    • The invention relates to a motor having a cuboid piezoelectric element (1) which carries an actuating member (2) for transmitting a force in an actuating direction (x). In known motors the piezoelectric element (1) is restrained by four restraining elements which are disposed in the plane of vibration (x/y plane) and which exert a preloading force on the piezoelectric element (1) in a direction perpendicular to the actuating direction (x). However, this gives rise to a frictional force between the restraining elements and the piezoelectric element, which reduces the vibration quality and, as a consequence, the motor power. This is avoided by means of the invention, where the piezoelectric element (1) is restrained by means of restraining elements (20, 21, 22, 23) without preloading, i.e. with maximal slidability in the directions (y, z) perpendicular to the actuating direction (x). Preferably, such a motor is used in drive apparatuses, particularly for driving the read/write unit on a pivotable arm or on a translatable slide.
    • 本发明涉及一种具有立方体压电元件(1)的电动机,其承载用于在致动方向(x)上传递力的致动构件(2)。 在已知的电动机中,压电元件(1)被设置在振动平面(x / y平面)中的四个限制元件约束,并且在垂直于致动方向的方向上在压电元件(1)上施加预加载力 (X)。 然而,这导致约束元件和压电元件之间的摩擦力,这降低了振动质量,结果是电动机功率。 这是通过本发明避免的,其中压电元件(1)通过约束元件(20,21,22,23)被约束而不预加载,即在垂直于该方向的方向(y,z)上具有最大滑动性 致动方向(x)。 优选地,这样的电动机用于驱动装置中,特别是用于在可枢转臂或可平移滑动件上驱动读/写单元。

    • A starting-process controller for starting a piezomotor, having a voltage-controlled oscillator, a power output stage, and a resonant converter. The oscillator generates the control signals required for the power output stage and the resonance converter converts the stepped output voltage from the power output stage into a sinusoidal voltage at the output. The resonance converter drives the piezomotor with the voltage. The motor current that flows when the piezomotor is driven is measured and compared with the phase of the drive voltage in a phase comparator. The comparison output signal is a measure of the phase difference at the time between current and voltage. A phase-locked loop filter smoothes the phase-difference signal for controling the oscillator. The controller includes a start-assisting circuit element that fixes the output voltage from the phase-locked loop filter at start-up and thus applies a constant voltage to the input of the voltage-controlled oscillator.

    • A piezoelectric driving device and a regulation method for a piezoelectric driving device are proposed. Piezoelectric driving devices known so far show a characteristic with which the electric power applied to the motor drops when the load increases. This behavior, which leads to a strong reduction of the range of use of such motors, is counteracted by predefining the amplitude of the excitation voltage so that the effective power does not drop with increasing load. For this purpose the electrical effective power is determined from the excitation voltage and the current flowing through the piezoelectric resonator. Alternatively, with a predefined fixed phase angle between excitation voltage and current a regulation may also be effected in the way that the current is kept to the constant value. A further aspect of the invention relates to a unit for limiting the current flowing through the piezoelectric resonator, so as to avoid this component being damaged.

    • The invention relates to a piezoelectric actuator (1) for driving a movable part (2), for example a rotor, having an elongate piezoelectric resonator (3), which serves to perform longitudinal vibrations and which is acted upon by elastic means (10), for example a spring (10). The elastic means (10) acts upon the piezoelectric resonator (3) mainly in the longitudinal direction (11) and serves to exert a force on the resonator (3) in a direction towards the movable part (2), the resonant frequency of the elastic means (10) being substantially smaller than the resonant frequency of the piezoelectric resonator (3), and the piezoelectric resonator (3) is guided by at least one guide element (4, 5) in a direction perpendicular to its longitudinal direction (11). This enables the resonator (3) to vibrate as freely as possible, which leads to a higher efficiency.
