Abstract: A method is provided for damping electromechanical oscillations in an electromechanical system including at least one electric machine operable with an angular speed and a phase of the angular speed being coupled to at least one torque load and producing an electromotive force. The method includes deriving actual values of the electromotive force and adjusting the phase of the angular speed, based on the derived actual values of the electromotive force, in a direction in which an oscillatory behavior of the electric machine is reduced.

Abstract: A method for detecting a potential (Vn) includes stator wirings in a Y connection, and automatically adjusting a relationship with a position of a rotor as a system for realizing rotor position-sensorless stable drive of an AC motor where the three-phase stator wirings are in Y connection in the stop and low-speed ranges. A synchronous motor control apparatus includes a three-phase synchronous motor in which three-phase stator wirings are in a Y connection, and an inverter for driving the motor, wherein the synchronous motor is DC-conducted thereby to move a rotor to a predetermined position, and is applied with a pulse-shaped voltage from the inverter in the moved state so that a neutral point potential as potential (Vn) of the Y connection point is acquired when the pulse voltage is applied, thereby driving the synchronous motor based on the acquired value.

Abstract: When a set duty Dt of a PWM signal is less than a minimum duty (Dmin) that allows for pulse induced voltage detection, the PWM signal in which a duty D1 during a predetermined period is limited to Dmin and in which a duty D2 during the other period is adjusted so as to satisfy Dt=(D1+D2)/2 is applied to the switching elements connected to one of the two phases. When the duty D2 during the other period takes a negative value, the pulse-voltage application target during the other period is changed to the switching elements connected to the other of the two phases, and the duty D1 during the predetermined period is corrected and increased so as to compensate for an actual drop in the duty D2 during the other period corresponding to a dead-time period in a complementary PWM method.

Abstract: An electric linear motion actuator includes: a rotary shaft to be driven by an electric motor; a plurality of planetary rollers kept in rolling contact with a cylindrical surface formed on an outer periphery of the rotary shaft; a carrier which retains the planetary rollers such that the planetary rollers are rotatable about axes thereof while revolving around the rotary shaft, and of which axial movement is restricted; and an outer ring member surrounding the planetary rollers and supported so as to be slidable in an axial direction. Helical ribs are formed on an inner periphery of the outer ring member; and circumferential grooves are formed on an outer periphery of each of the planetary rollers so as to be engaged with the helical ribs. A rotation of the rotary shaft is thus converted to a linear motion of the outer ring member.

Abstract: A motor drive device is provided which allows control to be performed depending on a position of magnetic poles of a rotor even when a motor rotor angle sensor malfunctions. The device controls a motor for driving a wheel of an electric vehicle, depending on the position of the magnetic poles by using an angle sensed by the angle sensor provided at the motor. The device includes an estimator estimating an angle of a rotor of the motor without using a rotation sensor; a sensor malfunction determiner determining a malfunction of the angle sensor; and a switcher causing control to be performed using a angle estimated by the estimator instead of the angle sensed by the angle sensor once the determiner determines that the angle sensor malfunctions.

Abstract: A motor includes a frame, a shaft rotatably mounted onto the frame, and at least one disc mounted onto the shaft. At least one permanent magnet is mounted on the disc, and at least one electromagnet and at least one coil are mounted to the frame in rotational magnetic proximity to the permanent magnet. A battery is connectable to the electromagnet and the coil for energizing the electromagnet and for receiving electrical current from the coil for charging the battery. A relay switch controls the transmission of electrical power from the battery to the electromagnet. A sensor generates a signal to the relay switch to activate electrical power to the electromagnet upon sensing that the permanent magnet is positioned with respect to the electromagnet such that a magnetic force generated by the electromagnet would be effective for inducing movement of the permanent magnet and consequent rotation of the disc.

Abstract: A method and arrangement for determining the position of the drive mechanism of an electric machine from the current supplied thereto. Determination of the position is effected over two independent channels by measuring the three-phase current of the electric machine or motor, converting the measured values to the current space vector, calculating the angle of the current space vector within one electrical revolution, and determining the position of the motor. A current command, the field of which acts in the direction of the flux or field of the drive mechanism or rotor, is added within the motor stator.
