Wiring my 8 pole motor

[Jacus]

Hi everyone

I'm new to this forum page. I live in the new forest in Hampshire and I'm in need of some electrical support please.

I bought a new 8 pole induction motor and I haven't a clue how to wire it up to the mains. I need the motor to turn anti clockwise if possible as I'm working with my kids to make a plastic extruder machine.

I will attach some photos to give you guys an idea. Any advice will be much appreciated. !

Your motor is wired in delta.
Connect your 3 live wires to each of the 3 terminals U1, V1 & W1.
The 2 blue wires are probably for a thermal overload.
This would be wired in conjunction with a contactor, to cut power to the motor if it over heats.

Hi spinlondon

Thanks for the message. With regards to wiring the 3 live wires into U1 V1 & W1....can I wire them into any of the ports? Are we talking about the normal 3 wires...blue , yellow and brown?

Sorry if the questions sound a bit daft but I don't want to cause an electrical fire or issue.
If you say my wiring is Delta, does that have anything to do with the rotation?
Many thanks

The motor is shown wired in Star configuration for a 400v 3ph supply. Connect the three phase 400v supply via a suitable starter to the terminals marked U1, V1 & W1.
The two blue wires are a thermistor, this will need a seperate Thermistor relay that will detect the change in resistance of the thermistors if the motor overheats. This relay then trips the motor starter.
If you wire it up and it goes the wrong way, simply swap two over any two of the incoming phases.

Yes star, sorry. Don’t know why I said delta?
No, not Blue Yellow and Brown.
Should be Brown Black and Grey.
Needs a 3 phase supply.

Aplogies if you do, but based on your responses. Do you understand that this motor requires a 3 phase supply?
You won't have that at home.
It will also require a DOL starter with a 0.63A range thermal overload relay.

You have a motor which will operate in Delta at 230v or Star at 400v. Unfortunately both these modes of connection whether 230v Star or 400v Delta require a three phase supply. It sounds like you only have 230v single phase and hence it will not operate.

 

[Jacus]

Thanks for clearing it up. So I really have the wrong motor.

 

[ian.settle1]

If you have only a single phase supply you will need a single phase to 3 phase converter 2.2KW Hi-Torque Static Converter - Motors and Inverters - https://www.motorsandinverters.co.uk/product/2-2kw-hi-torque-static-converter/

 

[Jacus]

Thanks Ian. Will check it out.

 

[Andy-1960]

He could buy a 230v single phase to three phase variable speed drive and connect the motor in delta.
That would then run off a domestic supply

This would be much better. Your motor would have to be delta configured.


WEG CFW100 0.18kW 230V 1ph to 3ph AC Inverter Drive, Unfiltered - AC Inverter Drives (230V) - https://inverterdrive.com/group/AC-Inverter-Drives-230V/WEG-CFW100A01P6S220/

Beaten by Andy.

You would also require the EMC filter and appropriate cabling.

 

[TJ Anderson]

Not sure how much torque your application requires, but if you cant return the motor you can actually make it run on a single phase supply simply using 2 capacitors.

This may work in a classroom but for practical applications it is not really feasible.

Bit confused here,on nameplate it says a connection @ 230 v in delta,is that possible.
Needs the wiring diagram to be certain.

Yep, has to be 3 phase 230v. Some of the smaller variable speed drives on the market are single phase input at 230v, three phase output at 230v.

Ok thanks

When the three-phase motor is delta connected, the capacitor is star connected. Running capacitance: refers to the starting capacitance. After closing the switch K, the power is switched on and the motor starts running. When the motor reaches the rated speed, the c1 shall be disconnected through the switch K, otherwise the motor will generate heat or even burn out.

better off to buy a single phase motor.
