Integrated EC/BLDC Drives for Industrial Liquid Cooling & Data Center HVAC Systems
Engineering considerations for integrated EC and BLDC drives used in server liquid cooling and industrial HVAC chiller applications, including drive integration, thermal management, and continuous duty operation.
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.
