摘要： An axial gap rotating electrical machine is provided with permanent magnets and cores in a rotor. The permanent magnets are oriented such that magnetization surfaces face in the circumferential direction of the rotor. The cores are arranged alternately with the permanent magnets in the circumferential direction of the rotor. The amount of magnetic flux on the outside in the radial direction of the rotor is made greater than the amount of magnetic flux on the inside in the radial direction of the rotor. As a result, the magnetic flux density at the rotor cores can be made substantially constant in the radial direction of the rotor and torque output with respect to the size of the permanent magnets is improved by preventing magnetic saturation of the cores.

摘要： An electric drive control device is provided with an electric machine having an asymmetrical salient pole, a current detecting portion, a phase converting device that converts the detected current into an axis current, and a current controlling device which generates a voltage command value based on the axis current and a current command value of the axis current. The current controlling device generates the voltage command value in response to the detected current and an offset angle of the center of a magnetic flux density distribution occurring at the salient pole, with respect to the center of an opening angle of the salient pole. In this case, the current controlling device generates a voltage command value corresponding to the detected current and the offset angle so the electrical characteristics are the same as when an electric machine having a symmetrical salient pole is used.

摘要： An axial gap electric rotary machine includes a rotor and a stator which face each other with an axial gap therebetween. The rotor includes permanent magnets which are arranged with their magnetic poles spaced around the circumference of the rotor, with the magnetic poles of adjacent permanent magnets being opposite each other. The permanent magnets and rotor cores are alternately arranged around the circumference of the rotor. Consequently, north poles and south poles are alternately formed at a surface of the rotor facing the stator, and reluctance of a magnetic path which passes through a permanent magnet is larger than reluctance of a magnetic path which does not pass through the permanent magnet, whereby the functions of a reluctance type rotary machine and a permanent magnet synchronous machine are combined in a compact structure.

摘要： A control apparatus that controls a driving apparatus configured with a stator. A variable magnetic flux type rotating electrical machine has a first and second rotor, circumferential direction relative positions of which can be adjusted. A relative position adjustment mechanism adjusts the relative positions of the two rotors. A control command determination unit that determines, on the basis of a required torque and a rotation speed, an inter-rotor phase command indicating the relative positions for minimizing a system loss including at least an electrical loss, which includes a copper loss and an iron loss of the rotating electrical machine, and a mechanical loss of the relative position adjustment mechanism. A current command drives the rotating electrical machine. A control unit controls the rotating electrical machine on the basis of the current command and controls the relative position adjustment mechanism on the basis of the inter-rotor phase command.

摘要： A control device for a driving apparatus. The control device is configured with a device that controls the rotary electric machine via the inverter, a device that determines whether a disconnect condition of the main power supply is satisfied, and a device that obtains an estimated field amount that is an estimated value of the field flux supplied from the rotor to the stator. The control device is also configured with a device calculates an induced voltage that is induced in the coil, and a device that determines whether an overvoltage state in which the induced voltage exceeds a voltage resistance of the inverter exists. If it is determined that an overvoltage state exists when the disconnect condition is satisfied, connection with a main power supply is maintained until the overvoltage state is eliminated. The rotary electric machine is controlled by weakening the field flux to the coil.

摘要： An axial gap electric rotary machine includes a rotor and a stator that face each other across an axial gap. The rotor is provided with salient poles and permanent magnets that are positioned separately around the circumference of the rotor. Accordingly, north poles and south poles are alternately formed on a surface of the rotor that faces the stator. The magnetic resistance of a magnetic path that passes through the permanent magnets is larger than the magnetic resistance of a magnetic path that does not pass through the permanent magnets. Accordingly, the axial gap electric rotary machine is able to function as a reluctance motor and as a permanent magnet synchronous motor using a single set of facing surfaces of the rotor and the stator, respectively.
