BUY NOW INTRODUCTION This is the most powerful standard servo sized motor from DFRobot so far. The DF15RSMG equips with two pairs of the servo shells. One is a stardard shell with four M4 mounting holes. And the other one includes a shell with double bearing which is specially designed for the application of the robot arm or the joints.The shells of this kit are thickened to make it stable enough for motion system. The torque of this motor is about 19kg.cm at 7.4v power supply.Using the Arduino servo library, you could drive this servo motor easily.To reduce the consumption of your microcontroller, this servo has a lock function for the pulse detection. So driving it to a target position just requires one PPM controlling signal. NOTE: This Servo Motor is not a servo which allows you control position or speed, but it is actually a motor with servo appearance, and you can control its rotating direction. You could use servo.h to make the adjustment.

Jan * 5 months ago Dear DFRobot team, I bought 2 of those continious servos. I wanted to use them on different speeds. But it didn't work, I could not adjust the speed. My programm works with other continious servos. May you know what the problem is?Best regards Jan. * Reply * Share DFRobot Support Mod > Jan * 5 months ago This servo can NOT control the speed, you can only control its direction, please notice this. * Reply * Share Itnet * 7 months ago Hey, May I know the screw dimension of the servo screw (not the fastener)? * Reply * Share DFRobot Support Mod > Itnet * 7 months ago The screw hole dimension is 4.3mm. * Reply * Share Florian Baraban * 9 months ago Hi. Is it possible to have the files to open it in solidworks? Can I contact someone to have it? * Reply * Share Teguh Isron Nugraha * a year ago hi i just bought it , why this servo always rotate? even the program closed? any sugestion? i used raspi 3 * Reply * Share DFRobot Support Mod > Teguh Isron Nugraha * a year ago This servo is a 360 degree continuous servo, unlike the 180 degree servo * Reply * Share Teguh Isron Nugraha > DFRobot Support * a year ago ya i know, the problem is the servo can't stop rotate even orange wire (PPM input wire) not conected, i must take vcc or ground wire manually to stop it. i found a solution, i replaced a PCB board or encoder on servo. i replaced it and it return to normal. im sorry DFROBOT i think the encoder is broken. thank you for your attention. * Reply * Share francisbautista * a year ago Hi DFROBOT, how heavy is this motor? I need specs on its mass to compute for the FBD kinematics. * Reply * Share wendy > francisbautista * a year ago Hi the weight of the motor is 60g including the cable connected to the motor. * Reply * Share Can this motor be used with brushed ESC? im planning to connect it to the brushed ESC which will be connected to the receiver, no arduino will be used. Is that compatible? Brian Ng * 2 years ago * Reply * Share Mod > Brian Ng * 2 years ago It depends on the control signal, Servo is 4Khz 500us~2500us. And 360 degree servo are special. it control the speed only, not the position. DFRobot Support * Reply * Share Brian > DFRobot Support * 2 years ago Is this a continuous 360 degree motor or does it rotate and stop at 360 degree? if it just 360 degree, is the motor able to be modified so that it rotates continuously? * Reply * Share wendy > Brian * 2 years ago Yes, its a continuous 360 degree motor. * Reply * Share Leff Wei * 2 years ago Tested on Arduino Leonardo (Romeo DFRobot) without external power supply, if you add a torque, make sure to give an external pwoer supply. #include <servo.h> Servo myservo // create servo object to control a servo void setup() { myservo.attach(9) // attaches the servo on pin 9 to the servo object } void loop() { myservo.write(0) //Max rotation in clockwise delay(2000) myservo.write(93) //STOP, 93 is tested when servo drawing 4.8V from arduino, should be 90 theoretically see more * Reply * Share Marina Uy * 3 years ago Can an encoder be used with this motor easily? Is so, which one is best and how is it attached? Is there a product specification document for this motor? * Reply * Share Mod > Marina Uy * 3 years ago HI, I am sorry, there is no encoder for this motor now. And it is a 360 degree rotation servo. The control method is similar to the standard one, but work as motor. DFRobot Support * Reply * Share 3D Printwiz * 3 years ago I understand that it does not have angle control, but does it stop on the dime, say my code specify an amount of time it runs, and stops, and does it hold its position. * Reply * Share DFRobot Support Mod > 3D Printwiz * 3 years ago No, 360 degree servo is like a motor, so it can't hold its position, even when it stop. * Reply * Share DFRobot Support * 3 years ago Mod Note: 360 degree servomotor works like a motor, you could control its speed and direction, but not angle. * Reply * Share raul > DFRobot Support * 3 years ago So...A motor specially designed for the robot arm or joints, shouldnt have angle control?... so u cannot really have any feedback from the position? Thanks. * Reply * Share DFRobot Support Mod > raul * 3 years ago Right! 1 * Reply * Share ALSO ON DFROBOT ESP32 Arduino Tutorial: Controlling a buzzer with PWM ESP32 Projects: Mail Alarm 2 comments * 5 months ago 6 comments * 7 months ago DFRobot Support -- Can you use different resolution like 13 DFRobot Support -- https://github.com/espressi...
