摘要： In a vacuum cleaner comprising an electric blower and a speed control unit to operate the electric blower at a variable speed, a plurality of kinds of operation control rules of the electric blower are previously stored in the speed control unit, a load current value of the electric blower is continuously detected during the cleaning and the type of the surface to be cleaned is estimated from the load current value. Thereafter, the operation control rule suitable for the estimated cleaning surface is selected from the operation control rules stored in the speed control unit and the electric blower is driven on the basis of the selected operation control rule.

摘要： First magnetic angular sensor outputs a sine-wave output and a cosine-wave output corresponding to positions of rotation of a rotary drum being fitted in a rotating drive shaft. Second magnetic angular sensor outputs a sine-wave output and a cosine-wave output corresponding to positions of rotation of another rotary drum being fitted on the rotating drive shaft. In case of the other output of the sine-wave output or the cosine-wave output of the first or the second magnetic angular sensor is varied while one output of the sine-wave output or the cosine-wave output in the first or the second magnetic angular sensor is not varied, the one output cosine-wave output or the sine-wave output of the first or the second magnetic angular sensor is determined to be a fault and an abnormality signal is delivered therefrom. The electric driven power steering apparatus having an assist torque means employed the magnetic angular sensor structure can be prevented in advance from the accident and high reliability thereor can be obtained.

摘要： Disclosed is a speed controlling method and apparatus in which a suitable current or voltage command is given to a moving body on the basis of the relation between a speed detection signal obtained by detecting the speed of the moving body and an externally supplied speed command signal. The speed of the moving body is controlled in a manner so that the speed of the moving body is successively detected, a speed error which is a difference between a speed command value and a speed detection value is calculated whenever the speed of the moving body is detected, and the speed of the moving body is successively controlled on the basis of a driving signal obtained by an arithmetic operation on the basis of the speed error and a set control gain, and that, on the other hand, a present speed error quantity is calculated on the basis of speed errors obtained whenever the detection of the speed of the moving body have been carried out predetermined number of times, the speed error quantity obtained presently is compared with and the speed error quantity obtained last, and the set gain is corrected or updated in accordance with the result of comparison of the present and last speed error quantities to thereby minimize the speed error quantity.

摘要： A large number of teeth are formed on the outer circumference of a rotor. A stator is disposed around the rotor. The stator has multiple magnetic poles whose number is n times the number of phases. Each pole has formed on its surface a plurality of teeth at a pitch equal to the rotor tooth pitch. The teeth mounted on the adjacent magnetic poles are selected to deviate in pitch one-half or thereabout from the rotor teeth and the adjacent poles are to be opposite phases from each other.

摘要： A method and an apparatus for controlling the operation of the synchronous motor are disclosed in which the synchronous motor is started with a starting power supply and operated with a steadying power supply. The starting power supply is adapted to alternately repeat acceleration and deceleration of the synchronous motor in the neighborhood of the frequency thereby to bring the synchronous motor into the point where the synchronous motor is in synchronism with the steadying power supply. The starting power supply comprises a current control circuit and a phase angle control circuit, which circuits control the motor current in such a manner as to prevent the voltage drop due to the synchronous reactance of the motor from exceeding the induced voltage of the motor, while at the same time controlling the power factor angle to be in the range from a lead 90.degree. to the angle corresponding to a maximum output point produced by said motor current.
