In
order to improve the stability and reliability
of
motorized spindle when it is running , the simula-

of
motorized spindle is approximately circular, sö
the motorized spindle can have less harmonic in voltage and current
, thereby it can reduce the vibration and
heat when motorized spindle is running. This controller for motorized spindle drive control system is feasible
to satisfy the rapid responding requirements
of
speed control

motorized spindle using for processing , and
the effectiveness

of
motorized spindle in the control system modeling is solved through this simulation verification.
