Reply To: RC Brushless spindle motor



That’s a very good point about torque been more important than speed.

The only reason I was planning on using 12V was I could use a server power supply with no extra mods.

Im gona leave the motor and power supply for the time tho, and concentrate on the housing and bearings.
Iv got an big slow heavy 24V 150w brushed motor that i use for my mini lathe that i will use for first bench tests of this spindle. The speeds will be no where near what will be seen during operation but will be a good firt test before I splash out on any new electrics.

Do you have any advice on housing design?
Current plan is just a lump of aluminium with a couple of bearings pressed into either end. Just need to make sure the bearing pockets are conentric and square.
