摘要： A drive system includes a drive device including an electric power generator; a fuel cell; a secondary battery; a fuel cell step-up converter including a diode; a relay connected to wiring between the fuel cell step-up converter and the drive device; a secondary battery step-up converter connected; a fuel cell voltage sensor; a secondary battery voltage sensor; and a controller. The controller stops the secondary battery step-up converter when a short-circuit fault of the diode is detected, disconnects the relay when a voltage of the fuel cell is higher than a voltage of the secondary battery after stopping the secondary battery step-up converter, and when the voltage of the secondary battery is higher than or equal to the voltage of the fuel cell, executes a voltage control process which increases the voltage of the fuel cell relative to the voltage of the secondary battery, and disconnects the relay.

摘要： An electric power assembly for a vehicle is disclosed. An electric motor includes a stator and a rotor being rotatable about a pivot axis relative to the stator. An inverter is coupled to the electric motor and includes a power switching device that outputs an electrical signal from the inverter at a first frequency and having interference at a second frequency. The second frequency is a byproduct of the electrical signal creating the first frequency. The stator is electrically connected to the inverter to receive the first frequency such that the stator produces a first magnetic field. A frequency filter is attached to the rotor and directs the portion of the electrical signal having the second frequency to the rotor such that the rotor produces a second magnetic field that interacts with the first magnetic field to rotate the rotor about the pivot axis relative to the stator.

摘要： A rotor for an LSIPM comprises a plurality of permanent magnets defining a number of poles (“P”) of the LSIPM, and a plurality of rotor bars spaced about the rotor defining a rotor bar area (“BA”). The rotor bars are formed of a conductive material having an associated conductivity (“σRB”). End members are disposed on axial opposite ends of the rotor core. The end members are in electrical contact with the rotor bars. The end members are formed from a material having an associated conductivity (“σEM”). Each end ring member has a minimum geometric cross sectional area (“ERA”) and outer diameter that generally corresponds to the rotor core outer diameter. The ERA is greater than 0.5 times the rotor bar area per the number of poles (BA/P) times a ratio of the rotor bar material conductivity to the end member material conductivity (σRB/σEM).

摘要： A starting method and system for a motor where the motor may be started as an induction motor by applying a magnetizing current to build flux through the stator, with the field current set at the maximum permissible exciter stator current (i.e., the current that will cause rated no-load current in the main field at the transition speed). The motor stator currents will be maintained at a value that allows the motor to generate sufficient breakaway torque to overcome any stiction. At a specific transition speed or after a period of time, the drive will initiate a transition from induction motor control to synchronous motor control by removing the initial magnetizing current, and a field current is then applied to the motor through the DC exciter. Once this transition is completed, the drive may ramp up to the desired speed demand.
