determining motor/pulley shaft

determining motor/pulley shaft

(OP)
Hello,
This is my first post. After reading some of the threads here, I feel under qualified to be here, but I can't seem to find answers anywhere.

I am building a wire winding machine. It seems to be very basic.

I have a Unimount 125 model FO17 electric motor. It is one HP ,60Hz, 575 Volts, 3 phase and reversible. It has a 5/8" shaft 2" long.

I want to know how to determine what size and kind of pulleys, belts, pillow mounts etc. to use. Also, how far apart shout the pulleys be from each other?
The motor will have a pulley and a belt that will turn/ drive a 40" or so long shaft and at each end of the shaft will be a pulley and each pulley will have a belt driving another pulley connected to a spindle. A wire  will have one end connected to a spindle and stretch 40" to connect to the other spindle. The spindles rotate so other wire can be wrapped around  the stretch wire.

Keeping the machine compact would be good. Can the pulleys on the motor shaft be close to the pulley on the 40" shaft?



I want to be able to vary the motor speed as slow as 20 RPM and be able to reverse the motor. Aside from the electrical aspects, how do I choose the correct belt length and distance from one pulley to the other, the correct pulley sizes, pillow mounts etc.
Any help is greatly appreciated
thanks

RE: determining motor/pulley shaft

Most manufacturers of the components you need have extensive engineering literature and knowledgeable people available to help with new designs such as yours.  I suggest you start there.

RE: determining motor/pulley shaft

Can you supply a schematic of the operation via an attachment(step 3)-this will aid in trying to resolve your requirements

RE: determining motor/pulley shaft

A little off topic but if you use a full vector drive, you can control a motor speed down to zero RPM with full torque.  A one HP vector drive will cost under $500.

Everything is already taken care of, if you can find a used glassblower's lathe, that already has driven spindles at both ends.
