    摘要: Speed fluctuations are decreased with a simple method even when a stepping motor (100) having comparatively large torque fluctuations is used. A drive pulse modulating unit (112) which modulates the frequency of a drive pulse to be inputted to the stepping motor (100) is provided. The drive pulse modulating unit (112) modulates the constant frequency of the drive pulse such that the frequency of the drive pulse within excitation-phase one cycle of the stepping motor (100) is: low for a period that is, by 1/8 cycle of the excitation-phase one cycle, before an excitation phase where the vibration of the stepping motor is the maximum; and high in an excitation phase that is by 1/2 cycle subsequent to the excitation phase where the drive pulse frequency is low.

    摘要: The invention relates to a method for controlling an electric motor (M) associated with a servo-pump (200) of an industrial machine in order to modify a hydraulic pressure applied by the servo-pump (200) to a hydraulic load (10). The electric motor can be moved on the basis of electric actuation signals generated by an electronic control unit (100). The method comprises the steps of:
    - providing the electronic control unit with a first signal (Pfed) indicative of a current pressure value detected in a hydraulic circuit (11) of the servo-pump;
    - providing the electronic control unit with a second signal (Pref) indicative of a reference pressure value;
    - providing the electronic control unit with a third signal (Sfed) indicative of a displacement (θ) angle of a rotor of the motor, detected on a plane orthogonal to the rotation axis from a reference position;
    - generating, based on said first, second and third signals, a fourth signal (BTref) indicative of a driving torque value which can be applied to the motor and associated with a torque control signal (Tref) configured to control the movement of the motor of the servo-pump. The method further comprises the following steps carried out by the electronic control unit:
    - comparing the first and the second signals to generate a pressure error signal (PE);
    - multiplying the pressure error signal by a trigonometric function calculated in relation to the displacement angle obtained from the third signal to generate a first transformed signal (PEt);
    - integrating over time the first transformed signal to generate a first integrated signal (PEint);
    - multiplying the first integrated signal by the trigonometric function calculated in relation to the sum of said displacement angle (θ) and an offset angle (θ off ) to generate a second transformed signal (Tff), which is representative of a compensation driving torque value;
    - adding the second transformed signal to the fourth signal to generate the control signal (Tref).

    摘要: A motor control device is provided, which drives a two-phase synchronous motor. The motor control device includes: control current waveform generating means which generates a control current waveform by superposing a fundamental sinusoidal wave and a reluctance torque correction waveform that suppresses the fluctuation of the reluctance torque of the two-phase synchronous motor; and current control signal generating means which generates a current control signal for supplying a current to the windings of the two-phase synchronous motor according to the control current waveform generated by the control current waveform generating means. The reluctance torque correction waveform may have a waveform profile such that an original waveform having a frequency twice that of the fundamental sinusoidal wave and having a phase matched with that of the fundamental sinusoidal wave is full-wave-rectified to the same sign as or a different sign from that of the fundamental sinusoidal wave.
