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.

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.

This servo can NOT control the speed, you can only control its direction, please notice this.

Hey,
May I know the screw dimension of the servo screw (not the fastener)?
•Reply •
DFRobot Support • 7 months ago
Mod > Itnet
The screw hole dimension is 4.3mm.

Hi. Is it possible to have the files to open it in solidworks? Can I contact someone to have it?

hi i just bought it , why this servo always rotate? even the program closed? any sugestion? i used raspi 3

This servo is a 360 degree continuous servo, unlike the 180 degree servo

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.

Hi DFROBOT, how heavy is this motor? I need specs on its mass to compute for the FBD kinematics.

Hi the weight of the motor is 60g including the cable connected to the motor.

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?

Mod > Brian Ng
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.

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?

Yes, its a continuous 360 degree motor.

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

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 •
DFRobot Support • 3 years ago
Mod > Marina Uy
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.

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 •
DFRobot Support • 3 years ago
Mod > 3D Printwiz
No, 360 degree servo is like a motor, so it can't hold its position, even when it stop.
•Reply •
DFRobot Support • 3 years ago
Mod
Note: 360 degree servomotor works like a motor, you could control its speed and direction, but not angle.

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.
