reconditioning Singer 144W305 motor Cat # S53216E-G

I'm reconditioning a Singer 144W305 30"arm walking foot industrial machine.

Need a wiring diagram for the motor. Came with no cover plate, wires all hanging out.

Thank You: Tim

Can you post photos of the motor and where the wires are hanging out?

I suggest getting a Servo motor, it will save you time and money.

Don't mess with the old motor.  This can be dangerous if you don't know what you are doing.  

And I would recommend a clutch motor 3/4 Horse Power.  Usually 1725RPM, but I've seen 3450RPM as well.  I'd go with the 1725RPM.  Servo is not going to give you the low end torque that your machine needs.

Clutch motors are dirt cheap these days, no one wants them. May be cheaper to replace than to repair in the end.

Greg,

Should not a servo with a small pulley work? I know they come with 3" pulleys, but if replaced with a 2" or smaller, they provide more oomph.

Low end torque on a clutch motor is only useful if you can learn to control the motor - I couldn't.  The usual answer in this case is a servo, small motor pulley and speed reducer (works for me).

I do agree, though, that if it's a very old motor you have to be careful as there could also be damage to the coil windings due to age. Only worth spending the time on if you're determined to try and keep everything original.
