Hi guys,
I am in Australia, recently I have purchased my first machine, it's a S1 Bridgeport Vari-speed.
Much like most people who decide to build the RPC, I am tossing up between idler motors.
I'm a robotics engineer so understand electronics however 415VAC is not an area I have spent much time working and this voltage is less-friendly to trial and error for obvious reasons
To help clarify my decision, I was hoping someone with more knowledge could assist.
1. 3 Phase motor selection.
- Does the idler motor have to be 240/415V wound ie: can I use a 415VAC induction motor like TECO 3 PHASE ELECTRIC MOTOR 5.5 kW 1440RPM - 380/415AC 12.4/11amps 38mm shaft | eBay
I note there is only a delta rating at 380-415VAC.
2. Is there any advantage or disadvantage to running a certain pole count/RPM?
3. What practical numbers to guys look to build to ie: 5.5kW idler will happily power ##kW of downstream power?
Thanks for any help!
