Inverter wiring Again

Hi Folks

I have recently bought a Viceroy TDS with a 3 phase motor and to run
it from my domestic mains I`ve bought a inverter.
I have read some earlier posts regarding inverter wiring and I have
hopefully understood most of it.
I`m looking for some specific help to my own setup.
Ok here goes:
The motor is a Hoover (made in Scotland) and has six terminals
arranged as below


FRONT OF MOTOR/PULLEY

2 3 4 5

1 6

As bought the wiring was as follows

Pins 1,3,4 were connected to each other.

Pins 2,5,6 all had a red wire attached.

After removing the jumper plates the following had continuity

Pins 1 & 5 continuity

Pins 2 & 4 continuity

Pins 3 & 6 continuity.

From earlier posts I think I have to connect together the pins with
continuity i.e Jumper pins 1 & 5 together, jumper pins 2 & 4 together
and jumper pins 3 & 6 together. Is this correct?

If so, is it Ok to use wire jumpers as oposed to the plates as the pin
configuration makes using solid links akward?

The inverter is a Telemecanique Altivar 11.

I`m ok with the mains in and the additional control box but I need
some advice on the connections to the motor.
The terminals on the inverter are:
U/T1 on the diagram connected to U1 on the motor
V/T2 " " V1 "
W1/T3 " " W1 "

So basically I need to know which pair of termials relate to U1, V1 &
W1?
Also does it matter, if the terminals are jumpered together, which of
the pair the the supply wire is connected to i.e. in the pairing of 1
& 5 could I connected to either 1 OR 5?

Thanks for reading this rather long post and I hope I have supplied
enough info.

Cheers

Paul

Paul, do you have any information from the motor's rating plate? Is the
inverter a 'normal' type, i.e. Vin =230V and Vout =230V.
Assuming the motor is a 230V/440V type and the inverter is 230V out, you'll
need to wire it for delta operation.
Assuming that the motor ran as it was wired before, then 1,3 and 4 were the
star point, so the windings are 1(A)-5(A'), 3(B)-6(B') and 4(C)-2(C'); you
want to connect A toB' B to C' and C to A' and connect your power to the 3
points A, B and C (you can interchange B/B' for C/C' if the links are easier
to connect). Nearly all motors I've seen have the terminals arranged so that
the links fit directly between opposite pairs of terminals to make wiring up
more simple, e.g.
1 3 4
| | |
6 2 5
This arrangement looks a little odd as far as the numbering goes, but if
your's is arranged similarly then the chances are it's right.

Re: Inverter wiring Again

Hi Martin

Yes the inverter is 230V in 230v out.
Sorry I forgot that bit.

Motor is 230/440V 50Hz 1125RPM

Yes the motor ran as I saw it under three phase power.

So basically I connect

1 to 6
3 to 2
4 to 5

I can then connect my 3 wires to ABC i.e.

1
3
4

Does this sound OK or have I got it wrong?

Also does it matter if A,B, or C are connected to U,V or W from the
inverter?

Thanks again

Paul

Hi Paul, yes that sounds OK. You can connect U,V and W in any order; if it
runs the wrong way, swap any two of the U, V or W wires around so that
forward on your inverter matches forwards on the lathe. A quick check, after
you've wired it but before you connect the inverter, is to measure the
resistance AB, BC and CA, they should all measure the same within a few %.

I'm no expert on these matters but it seems to me that jumpering pins as
listed, e.g. 1 to 5, would short out the three coils.
A typo or am I missing something?

Martin's reply does not show connections like that and makes more sense.

Re: Inverter wiring Again

Hi Henry

Yes I think you are right. The continuity would a coil so as you say
I think it would not be good to connect those pins together.
John S posted a pic of a before & after inverter job but the pins on
that motor were in a different configuration than mine and I think I
misunderstood the info being presented.
After reading Martins reply it seems a little clearer now.
I`m certainly no expert on electrics and least of all 3 phase.
I think if I follow Martins instructions I should be Ok but any more
info advice gratefully received.

Thanks again to Martin for the replies.

Paul

Hi Martin

I`ve connected the jumper plates as above i.e

pin 1 connected to pin 6

pin 3 connected to pin 2

pin 4 connected to pin 5

All the links do fit with no problems.

I checked the resistance directly from pin to pin with no wiring yet
attached (only the links) and got the following:

A To B (pin 1 to pin 3) around 20 ohms

B to C (pin 3 to pin 4) around 20 ohms

C to A (pin 4 to pin 1) around 20 ohms.

All resistances are the same give or take 1/2 ohm.

Does this seem OK?



Cheers

Paul

That sounds OK Paul.

I always feel that thinking of the diagrams of star (or Y) and Delta
helpful. Separate all windings and then reconnect either a star or delta.
Delta voltage is always the lower voltage to the two settings. This is
logical looking at the diagram.
Star voltage is root 3 * delta voltage. Simplest just to remeber this than
try and understand.

Irrespective of the configuration, swapping any one winding end for end with
respect to the others will just reverse rotation as will swapping any pair
of wires between the motor and the inverter. Most inverters will allow
swapping primary direction of rotation in a menu somewhere so that 'forward'
can be defined as normal for the application and reverse being the other
way.

Good Luck

Bob

Re: Inverter wiring Again

Hi Folks

Finally found some time to sort out my inverter wiring.
A big thanks to Martin for your help and advice which proved to be
spot on. Also thanks to Bob for his contribution.]
Inverter is up and running and everything seems fine.
If any of you are going to Warwichshire in October I would love to buy
you a pint!

Thanks Again

Paul
