It supports servo motors (the mainstream choice) and stepper motors (for light-load, low-precision scenarios). Servo motors are compatible with multiple brands including Mitsubishi, Panasonic, Yaskawa, Delta, and Inovance, meeting the power and control protocol requirements of different brands.
The power of the servo motor should be selected according to the module load and operating speed. For example, the GTH4 is compatible with low-power motors ranging from 0.1 to 0.4kW, while the heavy-duty GTH12 model needs to be paired with high-power motors ranging from 0.75 to 1.5kW.
Four standardized mounting structures are available to adapt to different equipment space layouts:
Exposed Mount: The motor is directly connected to the end of the module, featuring a simple structure and excellent heat dissipation. It is suitable for scenarios with ample equipment space.
Left-fold / Right-fold Mount: The motor is laterally connected to the screw via a coupling, which can shorten the axial length of the module and is ideal for compact equipment.
Bottom-fold Mount: The motor is installed facing downward, effectively reducing the overall height of the equipment and applicable to vertically installed automated production lines.
The motor and the module screw are connected by an elastic coupling, which can buffer vibrations during operation, compensate for coaxiality errors in installation, and avoid screw wear or positioning accuracy drift caused by rigid connection.
Some high-precision models support the optional configuration of rigid couplings to further improve transmission response speed, suitable for scenarios requiring high dynamic accuracy such as laser processing and precision inspection.
For module models with built-in brakes, servo motors with brake function can be preferred to achieve dual locking of "motor brake + module brake", enhancing safety in vertical installation scenarios.
The GCH/ECH series dedicated to dust-free environments can be paired with dust-proof motors to prevent dust pollution in clean rooms caused by motor operation.
