Description:
The Waveshare DDSM115 Direct Drive Servo Motor is a high-performance, all-in-one Permanent Magnet Synchronous Motor (PMSM) designed for precision motion control applications. With its integrated outer-rotor brushless motor, high-resolution encoder, and servo system, this motor delivers low-speed, high-torque output with minimal noise, making it ideal for demanding robotics and automation tasks.
Built on an integrated development concept, the DDSM115 features a compact, lightweight, and reliable design that simplifies installation and enhances operational stability. Its robust construction and high torque in a small form factor make it especially well-suited for robotic joints, small AGV (Automated Guided Vehicle) drive wheels, balance car drive systems, and custom vehicle platforms.
Whether you're developing advanced robotic systems or prototyping high-precision motion platforms, the DDSM115 offers the performance, integration, and durability required for next-generation motion control solutions.
