    摘要: In order to obtain a control apparatus for an AC rotating machine that can reliably and stably start up an AC rotating machine, particularly a synchronous motor using a permanent magnet, in position-sensorless vector control thereof, the control apparatus for an AC rotating machine comprises a steady speed calculator (16) that calculates, during steady state control of the AC rotating machine (3), a rotation angular frequency of an AC rotating machine (3) based on an AC current and voltage commands; and a start-up speed calculator (17) that calculates, during start-up control within a predetermined period after the AC rotating machine (3) has been started up, the rotation angular frequency of the AC rotating machine (3) based on the AC current and the voltage commands; wherein the control apparatus corrects during the start-up control current commands so that the AC voltage amplitude of the voltage commands will be a constant value not more than the maximum output voltage of a power converter (2).

    摘要: A control unit is described for driving an electric motor (M1) adapted to move a movable barrier such as a gate. To improve the barrier control during braking, the control unit comprises a H-bridge topology PWM-modulated switching stage (M4-M5, M7-M8) able to power the electric motor, a feedback loop to adjust the speed of the barrier, and an electrical energy storage element (C2) which is placed in parallel to the H-bridge and is adapted to store the energy coming from the motor during the braking action of the barrier so as to limit over-voltages across the H-bridge.

    摘要: The invention relates to a method for determining the position of the rotor of an electric machine (4) having multiple phases (1, 2, 3) in relation to the stator. According to the invention, the change ∆İ in the time derivative İ of the current I flowing through at least one of the power inputs (1', 2', 3') is determined, said change ∆İ being caused by a change ∆U in the potential U on at least one of the power inputs (1', 2', 3') of the electric machine (4), and a measurement signal that is representative of a position of the rotor is determined from multiple simultaneously or successively determined changes ∆İ.

    摘要: A motor control device includes an estimator for estimating a rotor position of a motor having a salient pole by using a value corresponding to a q-axis inductance of the motor as an operation parameter where an estimated axes for the control corresponding to d-q axes are γ-δ axes, and a controller for controlling the motor based on the estimated rotor position. The estimator generates a deviation between a d-axis and a γ-axis by performing the estimation of the rotor position based on a value between a real q-axis inductance and a real d-axis inductance of the motor adopted as the operation parameter. The controller controls the motor so that a γ-axis component of a motor current supplied to the motor is maintained to be a predetermined value of zero or close to zero regardless of a value of a δ-axis component of the motor current.

    摘要: An electromagnetic actuator includes a stator and a movable body. The stator includes a core provided with magnetic poles and a coil wound on at least one of the magnetic poles. The movable body includes a permanent magnet and supported in such a manner as to make reciprocating in a direction perpendicular to a direction in which the permanent magnet opposes the magnetic poles. The movable body is reciprocated upon applying an alternating voltage to the coil. An electromagnetic actuator driving method for driving the electromagnetic actuator includes performing feedback control of the alternating voltage in which the alternating voltage is applied to the coil during a first half of a control period and in which an induced electromotive force generated in the coil during a second half of the control period is used as a control signal.
