Abstract

PURPOSE:To shorten stopping time largely by putting on the DC brake on an AC motor, by restricting DC current passing winding of the AC motor by holding chop motion of an output transistor of an inverter in a certain condition by stopping motion of inverter action. CONSTITUTION:When inverter action is stopped after a distribution holding system 3 and a brake current restricting system 4 were added to a transistor inverter, a transistor distributing system 1 of the inverter is held in a certain condition, and because of the DC current passing three windings 17-19, only a stator of an AC motor is excited by DC current restricted by a brake current restricting system 4, and therefore, a brake action occurs between the stator static field and a rotor turning by inertia.
