Abstract

PURPOSE: To start a motor through the excitation of an armature winding by counting positioning pulses after the rotation of a rotor up to a reference angle with a DC-excitation of one of the phases of the armature winding and a pulse current-excitation of the other.
CONSTITUTION: When an α-phase coil 10 is DC-excited while the motor is stationary, a rotor 12 rotates as shown in the drawing II. When a pulse current is subsequently fed through a β-phase coil 11, the rotor 12 is stationed at θ=0. In order to keep this condition, switches A, B and C are turned on and a switch D is off with a position command pulse generated from a letter position detector 3 for a motor 1. When the switch D is turned on and the switches A and C are turned off at θ=0, a signal from the detector 3 is inputted to a main calculator 6 through a waveform generating circuit 7. The signal is multiplied by a signal from a speed comparator 5 to input a motor driving signal to a power amplifier 8.
