More precise speed control, longer life (fewer things to wear out), and much lower electrical noise. They aren't meant to hold a particular position, though, so it probably isn't a good choice for position control. You could use it that way, but probably not very precisely. -Adam On 8/15/06, L030010 wrote: > Hi all > > can anyone please advice me why is it good to use a brushless motor? and if > i need a PID control of position is it a good choice? > > Regards > > > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
