LCS series, and compatible with an upper-level PLC (Mitsubishi), so your existing user HMI can be used as-is.
- 02A single CPACK control unit supports up to 255 connected drives, and adopts package drives that connect up to 4 drives as a single package.
- 03Up to 3 CPACK control units can be connected to a single PLC.
02-2 / LMS Performance
PERFORMANCE
- Wide payload and transport range: A broad spectrum covering everything from small parts to large loads of up to 1.5 tons.
- High-speed transport: Moves large, heavy loads at speeds of up to 5 m/s, delivering excellent cost-effective productivity.
- Reliability in extreme environments: In addition to standard NdFeB magnets (70°C), a high-temperature magnet option (SmCo magnet) supports operation up to 150°C.
- Wide air gap: A generous 1–5mm air gap flexibly absorbs assembly tolerances and maintains stable running even with minor rail contamination or deformation.
02-3 / Two LMS Guide Types
| Roller Guide | LM Guide | |
|---|---|---|
| Repeat Position Accuracy | ±0.05 ~ ±0.1 mm | ±0.005 ~ ±0.01 mm |
| Position Accuracy | ±0.1 ~ ±0.5 mm | ±0.01 ~ ±0.05 mm |
| Mechanical Characteristics | For smooth travel, elastic deformation of urethane or special-resin rollers and step differences between rails can cause some play | Very high rigidity from ball/roller rolling contact, with extremely little mechanical play |
| Application | Excellent cost-effectiveness for pure high-speed logistics sections; advantageous for high-speed travel; carrier-fixing mechanisms used in work sections | Installation cost increases with distance; excellent positioning accuracy; suitable for work performed while the carrier is stationary |
| Air Gap | Selected within 1~5mm; maintaining the air gap is critical to precision | Fixed within 1mm |
