Introduction

The direct-drive servo motor is a high-reliability permanent magnet synchronous motor that integrates outer rotor brushless motors, encoders, and servo drives. Using advanced direct-drive technology, these motors eliminate the need for traditional reducers, transforming the previously noisy, inefficient, and bulky motors into compact, efficient, and quiet systems. The motors offer a working voltage range of 11-22V DC, a no-load speed of 210±15 rpm, a rated torque of 0.25 Nm, and a stalling torque of 0.85 Nm. These specifications, along with the high-precision sensor built into the motor and the FOC control algorithm used by the driver, make them ideal for applications such as robot joints, balance car drive wheels, small AGV drive wheels, toy drive wheels, and educational cars.

Integrated Design

The direct-drive servo motors feature an integrated design that combines the motor and driver, providing high integration and a compact structure. This design enables the motor to deliver smooth torque, stable speed, and precise position control without an external reducer.

Low Noise Operation

The direct-drive servo motor has passed noise testing, with a pre-operation noise level of 47.2 decibels and an operational noise level of 54.5 decibels. The brushless motor design ensures low noise and long life, making these motors suitable for applications requiring quiet and efficient operation.

High Precision and Safety

Equipped with a high-precision sensor and the FOC control algorithm, the motors achieve precise control and better quietness. The driver includes a comprehensive OBD monitoring mechanism and protection functions, such as over-current protection, over-temperature protection, and stall protection, ensuring safe and reliable operation.

Advanced Communication and Control

The motors support Hall position detection and electric braking, and can communicate via UART to provide position, speed, current, and fault code information. This feature allows for detailed monitoring and control, enhancing the reliability and efficiency of the motors in various applications.
