Description:
The DDSM115 Direct Drive Servo Motor with Wheel Hub is a high-performance, all-in-one Permanent Magnet Synchronous Motor (PMSM) designed for demanding applications requiring high torque, low noise, and precise control. Combining an outer rotor brushless motor, encoder, and servo in a compact package, this motor eliminates the need for a traditional gearbox by utilizing advanced direct drive technology, ensuring zero backlash and ultra-fast response.
With a noise level below 50dB and support for multiple operating modes, including current loop, position loop, and velocity loop, the DDSM115 is highly versatile. It also features RS485 communication, making integration into robotic, industrial, or fitness equipment systems seamless.
The motor delivers low-speed, high-torque performance, with a rated torque of 0.96 Nm and a locked-rotor torque of 2.0 Nm, making it ideal for home robots, commercial robots, and other precision machinery. Its robust IP54-rated design ensures reliable operation in varied environments.
