摘要： Provided is a drive device for an alternating current motor which performs vector control on sensorless driving of the alternating current motor in an extremely low speed region without applying a harmonic voltage intentionally while maintaining an ideal PWM waveform. A current and a current change rate of the alternating current motor are detected, and a magnetic flux position inside of the alternating current motor is estimated and calculated in consideration of an output voltage of an inverter which causes this current change. The current change rate is generated on the basis of a pulse waveform of the inverter, and hence the magnetic flux position inside of the alternating current motor can be estimated and calculated without applying a harmonic wave intentionally.

摘要： In order to supply an AC motor control apparatus which identifies the type of motor automatically, the AC motor control apparatus has a motor type identification means by which the type of motor connected to the motor control apparatus is identified by issuing the appropriate voltage command for motor type identification and judging from the detected current whether the motor rotor is equipped with a magnet and has magnetic salience. The AC motor control apparatus has a control scheme selection means which selects the appropriate control scheme according to the above-identified type of motor and controls the driving of the motor.

摘要： An electric motor drive device 1000 includes: an inverter 3 that drives a motor 4, a voltage division circuit 2 that serves as a neutral point potential detection unit that detects a neutral point potential of a stator winding of the motor 4; and a controller 1 that estimates a rotor position of the motor 4 based on the detected neutral point potential, and that controls the inverter 3 based on an estimation result. A ground potential of the controller 1 is set to a negative side potential or a positive side potential of a DC voltage that is supplied to the inverter 3. The voltage division circuit 2 detects the neutral point potential with reference to the negative side potential or the positive side potential. The controller 1 estimates the rotor position based on a difference between a first neutral point potential detected during the ON/OFF operation of the inverter 3 and a first fixed reference potential (⅔)Emax, and based on a difference between a second neutral point potential detected during the ON/OFF operation and a second fixed reference potential (⅓)Emax.

摘要： The invention relates to a small size and lightweight linear motor having small thrust ripples, in which the magnetic attraction working between an armature and a mover is canceled out and therefore is small. A thrust generation mechanism includes a stator (3) and a mover (5). The mover (5) includes permanent magnets (4) installed in a row so that the magnetic poles at the front and backsides of the magnets are alternately reversed along the traveling direction. The stator (3) includes upper and lower pole teeth (6), (7) having a plurality of magnetic poles (2) and arranged so as to sandwich the permanent magnets (4) of the mover (5), cores for connecting the pole teeth, and a winding (1) wound around a set of a plurality of the cores. Thrust ripples are reduced by adjusting the magnetic pole pitch (Pc) of the magnetic poles (2).

摘要： A synchronous electric motor drive system capable of driving at speeds near zero is provided. An energization mode determination unit switches six energization modes successively based on a terminal potential detected of the de-energized phase of a three-phase synchronous electric motor or on a stator winding wire connection point potential (neutral point potential) detected of the three-phase synchronous transmission unit. A voltage command correction unit corrects by a correction amount ΔV an applied voltage command destined for the synchronous electric motor to supply the synchronous electric motor with a repeated waveform of a positive pulse, negative pulse, and zero voltage as a line voltage waveform of the energized phases in each of the six energization modes, the positive pulse voltage being polarized to cause the synchronous electric motor to generate a forward rotation torque, the negative pulse voltage causing the synchronous electric motor to generate a reverse rotation torque.
