Good morning,
I’m planing to buy an herkulex DRS-0402 to build a prototype but I need more informations.
Do you have Torque(RPM) graph ?
If it fits to our needs we would ask for more of them.
Thank you
Marc-Andre
Hi Marc-Andre,
First, welcome to the RobotShop forum.
There is no proper Graph available for that motor but a lot of useful information are available in the user manual.
HERE is a direct link to the DRS-0402 manual
You can find software and manuals HERE
Hope that help,
Thank you Dialfonzo but I’ve already read the user manual.
I can’t understand how someone can buy a motor without even knowing it’s “true” torque… Stall torque is just useless to know… you never buy a servo motor for it’s holding power… Anyway…
thank you for answering me
Marc-Andre,
Understanding your needs, it would be useful for you to have a Torque VS Current graph.
Most application with servo need holding torque information as they are in fact holding position (Like in a robotic arm application).
We have asked for such graph from the manufacturer and will get to you once they reply.
Ok, thank you so much for your professionalism Dialfonzo, I await your reply.

Hi Marc-Andre,
We had a reply about our information request, but they are not able to provide the specification.
Instead they gave us available information about the motor used in the servo.
Here is their reply:
After I checked your request with our R&D, I came to know that we did not have exactly matching information.
Instead, I got some information about Faulhaber motor’s specification and related graph. (Not servo motor’s one. We are using Faulhaber coreless motor for our DRS-040X/060X servo motor.)
If your customer wants to know its current consumption, current consumption of the Faulhaber motor would be 2.5A when we input 12V and current consumption of control board would be 0.05A. (total approx. 2.6A.)
You can refer to the attached information though it is not exactly same thing what your customer want to see. (he can find some clue).
Files are in attachment here on the post.
We hope that help a bit,

Hi Dialfonzo and thank you for your answer,
I’ve read the informations you gave me but it didn’t help me that much.
Actually, I need a servo that could hold 4 N.m (40kgf.cm) but as [font=Arial, Verdana, Tahoma, sans-serif][highlight=#f1f1f1]Nominal torque (continuous torque).[/highlight][/font]
Do you have anything like this ?
Thank you
Marc-Andre
Marc-Andre,
If you want to stay in the Smart Servo range, you might want to look at Dynamixel servos.
Dynamixel MX-28T Smart Serial Servo (TTL)
Dynamixel MX-28R Smart Serial Servo (RS-485)
If you don’t care, look at this one, it’s a VERY powerful and big servo motor.
Torxis i00600 12V High Torque Servo Motor
My bad I was talking about 4 Nm and not 0.4 Nm. The last one could be the one I’m looking for.
Thank you Dialfonzo, I’ll let you know if It fits to my needs.
