摘要： PROBLEM TO BE SOLVED: To provide a controller for a permanent magnet motor serving as a starter of an engine and a power generator requiring only a small loading space in a vehicle and dispensing with a large-scale starter relay. SOLUTION: A brushless motor 9 is driven through an inverter circuit 12 by connecting a shaft of a brushless motor (permanent magnet motor) 9 with an output shaft of the engine and setting a chopper circuit 24 in a non-operation state or by operating it as a booster chopper, when operating the motor 9 as the starter of the engine. When the brushless motor 9 is operated as the power generator, if a power generation voltage of the brushless motor 9 is higher than a voltage of a battery 10, the inverter circuit 12 is set in the non- operation state, and the chopper circuit 24 is operated as a pressure reducing chopper to charge the battery 10. If a power generation voltage of the brushless motor 9 is lower tan a voltage of the battery 10, a transistor 14U or 14W on a negative side of the inverter circuit 12 is turned on and off while a transistor 25 of the chopper circuit 24 is turned on to operate the inverter circuit 12 as the booster chopper so as to charge the battery 10.

摘要： PROBLEM TO BE SOLVED: To provide a motor which has a simple construction and is easily assembled and with which a load can be protected from contamination caused by the scattering of lubricant. SOLUTION: Inclined trenches 18a which are inclined in a direction opposite to the rotating direction of a rotor 13 are formed in the inner circumferential part of a rotor magnet 18. If the rotor 13 rotates, air flows are produced along the inclined trenches 18a upward from the lower part of the inner circumferential part of a rotor yoke 17. The air flows are made to flow through bearings 12 and 12 in a direction opposite to the side where a polygon mirror 19 is attached.

摘要： PURPOSE:To reduce frictional force acting on a movable section and to improve effective thrust by providing an auxiliary power source which applies AC voltage or pulsating DC voltage across electrodes arranged to form a capacitor. CONSTITUTION:With each electrode 13a to 13e and 14a to 14e each capacitor is formed. Each fixed contact A is connected to corresponding electrodes 13a to 13e respectively, while each common contact C is connected to a line 17 in common. Between each fixed contact B of changeover switches 19a to 19e and electrodes 14a to 14e AC power sources 20a to 20e, which are auxiliary power sources, are respectively connected. In the condition where AC voltage or pulsating DC voltage is applied across electrodes 13a to 13e and 14a to 14e from the auxiliary power sources 20a to 20e, periodically fluctuating attractive forces are generated between electrodes 13a to 13e and 14a to 14e, so that the electrodes 13a to 13e and 14a to 14e will be oscillated.

摘要： PURPOSE:To obtain a high output and a high torque by constituting a capacitor group from respective pluralities of first and second electrodes and by selectively charging the part between said electrodes with electricity through a switching circuit to cause an electrostatic force to act on both electrodes. CONSTITUTION:In the sun cylinder 1 of a first tubular body fixed at a stationary part, a bearing 2 is fastened to the inner surface side of a flat bottomed base wall part 1a. On the inner peripheral face of said cylinder 1, there are arranged e.g., 36 first electrodes 101-136, and an insulating film 3 of high dielectric constant is attached to said inner peripheral face in the manner of covering said electrodes. Then, the planet cylinder 4 of a second tubular body is smaller in diameter than the sun cylinder 1 and an output shaft 5 is integrally formed in the base wall part 4a. Further, 30 second electrodes 201-230 are arranged on the inner peripheral face of said planet cylinder 4 to form a capacitor group with said insulating film 3 held between. Thus, the part between said electrodes is selectively charged with electricity by the change-over switch 6a of a switching circuit 6 so that an electrostatic force acts on both electrodes and a torque is taken one from the output shaft 5.

摘要： PURPOSE:To supplement a deficit of a motor torque without deteriorating the performance of a driving motor for a compressor by matching a compressor load condition with a rotating angle position of a motor rotor. CONSTITUTION:The system can be operated in such a way that a motor torque exceeds a compressor load torque and both are overlapped together at any time in all areas during a rotation of a rotor 27. By selecting a more delicate arrangement between the location of a piston 19 and the locations of a stator 23 and the rotor 27 within the 270 deg. segment of the motor torque, a compressor 13 can be driven with a smaller outer power. Accordingly, the motor torque satisfies the load torque sufficiently, and a deficit of a motor torque can be supplemented.

摘要： PROBLEM TO BE SOLVED: To provide a driver of water pump having a high degree of freedom in the installing position in which stabilized operation is ensured even under a noisy environment. SOLUTION: A position detecting circuit 19 compares the terminal voltages Vu-Vw of a brushless motor 14 disposed in a water pump for circulating cooling water with a reference voltage Vc to detect positional signals Pu-Pw and delivers drive signals Dup-Dwn to an inverter circuit 18 based on the positional signals Pu-Pw. Furthermore, a rotational speed is detected based on the positional signals Pu-Pw and the duty ratio of a control signal Dch for a step down chopper circuit 17 and a transistor 24 is controlled based on the detected rotational speed and a command rotational speed. Consequently, the DC voltage Vdc between DC buses 26 and 27 is varied and PAM control is performed and the rotational speed of the brushless motor 14, and thereby the flow rate of cooling water, is controlled.
