Description
Specifications

Based on the integrated development concept, DDSM115 is a high-reliability Permanent Magnet Synchronous Motor (PMSM) integrating an outer rotor brushless motor, encoder, and servo. With a compact structure, it is easy to install and can be operated stably. As it is small while with high torque, it can be applied for the following advanced robot projects such as robot joints, small AGV drive wheels, balance car drive wheels, and the development of vehicle platforms.

By optimizing the number of poles and slots, slot type, air gap, permanent magnet material, etc., it is ensured that the motor has greater torque output and smaller torque fluctuations, and realizes direct drive with low speed and high torque, providing users with high-performance direct-drive application solutions.

As the drive for the motor adopts the Field Oriented Control (FOC) algorithm and works with the built-in high-precision sensor, the motor can be precisely controlled with lower noise. The driver also has a complete and reliable OBD (Onboard diagnostics) monitoring mechanism and protection functions for the motor to ensure safe and reliable motor operation. At the same time, Waveshare provides an open-source four-wheel drive off-road vehicle structure model for this type of direct-drive servo motor.

Key features

Ultra low noise
High precision and zero-backlash
Fast response, direct drive without delay
Integrated motor and driver, compact structure and high integration
Provides smooth torque, steady speed and accurate position without an external reducer
Supports RS485 communication mode, only 1-ch RS485 bus is required to control multiple direct drive servo motors at the same time
Motor feedback information such as position, speed, current, error code, etc. can be obtained through communication.
Multiple operating modes: current loop mode, position loop mode, velocity loop mode
Excellent low speed performance: the DDSM115 speed is as low as 1 RPM and its torque up to 2.0Nm
With Hall position detection, over-current protection, etc.
Supports electric brake
Waterproof & dustproof: IP54 protection rating, the ingress protection provides a longer lifetime and better performance
No drive mechanical friction, drive efficiency close to 100%
