S9350D 390kg Ultra-High Torque Industrial Servo

Precision Engineering for Heavy-Duty Motion

The XQ-POWER XQ-S9350D is a 390 kg·cm-class industrial brushless servo built for compact, high-torque motion systems. Its 7075-aluminium CNC case and compact mechanical format make it suitable for robotic joints, industrial automation mechanisms, and equipment that requires controlled motion within a limited installation space.

The inspection specification records peak stall torque of 320 kg·cm at 24V, 360 kg·cm at 28V, and 390 kg·cm at 30V. At 30V, the listed no-load speed is 0.16 sec/60°. Final system performance depends on voltage, load inertia, acceleration, duty cycle, mechanical leverage, thermal conditions, and the complete transmission design.

Structural Rigidity & Aerospace Materials

The S9350D combines a steel gear, 6 ball bearings, a 25T-φ11.8 mm output specification, and a CNC-machined 7075-aluminium case. The listed dimensions are 68 × 35 × 120 mm, with a listed weight of 690 g. Verify the mounting clearance, output-spline compatibility, servo-arm fit, load direction, and mechanical leverage before installation.

The inspection specification lists no-load current of 200 mA at 24V, 300 mA at 28V, and 400 mA at 30V. Listed stall current is 5A at 24V, 6.5A at 28V, and 7A at 30V. The power supply, wiring, controller, connectors, and protection components should be selected according to the operating voltage and system load profile.

Extreme Waterproofing for Harsh Operations

The XQ-S9350D inspection specification lists an operating temperature range of -30°C to +65°C, a storage temperature range of -30°C to +70°C, and splash-water resistance.

For installations exposed to moisture, dust, vibration, or temperature changes, evaluate the complete system, including cable and connector protection, mounting orientation, sealing, and maintenance conditions. The splash-water resistance specification does not indicate an IP67/IP68 or submersible rating. Confirm the environmental requirements before final product selection.

Frequently Asked Questions (FAQ)

What torque is specified for the XQ-S9350D?

The inspection specification records peak stall torque of 320 kg·cm at 24V, 360 kg·cm at 28V, and 390 kg·cm at 30V. The XQ-S9350D is positioned for 390 kg·cm-class high-torque applications. Peak stall torque should not be treated as continuous operating torque unless the applicable duty cycle has been confirmed.

Which control signal does the XQ-S9350D use?

The XQ-S9350D inspection configuration uses digital PWM command control. Select the required product variant and review its dedicated specification before designing the controller or communication network. The interface of another model or variant should not be assumed to apply to this configuration.

What are the environmental conditions for the XQ-S9350D?

The inspection specification lists an operating temperature range of -30°C to +65°C, a storage temperature range of -30°C to +70°C, and splash-water resistance. It does not provide an IP67 or IP68 rating or establish submersible capability.

Can the XQ-S9350D be customized for OEM or ODM projects?

Yes. XQ-POWER provides OEM/ODM customization services for application-specific motion-control requirements. Share the required torque, voltage, control interface, mechanical installation, duty cycle, and operating environment with the engineering team for product selection or customization discussion.
