How to stop two DC motors simultaneously using limit switches

I need some help – I'm building a machine but I'm not sure of the best way of doing it.

Thanks a million for your help

Just to refresh my point – I've made one or two changes

I have two large wire spools. One empty and one full. The full spool (approx. 500kg) is much larger than the empty spool (100kg when full).

I wish to transfer the wire from the large spool to the smaller spools. I want to do this regularly so I want to set up a system that will not have to be monitored but can turn itself off when the smaller spool is full and/or the larger spool is almost empty – whichever happens first.

I want to keep this as simple as possible.

I'm looking to put a motor on the small spool and use this to turn the large spool through the pull of the wire

I will be using one small spool at a time along with one large spool at a time

I want the entire system to shut down once the small spool is full or the large spool is almost empty – whichever happens first

The wire in question is a high carbon wire with a very high tensile strength so this should not be a problem for the wire – I am confident hat the wire will be able to handle the pull as long as there is a slow start up and slow down

The large spool has a weight of 1100lbs (500kg), a diameter of 28 inches (70cm) and a depth of 12 inches (30cm) – in the picture attached there are two large spools stacked on top of eachother on one pallet

The small spool has a diameter of 19 inches (48cm) and a depth of 9 inches (24cm)

I want to unwind the entire contents of the large spool onto 5 smaller spools – each smaller spool will be manually lifted off and replaced with an empty spool each time the small spool is full – maximum rotational weight on the take up spool at any one time is 220lbs (100kg)

I would like to start and stop the small spool slowly – ideally a slow start/stop lasting approximately 3 to 4 seconds

I would like to turn the small spool – the one powered by a motor at between 3 to 5 revolutions per second (180 to 300 rev per minuet)

A uniform wrapping speed is not critical – I am conscious that the wrapping speed will change as the diamter of the larger spool decreases and the diameter of the smaller spool will increase. I don't need any footage count – just plain transfer from one spool to another

I do not have any motors at the moment so any suggestions would be greatly appreciated

I have access to 110 Volt, 230 Volt and 3 phase 400 Volt supply

I don't need the motors to run in reverse just in one direction

I'm hoping to get this done for as cheap as possible – at most €1500

Please give me some suggestions on how to start and stop both motors and the best type of motors for the job

Thanks very much for your help
