Need Wiring Help For 12 Volt Motor

bertie_bassett:
sorry not the best description on my part.

is there any other info with the pwm board? need to know whether the output (motor) -ve is common to the input -ve , hopefully it is or what i drew up last night is wrong
if theres not further info it should be easy to inspect and/or test to find out.

also the way iv drawn things will put 12v onto the motor output + terminal, i dont think this will cause a problem, but the board may not like it. so need to check befor we go much further.

in fact, scrap that diagram, just realised it wrong and will go bang, sorry will have another think and try again

bertie_bassett:
also just thinking about a few ideas, and would you be happy having to use one stick to get things moving in a direction, then the other to override the speed?

so you'd select left with the latched stick and the motor would move left at the set speed, if the momentary stick was then moved in either direction the motor would continue to move left but at a faster pace, as soon as the momentary stick was let go the motor would slow back down to the set speed.

bit hard to describe but should work as follows:

latched joystick left, momentary joy stick in neutral, :- motor moves left slowly

latched joystick left, momentary joy stick in moved in either direction, :- motor moves left fast

latched joystick in neutral, momentary joy stick moved in either direction, :- nothing happens

it might make the wiring a bit easier but youd not be able to just use the one stick for rapid traverse. i think its how the milwaukee i used to use at work was set up.

vtsteam:
If you add a switch for ON/Off, this is what I come up with using your parts:

Please check before using.

Also please fuse the power supply positive before the switch.

Thanks for your help guys. Problem is I'm somewhat baffled when it comes to schematic diagrams. I'll see if I can figure it out in the morning.

Hi
simpler way is to add wires to the pot on the controller middle terminal and the High speed side of the pot and a closed switch will give full speed.
Use the relays one for forward and one for reverse controlled with one joystick and the other one to short the wire on the pot.

Remember to allow the motor to STOP with the mains power switch off before reversing
