I'm trying to get my dc motor and controller wired up so I can put it on my lathe(decided not to put it on my mill) instead of the ac its running. I wired the controller to the motor and it ran, reversed and forwarded, potentiometer functioned but there was a low humming/buzzing sound and something was smoking a little(pretty sure the magic smoke didn't all get out). Shut it off, checked to see if I wired it the same as it was when I first got the motor and it was, however, I usually take pics of wiring(and almost everything else) as I take things apart but this time I made a small diagram and took a picture of that(don't remember why) so maybe I drew it incorrectly. I also discovered that the motor was getting current even when switched to the off position(yikes!! motor smoked a little in the off position, disconnected as soon as I saw it).


The pics should help explain what I did and perhaps get some input from some of you more knowledgeable than I(which shouldn’t be hard).

the motor and controller, the motor has two brown wires(labled A1 A2) and two black(F1 F2), what do the A and F mean?

The controller has a red, brown, white, black and ground connecting to the motor: the diagram/note I made, I'm hoping I mislabeled and that I've reversed connections on two of the wires and its a simple fix, thought I should ask here rather than risk screwing up the motor

Point of reference: you're looking at the red, brown, black and white wires as they enter the controller from the motor.

wiring inside controller, the black and white terminations, the black connects to ac "block" -, the white to whatever that thing is

brown and red both terminate at the on/off, forward and reverse switch which are out of focus but that’s where they connect, there're in focus coming into the controller but not as they go towards the switch

thanks in advance for any help conning my way, Brian

PS really looking forward to having this motor on my lathe!

A=armature and F= field. The armature rotates and does the work so it is usually the larger pair of wires. The field creates the magnetic field around the armature instead of having permanent magnets in the motor. A picture of the terminal board in the controller would be helpful
 
Thanks Contact, I'll get a pic of the board tomorrow. Any one know which is more likely(or possible) to cause the problem, incorrect wiring of the field or the armature? I don't understand(among other things) how the current bypassed the off switch on the controller, seems like whatever caused that is key to solving the issue. Red and brown go from the armature directly to the switch so if I wired the armature wires ion the wrong order would that allow current to go through "open" contact?

first make sure the on off cuts all power..did it have 2 cords on it already..one with a 220 plug?
one out cord

output
2 wires will have a constant voltage when on(field)...other 2 (armature) will be variable
 
Do you have a wiring diagram for the controller? Something is not making sense here.
 
black and red "should " be armature..

white brown should have dc voltage when on and dial at 0


once you get it going..to change direction swap armature wires
 
Answers to questions raised:

yes, 220 plug with power going into the controller, then 1 cord with brown, black, red, white and ground to motor

Jim Dawson Do you have a wiring diagram for the controller? Something is not making sense here.

don't have a diagram and nothing on the inside or outside of the controller

black and red "should " be armature..

I'll change the black to A1 from F2, the brown to F2 from A1 and give it try
