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.
