RollerCAN Unit is a brushless DC motor motion control kit with multiple integrated control functions, designed for efficient motion control. It supports 6-16V DC power input (via the CAN (XT30) interface) or 5V input (via the Grove interface) and can automatically adjust the power factor to ensure optimal performance. It features a built-in FOC closed-loop drive system, using a 3504 200KV brushless motor. The maximum continuous operating phase current is 0.5A without forced cooling, and 1A for short-term. The driver uses a magnetic encoder for feedback and supports current, speed, and position triple-loop control, ensuring precise control. The unit’s shaft can optionally include a slip ring, allowing the Grove interface on the top to remain connected with the bottom, supporting 360° rotation while expanding additional modules at the top. This ensures power and data transmission through the rotating part.
