摘要： The conventional linear drive apparatus has the problem that in constructing a linear motor of a multiphase structure by connecting a plurality of armature units, the length of the armature becomes longer in proportion to the number of the phases, thus limiting the locations where the apparatus can be installed. The problem is solved by a linear drive apparatus comprising a plurality of armature units 3 formed by a magnetic material on which a conductor coil 4 is disposed, and an armature comprising an arrangement of the armature units 3. The armature units 3 comprise a plurality of opposing portions having opposing magnetic pole teeth. The magnetic pole teeth of adjacent opposing portions are arranged in an interdigitated manner. A secondary member 6 is disposed between magnetic pole teeth of the opposing portions. The armature units 3 comprise the coil 4 arranged on opposite sides thereof in an alternating manner.

摘要： An control system for an induction motor driven by an AC output of variable frequency and voltage produced from an inverter which converts DC power obtained by a converter through conversion of AC power having constant voltage and constant frequency. The system comprises means for estimating the power factor of the induction motor from an input current to the inverter, means for controlling the voltage of the AC output from the inverter when the estimated power factor is outside a predetermined range, and means for restricting the control of the AC output voltage to prevent the ratio between the AC output voltage and the AC output frequency from exceeding a predetermined range.

摘要： In a control method and device for an AC motor, when transforming output power of a converter to AC power by an inverter and controlling the AC motor with the AC power, a source current value is determined from the value of an electric variable in the input or output side of the inverter, and the converter is controlled in accordance with the source current value. This makes the source current free from an influence of ripple components. Accordingly, even when the load of the AC motor is fluctuated abruptly, the required AC power can be applied to the converter so as to follow such fluctuations.

摘要： In spatial vector control of a pulse width modulation (PWM) inverter adapted for variable speed drive of an induction motor, a difference vector between magnetic flux vectors occurring during adjacent sampling periods is generated by synthesizing a zero vector and voltage vectors in such a manner that a resultant voltage vector always includes as a component a minimum unit of a zero vector or a voltage vector, whereby even when the angular speed of rotation of the magnetic flux changes, the switching frequency of the PWM inverter is prevented from decreasing and the current ripple is reduced.

摘要： An inverter control apparatus includes an instruction calculator which receives a speed instruction and a particular component of a current of a motor to obtain an output frequency instruction and output voltage instructions of an inverter and a current estimator to estimate, according to a reference phase obtained by integrating a current detection value of one phase of an ac motor and an output frequency instruction thereof, currents of other phases of the ac motor. The current estimator includes a uvw/dq converter which converts a fixed coordinate system into a rotating coordinate system, a dq/uvw converter which is connected to the uvw/dq converter and which converts the rotating coordinate system into the fixed coordinate system, and a closed loop to input an output from the dq/uvw converter to the uvw/dq converter. This system can therefore estimate currents of other phases according to the motor current of one phase.
