The following is based on my many years of motor control design and
It may be a bit of overkill, but you had to ask.
Let's assume the D/C motor operates at 240V, then you need a 2-pole
contractor with a 120V coil and an auxiliary control contact supplied
in a NEMA I enclosure. (This also works for a 120V motor)
At every tool station where you have a D/C pickup, you mount a START
momentary push button station, again in a NEMA I or better yet a NEMA
A single momentary STOP P/B is located at a location of choice.
Any START P/B station starts the D/C.
The D/C keeps operating until the Stop button is pushed.
The system provides under voltage protection.
