摘要： An electric vehicle receives electric power, in a non-contact manner, from an electric power transmitting coil provided externally to the vehicle. The electric vehicle includes an electric power receiving unit that is disposed at a bottom of the vehicle and receives electric power from the electric power transmitting unit via electromagnetic field resonance; a camera that captures an image of the outside; and a display unit that displays an outside view from the vehicle that is captured by the camera. The electric power receiving unit is disposed at a position that is offset toward a peripheral face, on which the camera is disposed, with respect to the center of the bottom in the longitudinal direction of the vehicle.

摘要： A feeder is disposed along a guide rail that guides an electrically powered vehicle. The electrically powered vehicle has an electric power receiving unit that accommodates the feeder. Electric power is supplied from the feeder to the electrically powered vehicle through the electric power receiving unit on a non-contact basis. The distance between the guide rail and the feeder in a straight portion of the guide rail is different from the distance between the guide rail and the feeder in a curved portion of the guide rail.

摘要： The invention provides an automatic die changing system for a power press with at least one carrier for transporting dies to and from a selected location in the press. The carrier is supported on a set of wheels, which are driven by at least one AC induction motor. An adjustable frequency AC motor drive supplies an AC frequency and voltage to the AC induction motor to control the speed of the motor and therefore the speed of a horizontal movement of the carrier into or out of the press. The speed of the carrier may be rapidly increased by increasing the AC frequency supplied to the motor on the individual wheels. A proximity detector signals the motor drive to trip a dynamic braking resistor, which electronically changes the phase order of the motors to reverse the direction of motor rotation, to decelerate the carrier in order to locate the carrier in the proper position.

摘要： A railless vehicle for use underground is equipped with a three-phase asynchronous motor as the principal drive, and a power distributor with a plurality of power inputs as well as a magazine drum for the wind up or pay out of the power supply line. The drum 2 is connected to the distributor 8 through a hydrostatic drive 10. The control of hydrostatic drive 10 is a function of the slack of the free, not wound up portion of the supply line 3. This slack is detected by a contact lever 5, translated by a converter 14, and transmitted to a torque control 13, to vary the wind up or payout speed of the drum. Any undue horizontal and vertical deflections of the power supply line 3 are effective to switch off the principal drive 7.

摘要： An AC electric rolling stock controller includes a comparator that compares an intermediate link voltage VEFC generated at a smoothing capacitor with a setting value A, a comparator that compares the intermediate link voltage VEFC with a setting value B less than the setting value A, and a delayer that delays an output of the comparator in a case in which the output of the comparator is significant. It is determined that the initial charging of the smoothing capacitor is complete in a case in which at least one of an output of the comparator and an output of the delayer is significant.

摘要： A method for managing thermal energy of a vehicle having a battery and an electric propulsion system is provided. The system monitors a current battery temperature, after the vehicle is connected to an outside power source at a plug time, and determines an outside air temperature. The system predicts a cabin heating temperature for a subsequent drive cycle. The subsequent drive cycle occurs when the vehicle is no longer connected to the outside power source. If the predicted cabin heating temperature is greater than the outside air temperature, the system heats the battery to a thermal storage temperature that is greater than a target operating temperature of the battery. Therefore, thermal energy is stored within the battery, and may be transferred to heat the cabin.
