Hi All, I'm looking for some guidance in using the brushless gimbal controllers for robotics use so that I can take advantage of all the work that has been done for brushless motor position control. I need to use a water-cooled motor, around 20A per phase so I found: https://aerialpixels.com/shop/brushless-gimbal-controllers/alexmos-32-bit-3-axis-high-power-brushless-gimbal-controller-26v-20a/ It does not seem to be available though - if I find one, is it compatible with the latest software? Has anybody water-cooled this controller (water block over the Mosfets).
I'd like to use it maybe for a robotic arm project.
I was aiming to use a Turnigy AquaStar T20 3T 730KV motor. Do I need to rewind? I would be running it at 6S.
I need to have around 50kg of lifting force at 500mm (250 Nm).
I will have encoders on all axes so I need the latest software correct?
For me the IMU is not really needed but I would have joystick control for all 3 axes. Is that possible or would I need to use the IMU anyways and have the joystick control the IMU "offset"?
You should look for other solutions, some kind of gear box is needed to get 250Nm. Servo motor and controller might be more appropriate for your application.
The motor will be geared down with a belt drive, somewhere between 3:1 and 6:1. I'm not worried about the torque but more the control side and power side.
I do not think that gear ration will be enough. Anyway, as it sounds you just want joystick control and no stabilization, why not use servos (industrial servos) and a servo controller.
INTERESTING ! I am also interested in this what did you decide to do? I am also working on similar project . integrated stop and encoder just like servo and hiy voltage brushless controller here
