HSW Series Liquid-Cooled Direct-Drive Motors

HSW Series liquid-cooled direct-drive spindle motors deliver high-efficiency, instantaneous torque for heavy industrial manufacturing applications.

We do not rely on third-party assembly. Our in-house manufacturing process ensures that every HSW motor is built with a modular design, reducing manufacturing complexity while guaranteeing precision and consistency.

  • Advanced Liquid Cooling Architecture: Integrated internal liquid cooling channels rapidly dissipate motor heat via a precise temperature control system. Compared to standard air-cooling solutions, this improves thermal dissipation efficiency by 50%+, supporting sustained heavy-duty operations without degradation.

  • Extreme Overload Capacity: Built for punishing environments, our direct drive motors exhibit a significant 2–3x overload factor for both power and torque.

  • Uncompromising Efficiency & Control: Engineered for variable frequency speed control and FOC (Field Oriented Control) sensorless vector control. This ensures high instantaneous torque delivery alongside remarkably low energy consumption.

  • Ultra-Compact Form Factor: By utilizing segmented winding and a high slot fill factor, we achieve an ultra-compact size and reduced weight.

  • Optimized Thermal Materials: We utilize custom high-thermal-conductivity insulation materials that actively reduce thermal resistance while maintaining absolute structural strength.

Engineering Sizing Note

When specifying a motor for your facility, precision sizing is critical. For applications involving heavy-duty operations or sudden heavy-load conditions, our engineering team strongly advises selecting a drive one to two power ratings higher. This ensures the system can comfortably withstand abrupt high-current surges without triggering thermal faults.

  • Textile & Printing Automation (HSW 181): The HSW 181 series delivers the smooth, ripple-free continuous operation required for air-jet looms, precision circular saw machines, digital inkjet textile printers, and PVC printing presses.

  • Heavy Industrial & Resource Conveying (HSW 220): Engineered for high continuous torque in severe environments, the HSW 220 series powers oil extraction pump units, heavy mining conveyors, industrial sawmills, and primary textile processing equipment.

Technical FAQ: HSW Liquid-Cooled Direct-Drive Motors

Why should we upgrade to liquid-cooled direct-drive motors instead of traditional gearbox systems?
By eliminating mechanical transmission components such as belts, gears, and couplings, direct drive motors deliver power directly to the load. This results in zero mechanical backlash, extreme positioning precision, and a drastic reduction in maintenance costs. Furthermore, our liquid-cooled architecture ensures absolute thermal stability during high-speed, continuous operations, preventing the heat-induced deformations common in air-cooled setups.
What is the overload capacity of the HSW series during sudden heavy-load operations?
Industrial environments are unpredictable. Our HSW series is engineered with a significant overload capacity, safely handling a 2–3x overload factor for both power and torque. If your application involves frequent, abrupt high-current surges (such as in mining conveyors or heavy metalworking), our factory engineers recommend selecting a drive one to two power ratings higher to guarantee uninterrupted performance.
How much more efficient is your liquid-cooling system compared to standard air cooling?
The integrated internal liquid cooling channels in our spindle motors are managed by a precise temperature control system. This advanced design improves thermal dissipation efficiency by more than 50% compared to traditional air-cooling solutions. It rapidly pulls heat away from the core, supporting sustained heavy-duty operation and protecting the rare-earth magnets from thermal degradation.
Can the HSW spindle motors be integrated into our existing CNC machine tools?
Yes. The hollow-shaft variants within the HSW series (such as the A4, A5, and A6 configurations) are designed specifically for seamless, frameless integration. With rotor inner diameters ranging from 60mm to 90mm, they integrate directly into advanced turn-mill compound machines and turret lathes, minimizing the physical footprint while maximizing mechanical output.
Do you provide direct engineering support for sizing and retrofitting?
Absolutely. As an independent manufacturing brand, we do not outsource our engineering. When you choose our liquid-cooled direct-drive motors, you get direct factory-to-floor technical support. We provide complete 3D CAD dimensions, performance curves, and custom sizing consultations to ensure the motor perfectly matches your dynamic load and spatial constraints.
