摘要： In an industrial machine using a flywheel, in order to prevent increase in size of a driving motor, etc. and very freely control velocity of a load, an output shaft of a reduction gear set is connected to a load driving shaft, an input-shaft-sided gear of the reduction gear set is driven by a first motor, a differential mechanism is connected to the flywheel, the differential mechanism is configured such that the output shaft of the reduction gear set is connected to a carrier, rotational force inputted from the sun gear is transmitted to the flywheel and stored as energy while the stored energy is discharged to the sun gear and the carrier. Further, the sun gear of the differential mechanism is driven by a second motor, energy is stored by accelerating the flywheel using the second motor according to the rotational angle position of the load driving shaft, and then the load driving shaft is driven while compensating insufficient torque of the first motor by discharging the stored energy.

摘要： A highly efficient and reliable motor control system and motor control method are provided. The motor control system includes a motor having a plurality of sets of armature windings, a plurality of inverters which drive the plurality of sets of armature windings, and a plurality of control devices which control the inverters individually. In the motor control system: while a motor torque command is in a smallest-magnitude range, a first inverter is operated to energize a first set of armature windings; when the motor torque command increases into a next larger-magnitude range, the first and a second inverter are operated to energize the first and a second set of armature windings; when the motor torque command increases into a still next larger-magnitude range, the first, the second, and a third inverter are operated to energize the first, the second, and a third set of armature windings; and when the motor torque command increases into a largest-magnitude range, all inverters are operated to energize all sets of armature windings. Thus, the number of inverters driven and/or the number of sets of armature windings energized are sequentially changed according to the torque command.

摘要： A motor drive control device including a power supply converter that is connected to an alternating-current power supply, a voltage detector that detects a direct-current voltage of the power supply converter, an inverter that is connected to a motor, and an energy storage device that is connected to a direct-current bus that connects the power supply converter and the inverter. The motor drive control device includes: a power-running operation start voltage setting section that sets a power-running operation start voltage of the power supply converter; a power-running operation start control section that causes the power supply converter to start a power-running operation when the direct-current voltage of the power supply converter has reached the power-running operation start voltage set by the power-running operation start voltage setting section; a power-running operation stop voltage setting section that sets a power-running operation stop voltage of the power supply converter; and a power-running operation stop control section that causes the power supply converter to stop the power-running operation when the direct-current voltage of the power supply converter has reached the power-running operation stop voltage set by the power-running operation stop voltage setting section.
