According to the present invention, electromechanical motors are driven in such a way that contact portions of driving elements (10) are moved along smooth trajectories. The velocity is varied, the average velocity being lower during the time when the element (10) is in contact with a moving object (22) than during the contact free time. Preferably, the main displacement velocity component is non-negligible when switching between sets of elements (10). When stopping the motor, the actuating sets of elements (10) are brought into a voltage-free condition, one set at a time. The contact portions of the elements (10) are lapped with such an accuracy, that the normal force applied between the moving object and the stator (2) is large enough to cause elastic deformations of the stator (2) that are in the same order of magnitude or larger than the accuracy of the lapping. |
