Can anyone point right direction
I what to create a conveyer, when the conveyer reaches a certain point(limit switch) it will reverse direction and return home and stop.
I also what to control the speed. Already have a pwm work.
You wan to research 'H-bridge' or 'H-bridge motor control' and you'll find all the information you need.
Use relays if you want but I'm not sure why you would want to? I'd go solid state then you could just 'AND' the direction logic signal with your PWM signal to drive the motor.
A guy at the park had a toy quad-copter that flew pretty far away in the wind then he pushed a button on the transmitter and put it down.
Then the helicopter "reversed direction and returned home and stopped". Of course the helicopter carried a tiny video camera to record the pretty young ladies sunbathing far away.
No, the pretty young ladies were fairly far away sunbathing in the park wearing only bits of green masking tape. They didn't see me coming.
No, they were not playing with my joystick, yet.
To stop the motor you'll want all the H-bridge switches off, and to change direction you just need to change the switching pair.
try reading up on H-bridge motor control, there is plenty of resource on the web and it's really really simple! When you have an idea of how to control the motor we can help with the circuit design details.
Operates on 8 - 20 VDC Extremely high torque output -Rated at 6 oz. in. Stall torque at 12 VDC and 14 Amperes is over 30 oz. in. No load speed of 6600 RPM No load current @ 12 VDC -330 mA Torque output at 12 VDC and 2.5 Amperes is 6 oz. in. 5 pole armature
I need to use it about 100 time aday.
I am usure at what speed until I dod some test but that is more thab enough.
When you stop the motor, does the motor coast and stop past where it's supposed to?
The reason is whether or not one has to employ dynamic braking? I think dynamic braking in this case is best done with the H-bridge. Not all H-Bridges have a "Brake" input.
