Product Description
The CT BLDC2475 is a compact 5-24V 75W sensorless brushless DC motor driver controller designed for small three-phase BLDC motors. It supports stable speed regulation, forward and reverse rotation control, brake functionality, and external stop control, making it suitable for robotics, cooling systems, automation devices, DIY motor projects, spindle applications, and embedded motion control systems.
This BLDC controller adopts a sensorless drive solution, eliminating the need for Hall sensors while maintaining reliable motor operation for compatible brushless DC motors. The integrated potentiometer speed control allows smooth motor adjustment, while the compact PCB structure makes installation convenient in space-limited applications.
Ideal for robot drive systems, cooling fan motors, hard drive spindle motors, small electric machinery, and engineering development projects.
