Schaublin 125-CNC retrofit.

Sorry, my mistake, its a 4 and 8 pole Dahlander motor.

Bummer -- guess the foot print sizing thing means a bar feeder and chip conveyor are not going to happen .:laugh:
See that ZincBoy has posted the SSR Bd. schematic an parts listed --#201613
One 48 volt centrer tap Xfmr could power the conntactors an also the 24 -12 and 5 volt DC power.

hmm,
where is 1:2 transmission to get the 3000 upm at the spindle ?

On my mill I get the voltages < 24 from a bunch of DC-DC converters.

This style, with digital display of input and output voltages:



Currently three of them, 12V for the PC, 5V for the Mesa cards and 4.2V for the Ikea LED lights.

Electrically switching from 8 pole to 4 poles on the motor.

Thanks, you have posted those before. Look pretty good, and I will consider them, altough Din Rail transformers are now cheap as well, and I wouldn't have to muck around designing and printing a housing.
