Hi all...

I need to make a circuit that needs to spin on the shaft of a small dc
brushless motor. I thought I could use a permanent magnet mounted on the
base of the shaft of the motor (not moving) and some coils that will be
spinning on the pcb. I don't know if this will work or provide enough power
(need 5mA) to the spinning pcb . Any better ways ?

BTW I can't seem to find a dc brushless motor manufacturer. Can you suggest
any ?

Thanks
