摘要： An ultrasonic motor drive apparatus includes a transformer having a primary coil and a secondary coil which drives a piezoelectric body of an ultrasonic motor. One end and the other end of the primary coil are connected to the drains of MOSFETS. The gates of the MOSFETs are connected to receive switching signals to alternately turn on and off electrical currents which flow in the primary coil. The sources of the MOSFETs are connected to the ground through ferrite beads, respectively. The ferrite bead generates a counter electromotive voltage so that the surge voltage which develops on the drain of the MOSFET at the time of turning off of the MOSFET is suppressed and high frequency oscillations are suppressed.

摘要： A drive device for a vibration actuator which stably drives the vibration actuator and prevents the occurrence of the cogging phenomenon. The vibration actuator provides a drive force by supplying a voltage to an electromechanical energy converting element which converts electrical energy into mechanical energy to produce mechanical vibratory motion. The drive device for the vibration actuator includes a voltage generating device to generate an alternating voltage which is impressed on the electromechanical energy converting element, and a voltage control device to control the alternating voltage of the voltage generating device such that the current supplied to the electromechanical energy converting element from the voltage generating device becomes constant. The voltage control device changes the output voltage value of the voltage generating device according to the excitation state of the electromechanical conversion element. The voltage control device controls the alternating voltage such that amplitude value, the effective value, or the average value of current supplied from the electromechanical energy converting element is constant. The drive device for the vibration actuator may also include a direct current power supply, a direct current-alternating current converter to convert the direct current voltage to an alternating voltage and to impress the alternating voltage on the electromechanical energy conversion element.

摘要： The utility model belongs to the field of the non-beam pumping unit, specifically relating to a non-beam pumping unit driven by a biaxial motor. The non-beam pumping unit driven by a biaxial comprises a base, a tower body and a drive mechanism.
