Manxmodder:
Cheers for the info mfletch,very much appreciated. That seems a really good quality unit and the manufacturers 5 year warranty is very reassuring as well.
I've been considering reinstalling the original 3 phase motor and a speed controlled inverter for a while now.
I look forward to seeing what setup John chooses to install on his new140....OZ.
John Rudd:
Oz, the vsd that Fletch linked is for a 240v 3phase motor.....Your orig motor may not be suitable if it's the original .....check the name plate to see if its dual voltage.....star 415v or delta 240v.....
mfletch:
Yes the motor on my L6 is a dual voltage so it can be changed between star and delta 240v or 415v

John,cheers for the reminder about star and delta,I was planning on having a look at the motor before making any purchase of a VSD.
Looking at the motor options for the L6 in the owners handbook there are various specs of motors depending on the spindle speed ranges,which differed on certain models.
The optional motor specs given for 3 phase 50 hz are:
(single speed 1500rpm motors)
1.5 hp 34-750 rpm spindle speed
2 hp 45-1000 rpm " "
(Dual speed 1500/3000 rpm motor)
3.5 hp 34-1500 rpm spindle speed
3.5 hp 45-200 rpm " "
The spindle speeds chart on my lathe shows 45-1000rpm so it follows that the original motor is 2 hp.
mfletch just for interest,what spindle speed ranges does your L6 have,and is it a MK 1 version?......OZ.
mfletch:
Mine is a Mk1 its had a replacement motor {not by me} 1500rpm 3HP; speed range 45-1000rpm
sorry John for the hijack
