I’m looking for a servo motor and drive. The motor should be small-ish - industrial strength or high torque not necessary, I’m basically turning a hamster wheel. I want to provide a voltage signal to the drive to dictate the position of the motor shaft at certain times, and then intermittently I need to toggle the motor to torque mode and apply zero current so the motor shaft spins freely.
Can you point me towards a good motor/driver pair?
Nothing immediately comes to mind.
Normal RC servos rotate 180 degrees based on RC input.
Continuous rotation RC servos can rotate continuously based on RC input, but you cannot assign a position.
Most smart servos allow for continuous rotation, and positioning (normally ~300 degrees), but require serial input. You can get a torque reading.
A DC gear motor with encoder will provide relative as opposed to absolute position and needs a microcontroller.
Can you describe your project a bit more?
