Overview

Based on an integrated development concept, DDSM210 (Direct Drive Servo Motor) integrates an outer rotor brushless motor, encoder, and servo drive into a high-reliability permanent magnet synchronous motor. Its compact structure, convenient installation, stable operation, small size, and large torque make it particularly suitable for applications in the following direct drive fields: robot joints, small AGV drive wheels, self-balancing vehicle drive wheels, and development vehicle platforms for advanced robot projects.

Through optimization of pole number, slot type, air gap, permanent magnet material, and other related parameters, the motor ensures greater torque output, the smaller torque fluctuations, and achieves direct drive at low speeds with large torque, providing users with high-performance direct drive application solutions.

The driver compatible with this motor utilizes the Field Oriented Control (FOC) algorithm, coupled with the motor's built-in high-precision sensor, to achieve precise control of the motor and better noise reduction. The driver features a complete and reliable motor On-board Diagnostics (OBD) monitoring mechanism and protection functions, ensuring the safe and reliable operation of the motor.

Simultaneously, we provide an open-source structural model for this model of direct drive servo motor, which can be downloaded from the "Resources"-"Open Source Structure" section at the bottom.

Usage Precaution

1. Please confirm whether the operating voltage is the voltage specified in this article (5S LiPo, 5s lithium battery (five lithium batteries in series) voltage range) before use.
2. Please make sure the motor is used under the specified environment range (-20℃~45℃), the motor over-temperature protection threshold is 80°C, and the protection is released when the temperature is lower than 75°C.
3. Please avoid immersing the motor in water, otherwise, it may cause abnormal operation or damage to the motor.
4. Please ensure that the wiring is correct and stable before use to avoid poor contact.
5. Please refer to the installation instructions before using the motor to ensure that the motor is installed correctly and firmly.
6. Please refer to the installation instructions before using the motor to ensure that the external output part of the motor is installed correctly and firmly.
7. Please avoid damage to the wire during use, otherwise, it may cause abnormal operation or damage to the motor.
8. Do not touch the rotating part of the motor during use to avoid injury.
9. When the motor outputs high torque, it will generate heat. Do not touch the motor to avoid burns.
10. Do not disassemble the motor without permission, otherwise, it may cause abnormal operation or damage to the motor, and may bring safety hazards.
