Members Happy Hooligan Posted July 16, 2014 Members Report Posted July 16, 2014 I have an older Singer clutch motor 105-125 volts 60 cycles HP 1/2 PH. 1 model 9-996196-03 and it's going the wrong way for the machine I have It also has a big singer transmitter instead of the usual on/off switch. It has three wires, red, black, white and they're attached to the red, black, white (with green on black) to the motor. How do I re-wire it to go in reverse? thanks! Quote
Moderator Wizcrafts Posted July 16, 2014 Moderator Report Posted July 16, 2014 I don't know how to reverse the wiring, but I do know how to reverse the direction of the belt: twist it once into a figure 8! I did that on my Fortuna skiver's clutch motor. It reversed the direction and caused no trouble for the last year.

Don´t know how your motor is wired and if it has a capacitor nor not but when I work on our German Pfaff, WEG, or Kobold brand clutch motors (all set up with capacitors for 220V singe phase) you just have to switch one cable in the junction box. But don´t ask me how this works on your certain motor, I´m not an electrician.

Members Constabulary Posted July 16, 2014 Members Report Posted July 16, 2014 This is how it works on the above mentioned clutch motor when run on 220V single phase with delta connection and capacitor - not sure if it looks the same on yours. otherwise this Video should give you an idea: Quote ~ Keep "OLD CAST IRON" alive - it´s worth it ~ Machines in use: - Singer 111G156 - Singer 307G2 - Singer 29K71 - Singer 212G141 - Singer 45D91 - Singer 132K6 - Singer 108W20 - Singer 51WSV2 - Singer 143W2
Members Joon1911 Posted July 16, 2014 Members Report Posted July 16, 2014 If the motor corresponds to most modern motors you should be able to just reverse your black and red leads. That SHOULD reverse the direction of the motor. White should be neutral, both black and red should be hot. You can check with a multimeter or even one of the "dummy" current checkers that you can get at your local hardware store similar to this: http://www.homedepot.com/p/Klein-Tools-Non-Contact-Voltage-Tester-NCVT-1/203578320 With the motor plugged in the black and red wires should have current and cause the tester to ping, white should not.
