摘要： PROBLEM TO BE SOLVED: To solve the problem of an electric rotating machine for driving a plurality of rotors by a hybrid current that the sum of amplitudes of original currents becomes the maximum amplitude of the hybrid current and thereby an inverter and the like are not utilized effectively. SOLUTION: The controller of an electric rotating machine comprises a phase difference generator for calculating the phase difference command value of the rotor where the maximum value of the hybrid current decreases, a phase difference detector for detecting the phase of each rotor and detecting the phase difference of the rotors based on detected phases, a torque command value generator for generating a torque command value based on the phase difference command value and the detected phase difference, and a vector controller delivering a voltage command value to each rotor based on the thus- generated torque command value. The maximum amplitude of the hybrid current can be limited by controlling the phase difference of the rotors. COPYRIGHT: (C)2004,JPO

摘要： In a method and apparatus for motor control in an electric vehicle, current feedback control from an AC motor is performed using a digital arithmetic unit. The motor control equipment includes a power converter having a maximum output frequency of at least 500 Hz for driving the AC motor, and the digital arithmetic unit outputs an AC voltage command to the power converter based on current feedback from the AC motor up to the maximum output frequency of the power converter. The digital arithmetic unit includes a first subtractor for calculating the deviation between a detected value and a command value for the d-axis current, and a second subtractor for calculating the deviation between a detected value and a command value for the q-axis current. A phase calculator calculates a d-axis phase corresponding to the resistance and reactance components of the impedance of the d-axis, and a q-axis phase corresponding to the resistance components of the impedance of the q-axis. A voltage control calculator calculates control signals for the d- and q-axis voltages, due to the d-axis current deviation and the q-axis current deviation, based on the d-axis phase and the q-axis phase. The AC voltage command is output to the power converter based on the d- and q- axis voltage control signals.

摘要： PROBLEM TO BE SOLVED: To provide a motor control apparatus which eliminates the need for a signal application for the position detection and can achieve the magnetic pole position detection of a synchronous motor while operating an usual PWM (pulse width modulation) control with inexpensive digital arithmetic units such as a microcomputer. SOLUTION: In the digital arithmetic unit 4, there is provided with the position detection means 14 which detects the magnetic pole position of the synchronous motor 1 based on a motor current differential value when the synchronous motor 1 is in a state of short circuit. The unit 4 generates a interrupt trigger signal in synchronism with a PWM signal driving a inverter 3 and starts an A/D converter then inputs an electric current of the synchronous motor 1.

摘要： PROBLEM TO BE SOLVED: To control an alternating-current motor with stability even if counter- electromotive force is increased. SOLUTION: In a step S1, it is decided whether the maximum voltage Vmax that can be supplied from an inverter to the alternating-current motor exceeds the counter-electromotive force Er of the alternating-current motor. If the result of the decision is 'YES', operation proceeds to a step S2. In the step S2, deviation Δidorg is set for d-axis deviation Δid and operation proceeds to step S3. In this step deviation Δiqorg is set for q-axis deviation Δiq to complete a series of processing. If the result of the decision in the step S1 is 'NO', operation proceeds to a step S4. In the step S4, the negative value (-Δiqorg) of deviation Δiqorg is set for d-axis deviation Δid and then operation proceeds to a step S5. In this step, deviation Δidorg is set for q-axis deviation Δiq to complete a series of processing.

摘要： PROBLEM TO BE SOLVED: To adequately control the motor operation by identifying an error of voltage value estimated on the basis of the detected voltage value and current value, and then impressing the predetermined voltage to a coil depending on the motor operating condition through reflection of the identified error. SOLUTION: A motor control device 10 once estimates a voltage value of power supply to a certain value. On the basis of the estimated voltage value, a voltage application control part 204 impresses the voltage for detection. If there is an error between the estimated voltage value and the true value, a voltage for detection of the voltage value that is different from the preset value is impressed. An error of the voltage for detection impressed can be detected with a current flowing into a coil depending on the voltage. Therefore, a voltage compensating part 206 can identify an error of the estimated value of the power supply voltage based on such error. As explained above, the voltage application control part 204 can apply the adequate voltage to the coil by reflecting the identified error.

摘要： PROBLEM TO BE SOLVED: To provide a drive controller for a field winding type synchronous machine which is able to improve the responsiveness of field magnetic fluxes. SOLUTION: A controller 100 fetches a torque command value from an external device and controls the drive of a motor 1000, based on the fetched torque command value. The motor 1000 is constituted in a field winding type synchronous motor also using permanent magnets, and a drive current is supplied to the three-phase coils (armature windings) 1110 in U, V, and W-phases in the motor 1000 from an inverter circuit 200. The controller 100 detects whether or not the motor 1000 is transiently operated, and when the transient operation of the motor 1000 is detected, finds a d-axis current component (a current component for forming the coaxial component with the magnetic field by means of a field winding 1230), based on the then output request and controls the current flowing to the three-phase coils 1110 with the current component. As a result, mutual induction is generated between the field winding 1230 and three-phase coils 1110, and the self-induction (back electromotive force) of the field winding 1230 is suppressed by the mutual induction.
