摘要： PROBLEM TO BE SOLVED: To obtain a high-efficiency rotating electrical machine by suppressing the magnetic flux that flows in the direction of the axis of rotation.
SOLUTION: Permanent magnets 18 of a rotor have extended magnet portions 38, which extend outside both end portions of a rotor core 16 with regard to the direction of axis of rotation of the rotor. The magnetic flux 57, generated in the extended magnet portions 38, acts in such a way as to suppress the magnetic flux 56 which tends to enter the rotor core 16 and to leak outside, flowing through proximity portions 16a of the permanent magnets 18. Thus, the magnetic flux which flows through the proximity portions 16a of the permanent magnets 18 in the direction of axis of rotation can be reduced, and effective magnetic flux for the torque of the rotor can be increased.

摘要： PROBLEM TO BE SOLVED: To detect a load current from the on-voltage of an inverter main circuit element. SOLUTION: A voltage (the on-voltage), when a switching element Q or a diode D is in conduction state in the main circuit elements 18U-2, 18V-2, and 18W-2 of the lower side arm of the inverter 12, is detected by voltmeters 16U, 16V, and 16W. Since only the voltage during turning-on is extracted and detected, the voltage of about ±1.5V needs only to be detected and detection with high accuracy can be conducted.

摘要： PROBLEM TO BE SOLVED: To provide a motor drive system wherein torque ripples can be made smaller in rectangular wave control. SOLUTION: The motor driven system comprises an inverter which receives input from a high-voltage direct-current power supply, and converts it into a predetermined alternating current and outputs it; a motor which is driven by the output of the inverter; a low-voltage direct-current power supply connected with the neutral point of the motor; and a controller which controls the operation of the inverter. The controller controls the operation of the inverter with a predetermined rectangular wave and inserts breaks constituted of output inverted sections of predetermined width into the rectangular wave. At the same time, the controller varies the position of insertion of the breaks, according to the ratio of the voltage of the high-voltage direct-current power supply to that of the low-voltage direct-current power supply. A break, constituted of a section of a 0 voltage of a rectangular wave is chopped, when the inverter is driven with the rectangular wave. By having the position α and the width β of this break optimized, torque ripples are suppressed. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To reduce loss in an inverter system. SOLUTION: A DC power source is arranged between the neutral point of the star-connected coil of a motor M2 and the negative side DC line of a second inverter INV2. The neutral point of the star-connected coil of a motor M1 is connected to the positive side DC line of the second inverter.

摘要： PROBLEM TO BE SOLVED: To effectively suppress a maximum value of an amplitude of a motor driving current. SOLUTION: Two motor coils M1 and M2 are supplied with current from two inverters INV1 and INV2. The inputs of the inverters INV1 and INV2 are connected with a capacitor C, and a battery B is placed between the neutral points of the two motor coils M1 and M2. The motor coils M1 and M2 are installed on one rotor with a specified phase difference, and a motor is driven by current to both the motor coils M1 and M2. When the maximum amplitude of one of the motor coils is reached, the current is reduced by a specified amount and the reduced amount of the current is supplied to the other motor coil. Thus, the maximum value of amplitude of motor driving current can be suppressed without fluctuation in motor torque.

摘要： PROBLEM TO BE SOLVED: To control an inverter input voltage over a wide range and to efficiently drive a motor. SOLUTION: A DC power supply 40 is connected between neutrals of two three-phase coils 24 and 26 of a 2Y motor 22, which are wound on a same stator and to which three-phase AC powers are respectively supplied with a phase difference, corresponding to a winding shift angle between each other from two inverter circuits 30 and 32, which have a positive pole bus-bar 34 and a negative pole bus-bar 36 in common, and a capacitor 38 is connected between the positive pole bus-bar 34 and the negative pole bus-bar 36. By the switching control of the inverter circuits 30 and 32, the potential difference between the neutrals of the three-phase coils 24 and 26 is made to be smaller or larger than the voltage of the DC power supply 40 to charge or discharge the capacitor 38. Wuth such a constitution, an inverter input voltage can be regulated over a wide range.

摘要： PROBLEM TO BE SOLVED: To prevent an electric motor from outputting unexpected torque at the start and to start quickly. SOLUTION: When a DC power supply 32 is connected by switching on a relay 34 at a start, transistors at the negative pole bus 28 of an inverter circuit 24 are switched on to form a short-circuit with regard to the phase of the minimum phase current of each of u, v, w phase currents. As for the other phases, a capacitor 30 is initially charged by repeating the process of forming a charging circuit by switching off the transistors at the negative pole bus 28 of the inverter circuit 24. Because the current increasing speed in the short- circuit is larger than that in the charging circuit, the current-increasing speed of each phase can be equalized by repeating the above process. Consequently, because the equalized current of each phase can be caused to flow, the output of the unexpected torque from a motor 22 can be prevented when the capacitor 30 is initially charged.

摘要： PROBLEM TO BE SOLVED: To provide a circuit for connecting two DC power supplies of different voltages, such as an electric system for driving and an electric system for a control circuit of an electric vehicle, and for transmitting power between these power supplies. SOLUTION: When there are an inverter for driving a three-phase motor and two DC power supplies connected to the inverter, each of the DC power supplies is divided into two or more parts and a neutral point Q1 of a three- phase motor 30, and a mid point P6 between low voltage batteries 61, 62 which are a second DC power supply are connected. Moreover, the positive pole side and the negative pole side of the low voltage batteries are connected to a division point P5 of another DC power supplies (fuel batteries) 21, 22 through diodes DmU and DmL respectively. By controlling the current of each phase of the three-phase motor through the inverter, the voltage at the neutral point of the three-phase motor 30 can be controlled. The low voltage batteries are charged by this voltage. The three-phase motor 30 can be driven also by the low voltage batteries 61, 62 through diodes DaU and DaL.

摘要： PROBLEM TO BE SOLVED: To make it possible to control driving torque at high speed while reducing vibrations of a power unit in a vehicle with a motor in the power unit. SOLUTION: When a torque command value is applied to an actual vehicle 41, a motor is rotated according to the torque command value, and the revolutions are detected by a revolution detector 43. At this time, estimation driving torque is calculated from the revolutions using a target reverse model 44. The estimation driving torque and the torque command are compared by using a comparator 45 to obtain a difference as disturbance estimation torque. Then, the disturbance estimation torque passed from a filter 46 is multiplied by a gain (K) to generate control torque. By using control torque, required torque is increased or decreased to obtain a torque command value.
