Hey Jason,

Love to make the engine when the mill is ready, then implemend it in the rc car.
(only problem is i can`t find a timed belt 4mm wide that cann take the torque!!!)

The 150watt for the Kavo is peak, so it is around 50 watt continues.
The NSK motor 125watt has a cont. torque till 25.000rpm at 2 Ncm, but goes till 50.000.
The maxon motor with the right turns has till 30.000 around 3 Ncm cont.

But most important, the Nsk motor costs here 950 euro and 780 for the drive (125watt, max 30krpm)
The e3000 drive is 1800 euro alone.
The Maxon setup is around 240 euro over here, nice for the student.

With rc brushless there are 2 problems in my opinion,
the shaft runout is to high and the bearings not preloaded.
The drive doesn`t has a function to keep the rpm and no good adjustments.

The maxon is preloaded and a max. runout off 0.02 mm, the drive has speed or current control.
Also a nice pot with 1024 steps.

The coupling will be a very tight pressed fit balanced ground + adapter.

When my max. feed will be around 1200mm/min the rpm can be a bit lower,
no max performance and no hurry for me, but i will have money to eat.

The strategy in cam will be important, but my nice Unit of Solidworks and Solidcam 2007 with HSM, will do,
think i will enjoy making the G-code!!!

The machine will be non commercial.

Still thinking about the spindle, maybe i buy the nr-3060s, but it is expensive.
In my configuration it will be very overdimensioned and will last.

Kind regards,

Roy B.
