Spindle rotation control system

The system has a speed control circuit 103 which can control motor 104 driving spindle 108 so as to make actual speed AV detected by a detector 105 coincide with a commanded speed CV. … A position control circuit 112 provides a position deviation signal RPD which can be applied to speed control circ...

Zusammenfassung:	The system has a speed control circuit 103 which can control motor 104 driving spindle 108 so as to make actual speed AV detected by a detector 105 coincide with a commanded speed CV. … A position control circuit 112 provides a position deviation signal RPD which can be applied to speed control circuit 103 in place of commanded speed CV (by means of changeover switch 111) so that the circuit 103 controls the motor to bring the spindle to rest at the desired stopping position. … A proximity switch 110 is used which has a magnetic body 110a on the spindle and a fixed sensing portion 110b. At the desired stopping position 110a and 110b confront one another. The switch 110 produces an output of zero volts at the desired stopping position and a positive and a negative output when immediately to the left and the right of the desired stopping position. The signal output of 110 is used to provide position deviation signal RPD.
