  • National Backend Motors

    Hey everybody, I have 3 spare National backend motors for even number pinspotter. Is it possible to switch the wires inside to change the rotation for an odd number pinspotter?

        The rotation can be reversed... now if I can just find the paper that has the motor pinout and wiring instructions, I could even tell you how to do it... [img]/content/btubb/images/%%GRAEMLIN_URL%%/mad.gif[/img]

          Just Switch the 2 wires on the Switch That the Incoming power is going to? Best Guess for now

            Some are, some aren't. I forget why. Call Stahls, they know how. [img]/content/btubb/images/%%GRAEMLIN_URL%%/cool.gif[/img]

                i do not tink it is possible. i have tried everything (switching wires and having it rewound).i talked to amf and they agreed that there is not a way to reverse a national motor but you can do that to westinghouse motor but i never tried iy on ge.

                    I don't know of a way personally to reverse a national BE. The Franklin replacements we've been getting have instructions right with them as to how to reverse it, quite easy and quick, ya just switch 2 wires, but I dunno of a way to do it on an original national
                    All I want in life is to turn wrenches and climb around pinsetters/pinspotters again :/

                      Re: National Backend Motors

                      There is a way, because if you exchange one with Stahls, the rebuilt one you get back is reversible.
                      But nobody seems to know how to do it except Stahls.
                      That's probably a good reason why they get the money to rebuild them and make them reversible!

                        <font size="2" face="Verdana, Helvetica, sans-serif">Bamm is correct, you cannot reverse direction on National B.E motors. I wish we could thats all I have.

                          I can change them all without a problem but then I have Leason and 220 Volts.
                          I did change one other stator(dunno what brand)by reversing the centrifugal switch--capicitor--start winding line; one side is on the terminal board, the other side is on the coils connected with 3 other wires (2 main winding wires and a wire going to the terminal board), you have to find the right wire by disconnecting the wires and measure them.
                          I have even changed a national combi motor in a BE motor when I was in desperate need...
                          Good Luck

                          So it goes.

                            I will get out my manual toomorow and tell you guys the wire colours and locations. It's not hard i used to only have one spare so we were always swapping it.
                            First you clean it
                            then you lube it
                            then you clean it
                            then you adjust it
                            then you clean it
                            then you clean it some more

                              The reason Stahl's can reverse a BE motor rotation is they put on one of their solid state start switches. They purposely manufactured them with that capability. It's the only way I know of to reverse a true National motor.
