dont know if this is the right place to post this question.
i have this lathe but dont know if the motor is good how do you guys go about checking to see if the motor is any good.
thanks

What kind of motor? 1 phase? 3 phase? DC?
If just a regular 1 phase induction motor, power it up and see what happens?
What makes you think it needs checking?

its a 3 phaze motor
I dont know much on motors I just opened the spice box and there were all these leads coming out so I was woulder when you put a meter how do you check it. this is a lathe
How many leads and are they marked in any way.
What does the name plate say? 220/440 dual voltage?

thanks for the reply and sorry for not replying and earlier.
so this is what I gather from the motor name plate
HP: 7.5 RPM: 1725
VOLTS: 230/460 AMPS :22/15
PH: 3 HZ:60
also I open the motor splice box and it has 9 wires.
the way the are connected goes like this
4and7
5and8
6and9
1is by itself
2is by itself
3is by itself.
my question is still can I plug this in my home garage and how can I do it.
thanks for all the help.
It looks like it is a dual voltage star connection in both speeds.
You cannot check it on a regular domestic 1 phase supply, unless a phase converter or a variable frequency drive is used.

thanks for the info really appreciated.
I am not quiet sure on what you mean but bassicaly what your saying is I need a phase converter and a variable frequency drive to check it.
please bare with me I am not a electrician I just want to know what I need so when I do call a electrician he does not try to bulls_ _ t me around.
any ways thanks for the help if you have any more suddjestion please let me .
all I really whant to do is put the machine in the garage and put a variable frequency drive and make it run.
thanks
I would prefer a VFD know that you know my motor nameplate
I am going to get a VFD.
can you give some pointers on what kind I should buy also where ,
I have thought about EBAY.
but I dont know what I should look for.
thanks again :cheers:
That is a fairly large motor for 1 phase input, look for around a 10hp that will accept 1 phase at 220/240 input.
Some here have bought the Toshiba or Fuji.
I have picked up Mitsubishi, WEG, or Telemecanique off ebay.
If getting second hand, make sure it has the program pad otherwise you would have to purchase separately.
