Electro-mechanical drive with extended constant power speed range

Номер: US20120081059A1
Автор: Bernard Edwin Romig
Принадлежит: Deere and Co

Embodiments of the invention comprise a multi-input range box driven by multiple electric drives. Range shifting involves momentarily increasing the current through all but a given motor, to a level that will carry the entire load, comprising specified constant power. Simultaneously, torque of the given motor is reduced to zero. The given motor is then disconnected from supplying power, is synchronized to the input speed of the new speed range, and is then engaged for the new range. The above sequence is then repeated for each remaining motors, in turn. The motor current is re-equalized for all of the motors, after all the motors have been connected to provide power at the new range. Thus, there is no interruption in power flow during a range shift, and the motors are always used to deliver power, rather than to serve as a brake.

In a configuration in which an auxiliary power supply is connected to an intermediate link circuit of a main conversion unit, intermediate link voltage as input voltage of the auxiliary power supply is set at higher voltage depending on the main conversion unit as a main unit, and loss generated in a main circuit element of the auxiliary power supply increases; therefore, a problem has occurred that a cooling unit has to be increased in size. The main conversion unit recognizes a low-speed and stop state by monitoring a vehicle speed, and varies the intermediate link voltage corresponding to the vehicle speed; thereby, the loss generated in the main circuit element of the auxiliary power supply is reduced at the low-speed and stop state where cooling ability is decreased; as a result, small sizing and light weighting of the cooling unit is achieved.

Принадлежит: VOLVO CONSTRUCTION EQUIPMENT AB

A discharge system of a stored energy for a construction machine is provided, which includes the energy storage, an electric discharge device discharging energy stored in the energy storage, and an energy cooling portion increasing the heat dissipation capacity of the electric discharge device by cooling heat generated in the electric discharge device for a time when the energy stored in the energy storage is discharged to the electric discharge device. Since the heat generated in the electric discharge device is cooled by a cooling device while the energy stored in the energy storage is discharged to the electric discharge device, the heat dissipation capacity of the electric discharge device is increased to shorten the discharge time. Also, the operation period of the cooling device is controlled in proportion to the residual voltage of the energy storage, and thus the cooling efficiency is maximized.

Disclosed is a technique for compensating for an abnormal output of a resolver. More specifically, a central processing unit (CPU) sets a current motor position angle before compensation θ n,ORG as a current motor position angle θ n and obtains a motor position change Δθ n [rad] between a current sampling [n] and a previous sampling [n−1] and a motor position change Δθ n-1 [rad] between the previous sampling [n−1] and a more previous sampling [n−2]. Subsequently, a variable A is calculated based on the above angles. The CPU determines whether to perform the compensation by comparing the calculated variable A and a calibration variable K and calculates a current motor position angle for compensation θ n [rad]. Finally, the CPU compensates for the absence of motor rotor position information with the calculated current motor position angle for compensation θ n [rad].

When a stopped time during the period when charging or discharging of the electrical storage device is stopped is longer than the polarization elimination time, the controller regards a voltage value of the electrical storage device at the time of at least one of the start of the external charging or the completion of the external charging as an open circuit voltage of the electrical storage device. The controller calculates a state of charge corresponding to the voltage value as a state of charge that is used to calculate the full charge capacity by using a correlation between the open circuit voltage and the state of charge. The controller shortens the polarization elimination time as a rate of change increases. The rate of change indicates a ratio of a variation in the open circuit voltage to a variation in the state of charge.

A railroad network ( 10 ) having a track ( 12 ), a network energy supply ( 14 ) and a plurality of trains ( 16 ) that are connectable to the network energy supply ( 14 ) via means ( 20 ) for connecting the train ( 16 ) to the network energy supply ( 14 ) and each have an internal energy storage system ( 24 ) for receiving and storing energy originating from said train ( 16 ) or from trains ( 16 ) of the railroad network ( 10 ) and for supplying energy to said train ( 16 ) or to trains ( 16 ) of the railroad network ( 10 ). Each train ( 16 ) is able to switch from an operational state in which it is able to move along the system of rails ( 12 ) and an idle state in which it is unable to move along the system of rails ( 12 ) and vice versa. At least one of the trains ( 16 ) of the railroad network ( 10 ) is in the idle and energized state at the same time, its internal energy storage system ( 24 ) being connected to the network energy supply ( 14 ).

Electric Machine With Interchangeable Power Modules

Номер: US20220024324A1
Автор: Carlos Eduardo Nino Baron, Jonathan Matthew Baumann, Thomas Michael Sopko, Jr.
Принадлежит: Caterpillar Inc

An electric machine and method for powering the electric machine using interchangeable power modules that are configured to be interchangeably placed within power bays of the electric machine is disclosed. The electric machine includes an electrical module that is configured to receive power from one or more of the power modules placed in the power bays and transform, such as from DC to multi-phase alternating current (AC), and provide the power to one or more motors of the electric machine. The power modules may be of the same dimensions, same electrical interfaces, and/or same power output (e.g., type, magnitude) as each other to enable the interchangeability of the power modules. The power modules may be ones that generate power or ones that store energy. In some cases, the generating power modules may charge the energy storage power modules, while the energy storage power modules power the electric machine.
