What is the DDSM400 direct drive servo motor and what are its main advantages?
It is an integrated direct drive servo motor with an onboard driver and encoder, eliminating the external reducer for smooth torque and compact design.
What are the key electrical specifications and performance figures?
No load speed is 400 plus or minus 20 RPM and the rated speed is 100 RPM with a rated torque of 0.15 Nm. The motor draws about 0.24 plus minus 0.07 A and uses a 25.2 V DC supply; weight is 236 g.
How can I control multiple motors at once?
The motor supports LIN bus communication and requires only a single LIN bus line to control multiple Direct Drive Servo Motors simultaneously.
What protection and operating environment should I use this motor in?
It features IP54 protection against dust and water jets and operates from -5 C to 40 C; it also includes over current protection and Hall position sensing.
What is included in the package and how do I install it?
The package includes one DDSM400 unit; chassis or robot chassis are not included. Open source chassis drawings are provided in the wiki and the product supports suspension installation options.
