Richmond Radial Drill wiring?

Hi Ronnie,

I can tell you what I think some of the items in the control box are.

Starting at the top left. Below the panel with the the screw terminals and fuses I think there is a transformer from 440 V to 110 volts for supplying the coils on the contactors. (Contactor is just another name for heavy duty relays.) The transformer does look a little on the large size just to supply the coils on the contactors. To the right of this there is a vertical metal panel which looks like it may have some components fixed to it. If this is the case they could be a delay circuit for star/delta starting. The item at the top and just to the right of this panel is a relay. The two square things on the top right look like selenium rectifiers. (If they are they will consist of many metal plates with spacers between them mounted on a threaded rod.) The other four items look like contactors. As there a four I suspect the motor may be a two speed type. (Only two contactors would be required for the star/delta starter.) I would not suggest connecting the supply to the terminals A, B, D without getting someone to trace out the wiring diagram. The two fuses are probably for the transformer so the non transformer end of these should go directly to two of the incoming phases You will probably find this end of the fuses go to two of the three sets of contacts on one or more of the contactors. If there are more than three sets of contacts used on the contactors then some will be connected to the control wiring and hence eliminated from the three phase wiring. I suspect you will need someone with electrical knowledge to help you. I live about 200 miles from you so I cannot offer to help. I must complement you on providing enough information (Including you location.) to enable people to try to help you.
