Customer Testimonial

German Pool Heat Pump

PFC + Driver Board Case

“Hunovate supplied the complete PFC power and drive solution for our high-end pool heat pump. The sensorless FOC drive enabled ultra-quiet, smooth pump operation, and the high-efficiency PFC delivered excellent EMC performance—allowing us to pass stringent EU regulatory certification on the first submission.”

U.S. Premium Air Conditioner

PFC + Driver Board Case

“Our high-end AC program required exceptional energy efficiency and low acoustic performance. Hunovate’s high-efficiency PFC and FOC drive solution delivered jointly optimized results—achieving leading system-level efficiency while reducing operating noise to a remarkably low level that meets our flagship-grade requirements.”

Welling Motor

Driver Board Case

“As a motor manufacturer, precise drive matching is critical for us. Leveraging its Golden Sample Library, Hunovate quickly identified the optimal parameters, and the customized FOC algorithm fully brought out our motor’s performance. Their rapid response and results exceeded our expectations.”

HILTI Concrete Vibrator

PFC + Driver Board Case

“HILTI equipment demands exceptional reliability. Hunovate’s high-power PFC supply provided a stable power foundation, while the driver board’s algorithms—optimized for impulsive loads—enabled the system to pass rigorous shock and endurance testing, demonstrating outstanding industrial-grade reliability.”

U.K. Lawn Mower

Driver Board Case

“Our commercial high-power lawn mower operates under highly dynamic load conditions. Hunovate’s driver board, with its outstanding torque control and dynamic load handling, ensured consistent power and efficiency across all scenarios. Their professionalism and delivery speed from design to mass production were impressive.”

BLDC Motor Functional Run Test Device for AIP

Driver Board Case

“This BLDC Motor Drive-Based Functional Test Device is integrated as a core module in our standard motor testing system. Its one-button operation enables non-specialist operators to perform accurate tests, while the stable FOC algorithm reliably detects acoustic anomalies and related faults—together providing an efficient, reliable, and standardized testing solution for automated production lines.”
