Large inventories of raw materials and semi-finished products enable delivery within 7 working days.

Linear Motor Selection and Calculation Guidelines

• Maximum thrust is calculated as: Thrust = Total Mass × Acceleration + Friction + External Forces.
• Acceleration is derived from motion distance and time using velocity profiles: triangular (no constant speed) or trapezoidal (with constant speed).
• Acceleration formulas:
  Triangular mode: Acceleration = 4 × Displacement / (Time²)
  Trapezoidal mode: Acceleration = Cruise Speed / (Total Time - Displacement / Cruise Speed)
• Continuous thrust (RMS force) accounts for acceleration, cruising, deceleration, and dwell phases weighted by their durations.
• A safety margin of 20-30% is recommended to cover friction and external forces.
• Example: For a 4kg load moving 0.3m in 0.2s with 0.15s dwell, maximum thrust is 120N and RMS thrust approximately 90.7N.

JGE Series Embedded Rail Linear Motor Modules

The JGE series provides cost-effective, compact, high-performance linear motor positioning systems featuring:

• Zero mechanical transmission and backlash-free operation.
• Speeds up to 3 m/s or higher and accelerations up to 2.5g or more.
• Encoder feedback via optical or magnetic scales with ±2μm repeatability.
• Effective travel ranges from 50mm to 1400mm.
• Multiple movers on a single rail with independent control.
• Low noise and maintenance-free operation due to direct drive.
• Fully enclosed steel belt structure suitable for dust-proof and cleanroom environments.
• Aluminum base with embedded guide rail for cost competitiveness.

Applications

Ideal for point-to-point micron-level fast positioning in high-speed, high-acceleration, and high-precision scenarios such as laser precision processing, 3C electronics, semiconductor, photovoltaic, lithium battery, glass and LCD panel manufacturing, and precision assembly lines.

Ordering Rules

Product codes specify series, number of movers, motor model, encoder type (magnetic or optical), resolution, cable length, and custom options. Example format: JGE6-L1000-2-34030B2-MRA10-4-D05-***.

Additional Technical Details

Models such as JGE10-B2, JGE10-B3, and JGE12-B3 include detailed dimensions, mounting hole specifications, stroke lengths (50mm to over 1600mm), and weights. Mechanical parameters include resolution down to 0.1μm, repeatability of 0.002mm, straightness, and maximum speeds up to 5 m/s or higher with special bearings.

Motors feature dual movers and through holes for mounting. Hard limits and mechanical stops are specified. CAD files provide detailed design and assembly guidance.

Performance Characteristics

• Maximum continuous and peak thrust forces are specified.
• Acceleration capabilities are calculated using Newton’s law (F=ma).
• Speed limits are primarily constrained by mechanical guide systems, typically capped at 5 m/s but extendable to 10 m/s with ceramic ball bearings or higher with air bearings.

Application Guidelines and FAQs

• Maximum Effective Load: Large loads can be driven with small force if acceleration is low. Sudden power loss causes coasting; brakes on linear guides can mitigate this.
• Vertical Load Capacity: Limited by continuous thrust divided by gravitational acceleration (9.81 m/s²).
• Maximum Speed and Acceleration: Speed limited by mechanical components; acceleration depends on peak thrust and load mass.
• Length Limitations: No inherent length limit; stators and guides can be segmented for lengths over 20 meters.
• Cleanroom Suitability: Non-contact drive with no wear particles or lubricants reduces contamination risk.
• Magnetic Field Effects: Ironless motors have negligible magnetic leakage; iron-core motors have localized fields that decay rapidly and do not cause RF interference.
• Magnetic Rings: Installed at motor leads to filter voltage spikes and protect insulation.
• Hall Sensors: Used for position feedback and commutation, combined with high-resolution encoders for accuracy.
