Help with Stepper Motor and Slip Ring
I need to figure out how to get power and control signals from a stationary computer / PIC into a series of subsequent rings via rotating joints.
Ultimately, what I want to build is a form of motorized gyroscope that can transmit power and control signals to the inner ring motors.
- I'm using a Raspberry Pi 2 to control three Stepper Motors.
- The motors are getting power from an old AC/DC wall adapter.
- I currently have 3x NEMA 17 stepper motors
- Yaw Motor/Axis
- Pitch Motor/Axis
- Roll Motor/Axis
- I've got 2x 12mm 12 8-wire slip rings that I hope can be used to send the control signals from the Controller to each motor.
The problem is that I'm not entirely sure how to connect those components together, let alone how to connect them to bearings to minimize tension on the motor shafts.
(I'm a software engineer, not an EE or ME.)
An example of what I want to build is this:
( However I don't need anything in the middle, I just need a way to control the rotation of each ring layer independently by the stepped motors )
If anyone can point me in the right direction it would be much appreciated,
