    • PROBLEM TO BE SOLVED: To provide a control device of a motor that can reduce vibration and noise caused by a torque variation. SOLUTION: A rotor-speed/position detecting part 4 detects a motor rotation speed and a rotation position from a current value detected by a current sensor. The variation of torque caused by the variation of a load is defined in a torque pattern storing part 5 as a basic torque pattern that is paired with the rotation position in advance. The rotation position is transmitted to the torque pattern storing part 5. By this, necessary torque is determined by the rotation position (angle). On the other hand, a rotation speed variation detecting part 6 detects the torque variation from the rotation speed variation, and adds proper correction to the basis torque pattern. The determined corrected torque is transmitted to a sine-wave drive control part 9 via a torque pattern correcting part 8, and a sine wave with the corrected torque taken into an account is generated. After that, a base driver 10 transmits a proper motor application voltage signal to an inverter 2. COPYRIGHT: (C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a motor controller capable of preventing an increase in current regardless of the magnitude of a load while suppressing vibration. SOLUTION: In the motor controller, by multiplying an average voltage command corresponding to a variation in the number of revolutions of a motor by a torque control pattern which varies in correspondence with the variation pattern of load torque during one revolution of the motor, the driving voltage for the motor is controlled. The motor controller is provided with: a number of revolution variation width detecting portion 20 which detects the width of a variation in the number of revolutions of the motor; a torque control pattern correcting portion 22 which generates a correction value for torque control pattern based on the difference between the width of variation in number of revolutions detected by the width of variation in number of revolution detecting portion 20 and a specified reference value for width of variation in number of revolutions; and a multiplier 23 which multiplies a torque control pattern by a correcting value generated by the torque control pattern correcting portion 22 to generate a new torque control pattern. The controller is constituted so that the driving voltage for the motor is controlled by multiplying an average voltage command by a new torque control pattern generated by the multiplier 23.

    • PROBLEM TO BE SOLVED: To effectively control at a low cost a switching element under a simple open loop control, without the need for an expensive IC circuit, such as a multiplier or the like. SOLUTION: An AC power 1 is full-wave rectified by a diode stack 2, and the rectified power is supplied to an IGBT 8 via a reactor 3. A reference waveform generator 31 of a CPU controller 21 delays the phase of a sine wave signal Vsin for a predetermined time by a sine wave signal Vsin synchronized with the power 1 output from a synchronizing signal generator 23 and an output voltage command M, and generates a reference waveform signal Vss having an amplitude M. A voltage comparator 32 compares the signal Vss with a triangular wave signal Vmod of an amplitude L, outputs a rectangular signal to an IGBT driver 22, and controls on/off of the IGBT 8. When the IGBT 8 is turned on, a reactor current iL is increased, and energy is charged in the reactor 3. Then, when the IGBT 8 is turned off, the current iL is charged in the capacitor 3 through the diode 4, and supplied to a load 6.
