摘要： It is intended to reduce the amount of computation to be performed by CPU or the required amount of storage space in a built-in memory for timing adjustment of a pulse output signal. A digital multiplying circuit in the phase arithmetic circuit of the pulse generating circuit generates a multiplication output signal by multiplying a phase angle change value in the phase adjustment data register and a count maximum value Nmax in the cycle data register. A digital dividing circuit generates a division output signal by dividing the multiplication output signal by 360 degrees of phase angle for one cycle. A digital adding circuit adds the division output signal and rise setting/fall setting count values and a subtracting circuit subtracts the division output signal from these values. The addition and subtraction generate new rise setting/fall setting count values required to delay/advance the phase by the phase angle change value.

摘要： A substantially spherical rotor can be controlled with accuracy even in a relatively low speed rotation. In controlling rotational motions of a rotor 3 of a spherical ultrasonic motor 1, phases of voltages to be applied to three stators 9a, 9b, 9c are determined to set the direction of a rotation axis of the rotor 3. Frequencies of voltages to be applied to the three stators 9a, 9b, 9c are adjusted to control the rotation speed of the rotor 3. Thereby, control with high accuracy is enabled in a relatively low speed rotation.

摘要： A vibratory actuator includes a piezoelectric element, a driver element provided on the piezoelectric element and a movable body supported by the driver element. A control unit supplies a first voltage and a second voltage at the same frequency to the piezoelectric element. By supplying the first voltage and the second voltage having a difference phase from a phase of the first voltage by 90°, the piezoelectric element is lead to composite vibration of stretching and bending, thereby causing the driver to make an elliptical motion by the vibration and move the movable body. The control unit switches, during a fine mode, a phase difference between the first voltage and the second voltage between 90° and 0°.
