Inverter

Thanks very much for your comments

Screwed chuck? Using a braking circuit? Not a good combination. Unless you have some means of preventing the chuck unscrewing, during rapid deceleration, you may have been lucky ... thus far.

Thanks very much , plenty of options

Can anyone recommend where to buy an inverter that has good back up service ?

Drives Direct of Nottingham.....Dave has supplied me with numerous Imo/Teco drives, never let me down.

Alternatively, Invertek are a UK designed/built/supply company with suppliers in the UK. Got my two from Engineers Mate.

Had a query, contacted Invertek direct and got the answer I was after.

Thank you very much John

I've fitted four of these HuangYang VFD for about £100 each for my Model Engineering friend. One has been in regular use for more than four years and not one has given any trouble. I think a lot of mythology exist about home workshop inverters, after all, few if any are working to tight schedules and do we actually need all the facilities some of these expensive industrial inverts offer. I have a preowned inverter on my Super, so old it has dip switches and was originally supplied by RS. I use slow speed when screw cutting and no signs of the motor over heating. Also no signs of the chuck becoming loose or off after switching of after a high speed run, could be I'm fortunate. John

Is there much to fitting them John ?

I fitted a tec motor and inverted inverter to my lathe front inverter drive.com all went together nice and easy. The machine is much better to use

They wire up as easy as any other vfd. The challenge comes in the form of interpreting the Chinglish manual when dealing with the setting parameters. It can be more of a challenge for the less technically minded.

I believe one or more forum members has a set of parameters that will make the inverter work as required. Perhaps they will make themselves known via this thread?

I could work them out if I had the manual in front of me, but cant remember them all from memory/experience..

One of the things I liked about the HY inverters is the fact that the output stages are using discrete components rather than a module..Repair option is more feasable... If/when needed.

It's sounding to technical to me, I'm going to have to get help setting one up.

No problem....Tell us which inverter you go for...I'm sure the collective will have you up and running....

Thank you John, very much appreciated

Hello Paul, if you go down the HuangYang VFD I'll send you a copy of the program which I used for my friends. By the way, there now is a youtube thingy which explain the programing things very well. I'm sure members will be only to glad to help you in any way as required. As for the motors, my friend picked up second ,hand motors very cheaply, which only needed the brass links moving to convert from Star to Delta. As the control voltages are very low a home brew control box can be made. Unfortunately Maplin has now gone which was a good source for variable resistors and switches. However, ESR at Cullercoats have almost the same range of components needed. John

ESR is just up the road from me.....Very good supplier of components, Steve and Anthony are very helpful...if you need advice..

Thank you very much John, if the right three phase Lathe comes available I don't think I will have any worries about running on an inverter

Where abouts is that ? I'm in North Lincs

Your way up north !

I went with Transwave no problems wiring/setting up the documentation that came with the unit was easy to understand I did need to ring Transwave with a question which Peter answered so 3 years later no issues

Thanks Harry, I've just had a look, I thought they just did the old fashion type
