Wiring power cable to new motor

Hi,

I am completely new to all this and have just recieved a brand new Peatol lathe + motor. The motor does not have a lead attached and I was wondering if anyone could give some advice as to how to do this. Whether it's something I can do, or if I should seek an electrician. In my naivety, I thought it would be as simple as wiring a plug, but when I unscrewed the top cover I was presented with more terminals than my knowledge could cope with!

I have attached some photos of the motor. If anyone might be able to advice I would be hugely grateful as this is now the only thing preventing me from turning some metal!

Many thanks,

Alex

Hi Alex, your best bet would maybe be to email Peatol machine tools - [email protected]

It shouldn't be any more difficult than wiring a plug, and I'm guessing that the mains will be across the conections with the bars on. You may need to find a stud that connects to the metal frame for the Earth wire though.

Regards Nick.

Alex,

To be brutally honest, if you don't know how to do it, you should ask someone who does; messing around with mains voltages is not a good way to learn. To improve your knowledge, get hold of Jim Cox's books in the Workshop Practice series.

Anyone notice that the motor data plate has a howler on it? 0.18 kW is a quarter HP, not 1.5 HP (or conversely, 1.5 HP is 1.1 kW, but given this is for a Peatol I would assume it's the former, which is also consistent with the mains input current).

I see from your pictures that the six terminals are labeled but they can't easily be seen. The labeling of the terminals is more or less standardised. There is a helpful data sheet here.

Nick's suggestion to email the supplier if you are not sure is best. His suggestion to connect the mains across the connections with the bars is almost certainly incorrect.

I wish I could make a motor giving 1.5 hp for only 180 W input. It would make my fortune and solve the world's energy problems!

Hi Alex ,

connecting the live supply to one link and the neutral to the other will make the motor run

don't forget to the earth wire to the motor frame

it looks like the wires may not be in the original places , the links should make it easy to reverse the Z1 and Z2 connections in order to reverse the motor direction

Hi Russel, you may have misinterpreted my suggestion of the connections, or maybe I've not explained it clearly enough, anyway what I ment is exactly as John Swift has shown in his picture; "as wired in the photo"

Regards Nick.

Alex, please seek advice from an electrician. If you don't know what you are doing, you could kill yourself.

If this is a brand new bit of kit the supplier should be ashamed of themselves. there should have been a sealed plug/lead already attached to the motor. Phone your supplier and raise merry hell and in the process complain bitterly to Peatol. You should not have to go through this process with a new bit of kit. Was there no manual with the machine!

Bob

Sorry, it looks as if you're right. The wires from the windings are not connected correctly. Normally the main winding would be connected between U1 and U2.

Alex,

I would definately give the supplier a b******ing!

Russell.

Many thanks everybody. What a fantastic forum - so many answers in a short space of time!

I think it best to leave the job to someone who is 100% certain of what they are doing. I have contacted Peato. As pointed out by Russell, Bob and John, it looks as if the original wiring may be wrong and seems a little odd that this has arrived without a cable or instruction as to how one should be fixed.

Hopefully Peter at Peatol can give me a definitive answer. Frustrating having the kit and not being able to get going.

Once again, many thanks!

Alex

This motor should be supplied from a motor starter to give overload protection and no volt release, wireing direct to a supply will not protect the motor in the event of a stall or sustained heavy cutting. A fuse large enough to survive the start surge will not protect the motor from overload, a proper overload set correctly should trip before the motor has cooked. The no volt release is for your safety, in the event of an interuption to the supply the machine will not restart while unattended. If the NVR is not installed then when power is restored this could cause damage to the machine if self acting feeds or screwcutting are engaged. The first thing most people do when plunged into darkness is not turn the machine off with the switch you now cannot see but check if the neighbours are in the dark aswell and then find the torches and candles, if you or someone else returns to the machine and power is suddenly restored you may have your fingers in a dangerous place, the no volt release will have turned the machine off for you and will wait for you to restart it.

Thanks, Mike. Wise words - I had read about a motor starter but wasn't sure if it was applicable in my case. Now I realise it is! I think I will get a qualified electrician or motor specialist to set this up as there seem to be too may variables for a novice like me to get wrong!
