Electric drives are applied in modern mechatronic systems, their motors are connected to the moving mechanisms by means of various mechanical links. Therefore, there are used toothed, worm - gear or composite speed - reducers, screw, belt and rack bar/link mechanisms as well as flexible shafts and crankshafts or drums with ropes and others. The mentioned above links experience elastic torsion, deformations of bending, tension and springing while transferring the motion of a motor to the mechanism. In majority cases they have specific backlash, without which there could be impossible to transmit mechanical movement at all.
