This is talked about in series motors when you research on series controllers and motors. Also running a running SEPEX motor with a series controller with a POT this is the way large conveyor systems used to work. |

That’s what I do or did, I was an engineer for a couple of conveyor companies starting back in 1983, I was asked to come out of retirement this past May for a conveyor job at the local Ford Claycomo plant that I am working on now. Before being an engineer, I was an electrician at both of the local GM plants. I worked quite a bit in the control rooms where the drive and control panels are located. I’ve never seen a conveyor drive motor run in series. Most of the DC drive motors I have seen were compound wound motors with both a series field winding and a shunt or separately excited field winding. This may be where the confusion came about. Before that, I was an electrician for a railroad. Road diesels indeed start with the field and armature in series. At about 19 MPH there is a transition from series to parallel for speed. You may be able to run a sepex motor in series but I don’t see getting enough armature voltage to get any speed out of it. |

Re: motor swap
The Sepex field has too much resistance to run in series with the Armature. IT's designed to see full battery voltage. It will not work in series.
I am also an EE. Worked on drive systems way back when. Work on Hard Drives now. |

Re: motor swap
If the two of you were replying to me thats not what I was trying to say.
Sepex motor can run from a series controller armature only, field runs with a large pot or variac. I don't think I said runs in series. conveyors like large mines used sepex motor setup for speed control with above pots and usually once set was left alone. sorry for the confusion |
