I have already purchased this, shipped today. I want to use this in a telescope project.
My question is , can I control speed to a very slow number. I need to get one revolution of the output shaft every 10 minutes. there are approximately 52000 encoder ticks in on revolution. there is a 30x1 or so gearbox on the dc motor.
all I need to know though is can I set speed to a very low number to achieve a rotation once every 10 minutes with that many ticks 52000?
Hi genehunter29009,
What will you use to “send commands” this motor controller ?
The motor controller will change the voltage sent to the motor. To get a slow speed you need to have a low rpm motor / gearbox.
I will be using either my computer Powershell script or an Arduino whichever is easier. Its a telescope motor.
I am just asking can I set the speed to where it moves the encoders 52000 encoder ticks in 10 minutes. Would it be that simple to say move 52000 in 10 minutes. Is that possible or not.
What will be needed is to acquire the Encoder information and drive the motor according to your needs

Thats all l need to know. It does not matter how you control the RoboClaw, what matters is can you control it a slow speeds? can I tell it to move 52000 pulses in 10 minutes.
It’s impossible to answer the question with the information you provided.
A motor controller will change the duty-cycle sent to the motor based on the input voltage. Essentially changing the voltage by putting the controller ON and OFF very fast.
You need to know the RPM of your motor to know the output RPM after the 30:1 ratio.
Also you need to know if your encoder is on the output shaft or the motor shaft.
