摘要： PROBLEM TO BE SOLVED: To increase energy density, by specifying the number of the poles of a permanent magnet, and specifying the number of slots which permits a three-phase armature winding formed at a stator iron core to be disposed for concentrated winding. SOLUTION: Number of the poles of a permanent magnet 2 in a rotor iron core 3 is formed of 14 pieces and the number of slots is formed of 12 pieces, which permits three-phase armature windings U, V, W, U', V', W' formed at a stator iron core 1 to be disposed for concentrated winding. Therefore, the energy density Edc is improved by forming multi-polarization of the 14 poles, thus enabling to attain size reduction of 10 to 15% in a motor volume compared to conventional embodiments. Quantity of magnet used can also be reduced by 30 to 40% from a product with identical demagnetization strength compared to the conventional embodiment, thus enabling to attain cost reduction. The current capacity of a deriving amplifier is not changed by forming multi- polarization, therefore, it is possible to use a power semiconductor element equivalent to that of a conventional motor. It is also possible to attain the equivalent performance to that of the conventional motor in cogging torque.

摘要： PROBLEM TO BE SOLVED: To solve the problems of a power supply unit in which a plurality of batteries such as a fuel battery and a secondary battery are connected to a load in parallel is expensive, because the fuel battery has the upper limit of an output and needs the assistance of the secondary battery, and although the secondary battery needs to be charged and must use a DC-DC converter, which meets the maximum output of the battery, and cannot improve power generation efficiency because of the internal loss of the DC-DC converter. SOLUTION: The plurality of batteries having different principles of power generation and characteristics are connected into the load parallel, a changeover switch is attached on a battery output side, the battery supplying the largest power to the load is directly connected to the load, and the other assistance batteries are connected to the load through the DC-DC converter. The battery supplying the largest power to the load is directly connected to the load, thereby preventing the internal loss caused by the DC-DC converter fro being generated, and minimizing the capacity of the DC-DC converter connected to the assistance batteries. The power supply unit which is highly efficient and inexpensive can be thus provided.

摘要： PURPOSE:To detect a shaft-speed signal stably without the effect of noises by operating the difference between the angular speed of an exciting signal for a resolver and the angular speed of the secondary sine wave signal which is generated in the secondary output winding. CONSTITUTION:A waveform shaping circuit 1 outputs a gate signal 200 at a logic 1 when the secondary exciting signal of a resolver is positive and a gate signal 200 at a logic 0 when the signal is negative to a gate circuit 3. Pulses to be counted 400 are inputted into a counter circuit 6 through the circuit 3 when the signal 200 has the logic 1 based on a clock pulse 300 from a reference clock circuit 2. The circuit 3 outputs a falling differentiated pulse signal 500 of the signal 200 to first and second delay circuits 4 and 5 and a latch circuit 7. The circuit 6 counts the pulses 400 at the input interval of a pulse signal 600 from the circuit 4. The counted value of the pulses 400 is latched 7 at the timing of the signal 500. The value corresponding to the period of the resolver exciting signal is subtracted from the counted value which is proportional to the period of a resolver secondary-sine-wave signal (a) in an operating circuit 9. Thus the value which is proportional to the shaft speed is obtained. The value is converted in an A/D converter 10, and a resolver speed signal (d) is outputted 10.

摘要： PURPOSE:To perform an evaluation for a driving system characteristic without using an actual system by providing a 1st and a 2nd electric motors and a 1st generator. CONSTITUTION:An energy conversion efficiency is a ratio of an input mechanical power driving a 1st motor 2 to an output mechanical power outputted from a 2nd motor 4. A vehicle driving characteristic is defined by a relation of the number of the rotation and the torque for a shaft outputted from the motor 4 and a relation of a driving torque to a velocity of a vehicle, by which a speed change characteristic an be evaluated. A regeneration characteristic is the ratio of the mechanical power inputted from a shaft of the motor 4 to a heat power generated from a 1st treating device 5 for the regeneration energy, by which the regeneration efficiency and a braking operation characteristic can be evaluated. Then, the heat generation characteristics of a rotary machine are the ratio of operating efficiencies and the input powers for a 1st generator 3 and the motor 4 respectively to the output power, by which a cooling capacity required for the actual machinery can be evaluated. The evaluation for the driving system characteristic can be thus evaluated without using the actual system.

摘要： PURPOSE:To simplify the constitution, miniaturization and low cost by constituting the titled rotary encoder with an INC encoder having a sufficient split number for the sinusoidal wave drive and an ABS encoder generating a signal having an enough split number to drive various servo motors without any reaction torque. CONSTITUTION:The totary encoder consists of the incremental (INC) encoder 5 having an enough split number for sinusoidal wave drive and an absolute (ABS) encoder generating a signal having an enough split number to drive various servo motors without any reaction torque. Further, the ABS encoder consists of a rotary disk 10 processed easily and six position detectors 9, and the detectors 9 are arranged at an electric angle in reponse to number of poles of a motor while the mutual interval of the detectors 9 is parted sufficiently. Thus, a drive signal is generated from the ABS encoder at the initial start of a servo motor and a position signal from the INC encoder is used as a motor drive signal at the generation of a zero signal of the INC encoder, then miniaturization is attained.
