  1. Hi Dave, Some motors like yours when they are...

    Hi Dave,
    Some motors like yours when they are manufactured have their coils designed to operate from 415v or 240v. If they are 240v coils then they can be connected in Star so they would operate...
  2. Hi Dave, To start with that motor most probably...

    Hi Dave, To start with that motor most probably is internally connected delta, that means the coils are 415v. So there is a VFD that inputs 240v and outputs 415v 3 phase. I don't know anything other...

    Hi Tim,
    The Shaper's motor rotation should be to give a quick return after the cutting stroke.

    Hi nimi55,
    I'm glad you have sorted this motor out. Yes, more than likely it is as you say first switched into high then already running switched into low.

    Hi Richard, It looks like we are about to build an R.P.C, and you will be very pleased with it's performance. Maybe you will buy the transformer unless we can come up with something but I think a...

    Hi Richard, Generally speaking, you need a transformer. I would not worry about that other post where that person asked for some assistance and would not respond to the questions asked. I think he...

    Hi N, If you want to build a Rotary Phase...

    Hi N, If you want to build a Rotary Phase Converter that you can plug and play, I think it would be better to build a 240v single phase input with 415v 3phase output, because most 3phase things you...

    Hi CBudz, I have already said I have built several higher voltage type converters. It was said on this forum a few years back that there was only 3 persons on here that have said that they have built...

    Hi C Budz,
    I am going to assume that the network supply voltage in your part of the world is 230v/400v so I also assume your machines that require 3 phase are 400v/415v.I realise some smaller 3...

    Hi C Budz
    What is your supply voltage? and what voltages do your various machines 3 phase motors operate from?
    If this is your hobby and you have the ability to build, I think you should build it...
  13. Motor Identification and Use. Help Please

    I think as a young teenager I saw a motor like this on an oil burner for the hot zinc tank at a galvanizing factory. Looking at it's terminal block, and the two internal switches, I am curious what...

    Hi Tony,
    I own this Myer Mechanical Laboratory Jig Borer. I have had it for more than 30 years. It is complete except for the belt guard for the pulleys on the boring spindle. This machine came...

    Hi Ted, Thank you for your response. I thought my machine might have been from around the turn of the Century but when looking at the image of the blue Slotter (1856) in the Science Museum Group...

    Hi Street,
    I have looked on there and I can't find anything relevant.

    If the idler motor is 15hp as stated, it will be 415 volt Delta connected for continuous Duty, that means the 3 coils in the windings will be wound for 415v. So transformer will be required.
    And it...

    Hi Krankieone,

    You asked for some "bright ideas". If you could post a picture of the rating plate of your 15hp Idler,I will be able to tell you why your RPC is not running your 3hp Lathe motor.

    Hi Krankieone,
    Would you post a picture of the 15 hp Idler motor rating plate and are you using a transformer.

    Hi Nick,
    When you say you converted the motor to single phase do you mean you fitted a new single phase motor, or, you converted the existing 3 phase motor with a phase converter to run from single...

    Hi Nick,
    I think your problem is you are doing what the above poster did and getting no results.
    Well that Hofmann Machine is 230volts 3 phase, so if you were to change that 3 phase motor to a...

    Hi dbooth. I am assuming at the house you moved from you had this Lathe connected to a 415 volt 3phase service. Very few houses in Australia would have R.C.D protection on a 3phase circuit in a...
