Integrated EC/BLDC Drives for Industrial Liquid Cooling & Data Center HVAC Systems
Published on August 11, 2026
Engineering Challenges in Liquid Cooling
Traditional liquid cooling pumps and HVAC fans face three core bottlenecks:
Envelope Constraints: External drivers waste cabinet space and add complex wiring.
EMI & High Noise: PWM switching generates acoustic whine (>60 dB) and sensor interference.
24/7 Thermal Strain: Continuous operation degrades motor bearings and stator insulation.
Technical Comparison
Feature | External Driver Architecture | MYSUN POWER Integrated Solution |
Footprint | Cabinet-mounted controller | Integrated end-cap drive architecture (compact footprint) |
Noise Level | High PWM whine (>60 dB) | Sinusoidal drive control (low acoustic noise design) |
Protection & Protocol | IP54 / Basic Analog 0-10V | Environmental sealing as required / Communication protocol options |
Key Specifications & Customization
