Title: Control system for spindle motor
Inventor: FUJIOKA YOSHIMOTO
IPC: H02P21/24
Filed: 1989-11-02
Abstract: PURPOSE:To prevent the generation of wow and flutter and vibration to enable an accurate contour machining by controlling a spindle motor through fixing a flux command value to a predetermined value at the time of a C-axis control mode when a work fitted to a spindle is contour-machined. CONSTITUTION:A drive mode being now set is determined as to whether the drive mode is a normal mode or C-axis control mode. When the drive mode is determined as the C-axis mode, the flux command value of the set C-axis control mode is outputted as flux command phiC and a vector control is performed by the flux command phiC. Thus, at the time of the C-axis control mode, the flux command phiC is fixed to a set point. As a result, actual fluxes do not vary and a lag from the flux command phiC is eliminated so that no wow and flutter and vibration take place and the C-axis control with high accuracy is made possible.
