I have a 220v gear motor left over from my CNC mill conversion that originally was used as a power Z drive. I want to re-purpose this motor to my heavy duty drill press to move the table up and down. The motor was originally switched via contractors and momentary switches. I would like to know if the rotary switch that was used for FWD/REV on the mill motor could be used for this gear motor instead of the contactors. I can fit the rotary switch in the existing electrical box on the drill press. This is the wiring diagram on the grear motor. It has three wires, red, white & black. Looking at the original terminal block the red & white wires had a 6uF capacitor bridged between them. Here is the original rotary switch from the mill. It has 2 wires in marked 2L1 & 2N1 and 4 wires out marked U1, U2, Z1, Z2. I rung out the wires so here are the load paths. FORWARD 2L1 ---> U1 & Z2 2N1 ---> U2 & Z1 REVERSE 2L1 ---> U1 & Z1 2N1 ---> U2 & Z2 My mill did not come with a wiring diagram for the rotary switch. I found one for a Griz mill and it looks like the spindle motor is a 6 wire motor. So is it possible to use this rotary switch on the 3 wire gear motor? If so how would it be wired? Do I need to keep the 6uF capacitor?
