摘要： A fitness equipment energy regenerating and saving system is provided. The system includes a bidirectional power converter, a bidirectional power drive, a generator, and an energy managing circuit. The energy managing circuit activates the bidirectional power converter so as to enable the bidirectional power drive to feedback the power generated by the generator to an electrical grid when the generator is operated in a generator mode. The energy managing circuit sets the bidirectional power converter to a current-regulating mode so as to enable the bidirectional power drive to obtain the power required for driving from the electrical grid when the generator is operated in a motor mode.

The excitation and non-excitation intervals are symmetrical with centers that respectively correspond to the π/2 and π phase points of the induced voltage waveform. The regeneration controller includes a regeneration interval setting unit that sets regeneration and non-regeneration intervals such that power is regenerated from the electromagnetic coil during the regeneration interval but is not regenerated during the non-regeneration interval.

摘要： Regenerated power from actuation loads of an aircraft may be returned to the distribution bus of the aircraft. In the past, actuators were either hydrostatic or pneumatic. With the furtherance of more electric architecture (MEA) aircraft, there has been an increase in electrical actuation modes. The power or current exchange between electrical buses and the electromechanical and electro-hydrostatic flight control actuators is bidirectional, resulting in a need to accommodate regenerative power. Conventional methods may use shunt regulation to dissipate regenerated power. These methods require additional cooling to reject the heat generated. This regenerated power is wasted as dissipated heat. The present invention, on the other hand, may dump the regenerated power back to a power sink, such as into ancillary electrical loads or to the starter/generator as mechanical (kinetic) energy. In the present invention, the energy may not be wasted nor may it generate excessive heat that needs to be dissipated.

摘要： A motor control apparatus can protect circuit elements in an appropriate manner while preventing an incorrect abnormality determination when a motor is in regeneration operation, etc. The apparatus includes a target current calculation section (51), a drive control section (52) that generates a drive signal based on a current deviation ΔI between a target current (IMT) and a detected current (IMS), an abnormality determination section (53) that generates an abnormality determination signal based on the target current (IMT) and the detected current (IMS), and a regeneration operation determination section (59) that determines whether the motor (4) is in a regeneration operation state. When it is determined that the motor (4) is in a regeneration operation, a determination threshold of the abnormality determination section (53) is set to a value larger than a determination threshold during power running operation.

摘要： A motor drive apparatus is provided in an injection molding machine in order to supply electrical energy to a motor. The motor drive apparatus includes an electricity accumulation unit for accumulating electrical energy; and an electricity accumulation circuit for accumulating in the electricity accumulation unit electrical energy regenerated from the motor during a deceleration period of the motor and for supplying the electrical energy accumulated in the electricity accumulation unit to the motor during an acceleration period of the motor. By virtue of the above-described structure, when a heavy member such as a screw of an injection apparatus or a movable platen of a mold clamping apparatus is moved at high speed in each molding cycle, at the beginning of movement or during an acceleration period of the motor, the electricity accumulation circuit adds the electrical energy accumulated in the accumulation unit to electrical energy that is supplied from a power source to the motor, and during a deceleration period of the motor, electrical energy regenerated from the motor is accumulated in the accumulation unit.
