摘要： An electric motor (1) is driven by an inverter amplifier (2) through a cable (5). An absorber (3) is built in the electric motor (1) to suppress and absorb a surge voltage generated due to the surge impedance mismatch between the cable (5) and the electric motor (1) as well as a high-frequency noise generated due to the switching operation of a switching element in the inverter amplifier. The absorber (3) is made up of a plurality of conductors, each of which has a predetermined length and is covered with an insulating material. The conductors are connected to the input terminals (4a, 4b, 4c) of the electric motor (1), respectively. The forward end of each conductor of the absorber (3) is either open or connected to one or more other conductors through a member of a high impedance. The surge voltage and the high-frequency noise are suppressed and absorbed by the absorber.

摘要： An inverter apparatus is provided with first and second current detectors for detecting the current of two arbitrary phases and further with first and second A/D converters, and they are integrated into one unit. It furthermore stores, in a storage device, a compensation value for compensating for an unbalance between gains of the first current detector and the first A/D converter, and gains of the second current detector and the second A/D converter. By multiplying the detected current value of either one of the detected phases by this compensation value, it equalizes the current feedback gains for both phases.

摘要： A motor driving apparatus including a regeneration control function and a power storage device for accumulating a regenerative current and for supplying an inverter section with electric power during acceleration. The inverter section is connected to a converter section by a DC link to which regeneration start detecting means and the power storage device are connected. When the regeneration start detecting means detects that a voltage at the DC link reaches a regeneration control start voltage, a controller controls switching elements and starts regeneration control. The regenerative current is accumulated in the capacitor through a diode. When a motor is in a power running state, the switching elements are turned on to apply the voltage at the power storage device to the DC link, and the charged power is utilized for motor acceleration. At that time, the regeneration control start voltage for the regeneration start detecting means is made higher, thereby preventing regeneration control from being activated due to application of the capacitor's voltage. Not only the regenerative current is effectively utilized by the power storage device, but also the regeneration control function can be utilized.
