摘要： Provided is a method of controlling a vibration motor, in which there are provided: a unit that generates a drive signal for generating elliptic motion; a unit that switches the drive signal with a voltage from a power supply, and changes a pulse width of the drive signal; a unit that detects a current flowing in an electromechanical energy conversion element through the switching unit; a unit that detects a position and a velocity of an object to be driven; and a control unit that controls the respective units, and sets the velocity of the object to be driven. The control unit controls a frequency and the pulse width of the drive signal so as to exercise a maximum output characteristic with respect to a target velocity within a range in which the current detected by the current detection unit does not exceed a given limit value.

摘要： A vibrator (3) is sandwiched between a base block (1) and a stator (2), and a substantially lower half of a substantially spherical rotor (6) is received in a recess (5) of the stator (2). A support member (7) is placed on an upper portion of the stator (2). A preload portion (10) is supported at an end of an angle portion (9) of the support member (7). A spherical member (11) rotatable about multiple axes of the preload portion (10) abuts against a top portion of the rotor (6) to apply a preload to the rotor (6). Driving the vibrator (3) rotates the rotor (6), whereby an output shaft (12) is moved between the preload portion (10) and an annular portion (8) of the support member (7) as a movable range.

摘要： Provided is an ultrasonic motor capable of realizing high torque. When two terminals are selected from a first terminal (31t), a second terminal (32t), and a third terminal (33t) of a vibrator (3), and AC voltages whose phases are shifted by 90 degrees relative to each other are respectively applied through both of those two terminals, vibration is generated in the stator vibration body (S), and elliptical vibration in a plane corresponding to the selected two terminals is generated at each of a step (9) of a first stator (2) and a corner (11) of a second stator (10), which are in contact with a rotor (6). Since the first stator (2) and the second stator (10) form the single stator vibration body (S), the step (9) of the first stator (2) and the corner (11) of the second stator (10) vibrate in the same vibration mode, rotational force is transmitted from both the step (9) of the first stator (2) and the corner (11) of the second stator (10), and the rotor (6) rotates with high torque.
