摘要： A motor driving apparatus includes a converter unit that converts alternating-current voltage supplied from an external power source into direct-current voltage, and a motor driving unit that receives direct-current power output from the converter unit and drives a motor. The motor driving apparatus stores direct-current power from the converter unit and regenerated power from the motor, and stores these power in a capacitor bank connected in series to a charging and discharging circuit. The capacitor bank connected in series to the charging and discharging circuit is integrated with a charging and discharging circuit optimum for a total capacitance of plural capacitors within the capacitor bank, thereby forming a module. One or more modules are provided corresponding to the capacitance required in the motor driving apparatus. Based on this configuration, the capability of the charging and discharging circuit and the capacitance of the capacitors are not limited by each other.

摘要： Provided to the motor controller is means which can alter a conversion ratio with which a current value detected by a current detector is converted into a unit (such as voltage) easily usable in motor current control. According to the maximum current value of the motor and the demagnetization limit current of the motor, an optimum conversion ratio is selected and switched over. By making it possible to select and preset a conversion ratio, a plurality of motors can be controlled by one motor controller. Therefore, restrictions imposed on the combination of the motor controller and the motor are lightened.

摘要： A motor drive system comprises first and second motor drive amplifiers (3a, 3b), connected to a motor drive power supply (6), which include first and second memories (32a, 32b) which store specifications of the amplifiers (3a, 3b) respectively. A memory (52) provided in a power supply unit control circuit (5) stores an overcurrent detection value for detecting an overcurrent according to the specifications of the respective motor drive amplifiers (3a, 3b). A microcontroller (51) reads the specifications from the first and second memories (32a, 32b), and integrates overcurrent detection values corresponding to the respective specifications. If a current sensor (7) detects a current exceeding a reference value calculated based on a set integrated value, an overcurrent detection circuit (54) outputs an overcurrent detection signal.

摘要： A motor driving apparatus 1 having a converter 2, which receives AC voltage and converts it to DC power, and an inverter 3, which receives the DC power and converts it to AC power, includes a charge/discharge control circuit 7 and a capacitor 8 connected in parallel to a link section between the converter 2 and the inverter 3, and energy stored in the capacitor C8 is charged and discharged at arbitrary timing by the charge/discharge control circuit 7. The invention thus provides a motor driving apparatus that supplies energy to a motor so that the peak of the input current from a power supply to the motor can also be suppressed when particularly large energy is needed during the second half period of motor acceleration.

摘要： A motor driving apparatus capable of drivingly controlling a plurality of inverter units (IV1-IV4) with a single motor driving command S from a motor control unit (1), to thereby control a large-capacity motor or the like. The motor control unit (1) sends out a single motor driving command (torque command) S. An intermediary unit (3) obtains motor driving commands SxA1 to SxA4 for the inverter units (IV1-IV4) by multiplying the motor driving command S by each of coefficients A1 to A4 set in advance. The inverter units (3) are fed with the motor driving commands SxA1 to SxA4 individually and drive a single motor (2). Since the motor (2) is driven by the total current supplied by the inverter units (IV1-IV4), the motor can generate a large torque. The motor control unit (1) only needs to generate a single motor driving command S, and hence only needs to operate a single processing part. Alternatively, the single motor (2) may be replaced by a plurality of motors, each associated with a respective one of the inverter units (IV1 to IV4). Also, the intermediary unit (3) may generate the individual motor driving commands in the form of parallel or serial data.

摘要： An inverter apparatus (10) is provided with first and second current detectors (4r, 4s) for detecting the current of two arbitrary phases (R, S) and further with first and second A/D converters (5r, 5s), and they are integrated into one unit. It furthermore stores, in a storage device (7), a compensation value for compensating for an unbalance between gains of the first current detector (4r) and the first A/D converter (5r), and gains of the second current (4s) detector and the second A/D converter (5s). By multiplying the detected current value of either one of the detected phases (R, S) by this compensation value, it equalizes the current feedback gains for both phases (R, S).
