HOW ITG LINEAR AND TORQUE MOTORS DRIVE ADVANCED ROBOTICS SOLUTIONS

As the robotics industry advances toward faster, smarter, and more compact systems, motion control has become the core enabler of robotic performance. From precision pick-and-place arms to collaborative robots (cobots), autonomous mobile robots (AMRs), and semiconductor handling systems, the need for high-torque, high-precision, and low-maintenance motors is greater than ever.

ITG Linear & Torque Motor Manufacturer offers a specialized portfolio of direct drive motors—both linear and rotary—that deliver the precision, force density, and smooth operation demanded by modern robotics applications.

KEY APPLICATIONS OF ITG MOTORS IN ROBOTICS

1. Collaborative Robot Joints (Cobots)

Cobots require high-torque, compact rotary actuators with precise feedback for safe human-machine interaction. ITG torque motors, especially frameless and hollow shaft designs, enable:

• High torque in compact form factor

• Smooth and silent operation (ideal for shared workspaces)

• Direct integration into robot joints for reduced inertia

2. SCARA and Delta Robots

High-speed pick-and-place robots operate under demanding cycle times. Linear axes must accelerate rapidly while maintaining consistent precision.

ITG ironless linear motors provide:

• Cog-free, low-mass motion—critical for acceleration

• Precise and repeatable positioning

• Maintenance-free operation for 24/7 uptime

3. Autonomous Mobile Robots (AMRs)

AMRs in warehouses and cleanrooms require precise drive systems and lifting/handling modules. Torque motors provide silent, low-profile wheel drive solutions, while linear motors handle lifting platforms with smooth, jerk-free vertical motion.

Advantages:

• No gearboxes = reduced mechanical noise and wear

• Compact profiles enable tight turning radius and slim designs

4. Semiconductor Handling & Wafer Robots

In wafer processing, die sorting, and probe testing, ultra-clean motion is critical. Vacuum-compatible ironless linear motors from ITG ensure:

• Particle-free motion for cleanroom compliance

• Nanometer-level precision for submicron alignment

• Low heat generation for thermal-sensitive environments

5. Inspection & Assembly Gantries

For multi-axis gantry robots in inspection, PCB assembly, and battery production lines, ITG motors enable:

• Fast multi-axis synchronization

• Precision motion for camera inspection or component placement

• Modular integration with EtherCAT or CANopen control systems

WHY ROBOTICS ENGINEERS CHOOSE ITG

SAMPLE APPLICATION: COBOT ARM ACTUATION

An industrial automation company in Japan integrated ITG frameless TMXSL105 torque motors into the shoulder and elbow joints of a collaborative robotic arm. Combined with harmonic reducers and absolute encoders:

• The arm achieved ±0.02° repeatability

• Reduced actuator noise by 60% compared to geared servos

• Operated 24/7 without lubrication or gearbox replacement

WHEN CUSTOM MOTORS ARE REQUIRED IN ROBOTICS

Custom ITG motor solutions are ideal when:

• Joints or axes have unusual geometry or compact dimensions

• Environmental constraints require vacuum or IP-rated designs

• Advanced feedback (e.g., BISS-C, EnDat) is needed for control loops

• High thermal stability is essential in tightly packed robotic arms
