Hi ive just bought a Titan DC Gearhead Motor 12V 1000 RPM HP, i did a bit of reading up on the RPM and torque limits and this one looked the best for my usage
I am looking to power a threaded rod on my lathe so that my tool can automatically move up and down it. I would require the motor to run both ways
I was wondering what is the best way to power this motor? There may be sawdust around so i was thinking a small 5 amp 12v car better but not sure if that is suitable and would make it easier for swapping the + and - wires over for reverse
Also i was wondering if its easy to wire up to a switch that will do forward and reverse or potentially something that could also control the speed(like a knob controller). Would that be a simple wiring job or require something more complex)
As far as I can understand, you will need a motor speed controller too. But I cannot find a suggestion. The video embedded here Titan DC Gearhead Motor 12V 1000 RPM HP - RobotShop says ‘Pro877 Control Board’ in the description in Turkish. But I could not find anything after searching this keywords. I hope Robotshop team will help.
@Ste1337 Welcome to the RobotShop community. The stall current for the motor is 5.9A (12V), so ideally you need a motor controller which can handle about 1/3 of this value (napkin math not knowing exactly how much current your application will actually draw, but if it’s over 1/3, then you’re pushing it too much). Therefore to control speed and direction, you’d ideally need a motor controller which can operate at 12V and provide up to ~2A.
Something like this might work well for you, but as you said, you’ll need to enclose it to protect it from dust etc.:
So that product will control the current/voltage and allow me to control speed and forward/reverse with the switch and knob? Is it safe to hook up a 5amp 12v car batter(small one) to power this?
Do you have any recommendation for an enclosure? As a woodworker all i can think of is building a box and sealing the holes for the controllers with sillicone perhaps?
Q1) So that product will control the current/voltage and allow me to control speed and forward/reverse with the switch and knob? Is it safe to hook up a 5amp 12v car batter(small one) to power this?
Indeed, should be fine.
Q2) Do you have any recommendation for an enclosure? As a woodworker all i can think of is building a box and sealing the holes for the controllers with sillicone perhaps?
Not really. Wood seems a bit overkill. If you can, try to find a plastic box which is slightly larger and drill appropriate openings.
Q3) Would something like this be suitable as a power source? I am struggling to find anything suitable with a UK plug on it
It says max 2A for that wall adapter, so it’s likely not suitable unless you’re running the motor without much resistance.
Thanks for the advice, sorry for the slow replies i received the items about a week and a half ago.
Ive connected it all together and it seems to work perfectly, the only problem is it cuts out when it tries to drive the shaft.
Im wondering if i perhaps need a stronger motor this one is rated at 7.5kg/cm (0.75Nm)
The shaft is 1.6m long 12mm stainless steel threaded rod with some resistance from guided square bearings in a square tube (it is quite a tight fit and needs to be for holding the lathe cutters).
Would you know how much torque cut out rating i would need? Anything high torque seems to be of a lower speed 200rpm or lower and ideally i need around 1100rpm. I would imagine something similar to a cordless drill motor would work but not quite sure what i should be looking for.
