VSD kit for small motors in this month's Silicone Chip

(1/1)

bigmini:
This is for those in Australia who have lathes that use induction motors and would like the flexibility that comes with variable speed.

I found that this month's Silicone Chip magazine has an article describing how to build a variable speed drive that suits 3 phase or single phase induction motors up to 1.5kW :dremel:. It's intended for pool pumps to save energy, but I reckon it would be ideal for small lathe owners who have to use their gearbox to get different speeds.

I won't be doing it because my lathe is already variable speed DC, but it might be simpler and cheaper than swapping out the whole motor.
