Publication number: 20240113648Abstract: A motor control apparatus includes: a converter circuit; an inverter circuit; a current detector; a regenerative resistor; a regenerative resistor controller; and a control device. The converter circuit converts alternating current from an alternating current power supply to direct current, converts regenerative direct current from the inverter circuit to regenerative alternating current, and further supplies the regenerative alternating current to the alternating power supply. The inverter circuit converts the direct current to alternating current for driving a motor, and converts regenerative alternating current from the motor to the regenerative direct current. The regenerative direct current from the inverter circuit passes through the resistor. The regenerative direct current passes thorough the resistor upon the current detector detecting the regenerative current exceeding a predetermined value.Type: ApplicationFiled: September 27, 2023Publication date: April 4, 2024Inventors: Yuji IDE, Michio KITAHARA, Shunichi MIYAZAKI, Toshio HIRAIDE
