DFRobot 2804 3-Phase Brushless DC Motor

DFRobot 2804 3-Phase Brushless DC Motor offers a compact 12V BLDC motor with a high-precision AS5600 encoder, engineered for advanced motion control. This motor operates at a rated 12V and delivers 2600 RPM and 300g.cm of torque, all within an ultra-compact Φ34.5mm x 19.5mm aluminum frame. The 2804 3-phase brushless DC motor provides 12-bit high-resolution angular position feedback, achieving an accuracy of up to 0.087°. This motor supports versatile I2C, PWM, and analog output interfaces and delivers the critical data required for sophisticated closed-loop control of position, speed, and torque. The 2804 3-phase brushless DC motor features an outer diameter of only 34.5mm and a height of 19.5mm, making it suitable for applications with limited space. This motor is an ideal choice for robotics, camera gimbals, and educational platforms.

The 2804 3-phase brushless DC motor is designed for wide compatibility with the open-source ecosystem. This motor seamlessly integrates with the SimpleFOC library, which provides powerful tools for implementing FOC algorithms. The DC motor software support extends to major development boards, including Arduino, ESP32, and Raspberry Pi, lowering the barrier for developers and makers.
