Selecting A Motor For Centrifuge

Can anyone please advise me in selecting a single phase motor for a centrifuge? I understand that a capacitor start motor is best for applications requiring a high starting torque but am unsure of what size motor or any starting arrangements that would be required.

The centrifuge rotor is 5” in diameter, weighs about 2 kilos and has to be spun at around 8000 rpm by a V belt drive.

I don’t mind doing a bit of experimenting if given a good starting point

PS. Can anyone point me in the direction of a few motor suppliers with decent prices?

Cheers
Ian.

Diy Vfd For Washing Machine Motor

Hi all, I am building a Centrifuge for separating water and contaminants from oil and was thinking of using a washing machine motor directly coupled to the central shaft to avoid a wasteful gearbox or belt drive.

Can anyone provide me with a circuit for a simple VFD circuit to drive this motor to between 8,000 & 10,000 RPM or give me any pointers in designing my own?

PS, I have an electronics background but have no experience with AC Motor control.

Any help much appreciated.
