PURPOSE:To permit the stabilized high speed operation by means of a small and light weight motor by a method wherein a circuit is installed to previously decide the period of the angular momentum obtained from the motor acceleration and deceleration characteristics. CONSTITUTION:The momentum A(A0-A3) is given to the momentum circuit 1 by the set pulse P, and the output B thereof makes the zero detection circuit 5 activate to generate the signal Q to the phase excitation circuit 6, and then, the circuit 6 permits the driving circuit 7 to operate and to rotate the motor 8. The signal B and the signal E incoming from the travel completion circuit 4 which stores the momentum of the motor are put into the acceleration generating circuit 2 where the optimum starting acceleration and the stop acceleration are previously programmed to be provided, thus, the momentum period decision circuit 3 sends out the demultiple output D0-D1 through the acceleration command signal C and the clock N. The demultiple output D0-D1 subtract the momentum circuit 1 and also subtract the travel completion circuit 4. |
