    Abstract: A vehicle including an AC rotating electric machine, an inverter, and an electronic control unit is provided. When an overcurrent abnormality occurs, i.e., phase current of a motor-generator exceeds a permissible value, in a high rotational speed region, the electronic control unit performs control (upshift control) for shifting up an automatic transmission provided between the motor-generator and driving wheels, or control (neutral control) for bringing the transmission into a released state, so as to reduce the rotational speed of the motor-generator. If phase current is detected even when an all-gate turn-off command is generated to the inverter while the rotational speed of the motor-generator is reduced to be within a low rotational speed region under the upshift control or neutral control, the electronic control unit determines that a short-circuit fault occurs in the inverter.

  • Publication number: 20130257047
    Abstract: This is a system of kinetic power generating stations that produce renewable and clean energy from moving railcars. The amount of green energy produced will be dependent on inertia, weight, momentum, and speed of train. The system has a second purpose of braking and reducing the trains speed by using the actuator pads necessary for harnessing the kinetic energy formed by the train. This will reduce the cost of fuel. By utilizing a plurality of opposing stations along the railway, braking of the train can be done more safely. Using computers and sensors, the actuator pads can control how much “drag” is necessary to slow the train down while collecting the energy formed by the moving train. The generators are spun by passing actuators attached to railcars at specific intervals. Opposing braking mechanisms will increase drag pressure by being engaged.

  • Patent number: 5915306
    Abstract: A mounting assembly secures a generator and facilitates attachment to a railroad railcar on the end of the railcar axle. The generator produces electricity from the axle of a railroad railcar while it is traveling on a railroad track. A generator is mounted with a generator bracket and a backing plate to an existing bearing adapter on the railcar. A drive hub engages axle bolts on the railcar axle. As the railcar axle turns, the drive hub turns and with the drive hub connected to a generator the generator subsequently rotates to supply electricity to the railcar. Different types of generators can be attached with the mounting assembly to the railcar. The mounting assembly allows generators to be mounted without modification to the existing railcar structure.

  • Patent number: 5775229
    Abstract: Invention relates to an on-board electrical generator system that may be retrofitted to existing railroad vehicles, such as freight cars, box cars, and the like, where rotation of the vehicle's axle powers the system. A preferred use thereof is to charge the battery for the electrically controlled brakes on the vehicle. Such vehicles typically include a chassis, having plural axles mounted thereon, and a journal box or adaptor block having a projection generally aligned parallel with the axles. Each axle contains a pair of wheels, which are inwardly mounted from the respective axle ends and rotatable with the axle. The generator includes a rotor fixed for rotative movement relative to a stationary stator, whereby such relative movement causes electric currents to be generated in the stator containing the generator in a non-rotatable housing.

  • Patent number: 5629567
    Abstract: A speed control system for an AC electric locomotive of the type having a plurality of wheel-axle sets with each wheel-axle set being coupled to an independently controllable AC electric traction motor and each motor having a corresponding speed sensor, each speed sensor providing a pair of signals which are resolvable to determine the speed and direction of rotation of the associated motor rotor, wherein the control system is arranged for maintaining torque control during failure of one of the signals from an associated speed sensor. The system detects the presence of each of the pair of signals from each speed sensor and responds to detection of only one of the pair of signals from one of the speed sensors for setting motor speed in response to the detected one of the signals. Direction is then determined by using signals from another of the speed sensors.

  • Patent number: 5392741
    Abstract: A water cooling system for a locomotive engine that enables the engine to operate at a maximum power level that generates a maximum permissible engine cooling water temperature corresponding to a particular ambient air temperature. The water cooling system can be either an open-loop or a closed-loop controlled system. In the open-loop control system, an ambient air temperature sensor measures the ambient air temperature. When the ambient air temperature exceeds a predetermined value, a signal from the temperature sensor to a signal processor automatically causes the engine power to derate in accordance with the temperature such that the heat generated by the engine maintains the water temperature of the cooling water constant. An ambient pressure sensor senses ambient pressure such that a correction factor is supplied to correct for cooling losses at higher altitude.

  • Patent number: 4697091
    Abstract: A device for detecting when a driven apparatus has frozen and/or its prime mover coupling mechanism is slipping. The rotational speed of a voltage generating alternator which is also driven by the prime mover is detected and a corresponding speed signal is compared to a reference speed signal. The reference speed signal corresponds to a speed slightly lower than the idling speed of the prime mover. When the detected speed signal is lower than the reference speed signal, slippage in the prime mover coupling mechanism is presumed and a slippage signal is provided. The slippage signal is used to control the coupling mechanism to disengage the apparatus from the prime mover to prevent damage from occurring.
