Got new single phase electric motor, diagrams and all.
But i'm an architecturally minded engineer and don't know squat about electric diagrams.

Its a 1.1kw single phase Etec ML8022. I just need to know how to wire mains cord to it.

Here's whats in control box:

and here's the diagram on the lid:

Notice there are two stripped multicores sticking out from V2 and U2. I assume its where live goes, but what about ground (green/yellow)? Its bolted into motor body and there are no visible/spare external ground wires etc...

Can someone help me figure this one out ?

Also, could someone help me wire in external direction switch for it, as it goes both ways and i may need to go in reverse...

Do you want the motor to run clockwise or anticlockwise? It's currently configured for clockwise.

Your live goes to V2, and neutral to U2.

Your earth wire connects to the earth terminal, which is the very far right terminal on the top picture.
 
Well, that was quick.

I love diynot :D

CW is what i need most...
How do i wire a switch to change direction ?
 
Short answer is you can't.

There is a way but it's quite expensive, and very complicated, using changeover contactors.

But according to diagram it can be switched to CCW ?
Isnt it a matter of switching over a bar or something ?

I cant read this diagram so i'm just assuming its something simple.

Also, it would not be used to switching "on the fly". Run in CW, turn off, switch, run CCW. No ?

According to the diagram it does look as if you go CCW by moving the U2 bar from Z2 to V1 and the U1 bar from V1 to Z2. Then wiring LNE as suggested.
Should there be that much copper on display?
 
You need to change the position of two links between four terminals.

This can not be done with a simple switch. You need to use two interlocked contactors, and some complicated wiring to do this.

If you really need to be able to reverse the motor, maybe someone can spec up a design and parts list for you.
 
No i dont need it to be switched for the job it does, but its always good to have available options.

This motor goes into a bandsaw, but later i may need to switch it to other machines i'll build...

#UPDATE# Yey, it liiiiiiiives !!!!... Yup, runs fine, and, damn, its quiet... Didnt expect it to be so whisper quiet.....

How do these motors start ? Lout clack and all lights in the house went dim for a moment, then is all good again. Then mighty clack as i turn it off...
Someone care to educate me in this matter ?
 
I think the lights go dim because its meant to be a 3 phase motor, converted to run on single phase with a capacitor to provide the 3rd phase. Someone may correct me though, I'm no expert.
 
The lights dim as this is an inductive load, and when you first power it up, it is effectively a short circuit until the magnectic field gets established.

This is known as inrush current, and is normal.

kinky.
 
Not seen you here for a while. I guess Danielle's gone out for the night? :LOL:
 
Lol nah. Just bored so thought I'd see what's happening here for a bit.
 
Now this is how you derail a thread.
Use phones boys. :D

Is there a way to speed control this motor ?
 
The only way to speed control it would be to use an invertor. This gives you infinately variable speed, soft start, so no more dimming of your lights, and forward and reverse control too.
