PROBLEM TO BE SOLVED: To prevent the vibration of a motor and exclude possibility of step-out at the time of changeover from the acceleration and deceleration control to the constant speed rotation control of a motor, in control equipment of a pulse motor. SOLUTION: Motor control equipment is constituted of a control pulse generating means 206, which generates pulses for controlling the rotating speed of a motor 203 and generates pulses changing pulse duty for changing pulse period, a control signal generating means 207 for generating signals deciding the rotating direction of the motor, an exciting pulse generating means 205 for generating exciting pulses whose number is the number of positive phase and negative phase to be excited of the motor from pulse output of the control pulse generating means and a control signal of the control signal generating means, a constant current control means 204 which controls a motor current to be a constant, and a constant current value deciding means 208 which detects change of period of pulses from the control pulse generating means by integrating the pulses and decides the control value of the constant current control means in accordance with the detected result. |
