Compact brushless motor gear speed regulator test module Compact design enables quick detection and adjustment of motor positions in tight spaces. Userfriendly knob provides manual speed regulation without the need for remote control devices. Wide applicability with signal input for effective speed regulation, suitable for brushless power fans and other small systems. Easy connection thanks to an integrated stepdown circuit that supports direct connection to battery configurations from 1S to 6S. Key benefits Saves space while delivering reliable, handson speed control. Simple, onhand adjustment with a knob; no external controller required. Flexible power options from 1S to 6S, reducing the need for additional regulators. Straightforward integration into existing brushless motor setups and test benches. Use scenarios Prototyping small drones or robotics projects: connect to a 1S6S battery, use the knob to finetune motor speed and observe response on the bench. Regulating cooling fan speed in compact electronics enclosures, such as small HVAC units, RC equipment, or 3D printers. Bench testing geared brushless motors in hobby projects or educational experiments, enabling rapid speed adjustments without separate control hardware.
