AIR COOL INDUSTRIAL CO., LTD.

Systems and methods for monitoring, regulating, and diagnosing the performance and health of pumps and fans, including speed control, flow rate management, abnormality detection, and safety mechanisms like overspeed safeguards.

Development of novel motor architectures beyond traditional radial flux designs, including linear, axial, or multi-armature configurations, often to optimize for specific performance characteristics like torque density or form factor.

Focuses on optimizing the geometry, structure, and internal flow channels of impellers, blades, and housings to improve fluid dynamics, efficiency, or specific performance characteristics of centrifugal pumps and fans.

Compact and lightweight lighting devices designed to be worn on the body or easily carried, often featuring ergonomic designs, integrated power sources, and adjustable illumination.

Methods and circuits for controlling the power electronic converters (inverters, bridges) that supply current and voltage to electric motors, including switching strategies, voltage command generation, and multi-phase configurations.

Techniques for determining the rotor position, speed, or other operational parameters of an electric motor without dedicated physical sensors, often relying on back-EMF, current, or voltage measurements.

Optical structures and lens designs that improve light extraction efficiency from LED dies and modules, including diffractive films, micro-lens arrays, reflectors, and color-conversion layers.

Strategies and circuits for optimizing the supply and consumption of electrical power for motors, including current limiting, regenerative energy handling, battery integration, and managing power quality.
