Abstract
PURPOSE:To obtain a motor regeneratively control circuit capable of reducing the capacity of a capacitor by connecting a series circuit of a resistor and a switch in parallel with the capacitor, closing a switch at the regenerative time and absorbing the energy by the resistor. CONSTITUTION:Power transistors (Tr) 4-7 are conducted ON or OFF with pairs of Tr 4, 5 and Tr 6, 7 by driving circuits 15-18. When the Tr 4, 5 are conducted ON, the current of the motor is increased, and when they are interrupted OFF, the capacitor 14 is charged via diodes 12, 13, and these operations are repeated, thereby charging the capacitor 14. When the motor 9 is regenerated, pairs of the transistors Tr 6, 7 and pairs of diodes 10, 11 are energized in reverse direction, and when the capacitor 14 is raised higher than the ordinary charging level, a switch 20 is operated by the voltage detector 21 to connect the resistor 19 with the capacitor 14 in parallel, thereby absorbing the regenerative energy of the motor 9 by the resistor 19.
