ODrive Micro: High-Performance, Ultra-Compact Servo Motor Drive for Precise Robotic Motion

ODrive Robotics has introduced the ODrive Micro, an ultra-compact, high-performance servo motor drive designed to simplify precise robotic motion. Building on ODrive’s robust software and hardware ecosystem, the ODrive Micro offers unparalleled integration for next-generation robotic applications. With compatibility for a wide range of brushless motors and an intuitive plug-and-play web UI, it’s never been easier to build sophisticated robotic systems.

ODrive Micro is engineered for easy setup and versatile integration. Its onboard magnetic angle sensor allows for direct mounting on the back of your motor, eliminating the need for a separate encoder. Simply connect it to a 10-30V power source and utilize the convenient daisy-chained CAN connector to get started.

If your application uses a gearbox with an output encoder or cannot utilize the onboard magnetic angle sensor, ODrive Micro also supports hall, quadrature, and SPI encoders. This flexibility allows for both motor commutation and dual-encoder load positioning using external encoders.

ODrive Robotics aims to make precision, high-power motion control accessible and affordable. The ODrive Micro encapsulates a decade of motion control expertise in a compact form factor, delivering up to 180W of power in just 10 cm². This miniaturized version offers the same reliability and performance as the larger ODrive Pro and ODrive S1, making it ideal for applications requiring high precision and power without the bulk.

The ODrive ecosystem supports CAN, offers robust software libraries, and features an intuitive GUI, enabling rapid project setup and execution.

Brushless servomotors outperform stepper motors in power density and have greater service life and reliability than brushed motors. With closed-loop encoder feedback, brushless servomotors provide superior precision, making them the preferred choice for high-performance applications.
