Abstract
A method for accelerating or decelerating a moveable body which body is moved by urging a piezoelectric micromotor to the body in a first direction so that a contact region of the piezoelectric motor is pressed to the body and exciting vibrations in the piezoelectric micromotor at the contact region in the first direction and in a second direction along a direction of motion of the body, said vibrations having a first amplitude in the first direction and a second amplitude in the second direction, the method comprising: a) for acceleration, gradually changing a ratio between the second amplitude relative to the first amplitude from substantially zero to a desired non-zero value; or b) for deceleration, gradually changing the ratio between the second amplitude relative to the first amplitude from a non-zero value to substantially zero.
