Compact Three Phase Brushless DC Motor With Integrated Encoder For High Speed Precision Motion Control
The 2804 three phase brushless DC motor is a compact high performance solution engineered for advanced motion control systems requiring high speed smooth torque and precise position feedback. Operating at a rated twelve volt supply this motor delivers up to two thousand six hundred RPM while maintaining a stable three hundred gram centimetre torque output in an ultra compact aluminium housing.
This motor integrates a high resolution AS5600 magnetic encoder that provides twelve bit absolute position feedback with approximately zero point zero eight seven degree accuracy. Designed specifically for Field Oriented Control applications it enables exceptionally smooth quiet and efficient motor operation. The robust hollow shaft construction combined with FOC optimisation makes this motor ideal for robotics camera gimbals balancing platforms and educational motion control development.

Integrated High-Precision Magnetic Encoder
The AS5600 magnetic encoder incorporated into this motor is key to its precision. This component delivers 12-bit, high-resolution angular position feedback with an accuracy of up to 0.087°. It provides the crucial data needed for advanced closed-loop control of position, speed, and torque through its diverse I2C, PWM, and analog output interfaces. This integration eliminates the need for separate encoder mounting and calibration, which simplifies the design process.
Optimized for Field-Oriented Control (FOC)
The combination of the brushless motor and the high-resolution encoder makes this unit ideal for FOC. Field-Oriented Control, an innovative motor control algorithm, uses accurate feedback to adjust the magnetic field, resulting in astonishingly smooth torque delivery, low operational noise, and higher energy economy than previous control approaches. When combined with a compatible driver, such as the SimpleFOC Mini, it creates an integrated platform for designing high-performance motion systems.
Compact and Robust Construction
The motor has an exterior diameter of 34.5mm and a height of 19.5mm, making it ideal for applications where space is limited. The enclosure is CNC-machined from aluminum with a black anodized finish to provide structural integrity and good passive heat dissipation. The design includes an outer rotor with NdFeB strong magnets and a hollow shaft, which allows for wire routing and the integration of additional components along the motor's axis.
Broad Compatibility for Rapid Development
This motor is intended to be broadly compatible with the open-source ecosystem in order to speed up project development. It works perfectly with the SimpleFOC package, which offers powerful tools for implementing FOC algorithms. This software support extends to key development boards like as Arduino, ESP32, and Raspberry Pi, making it easier for developers and creators to integrate powerful motor control into their projects.
