The work is devoted to topical issues of improving linear piezoceramic motors, scanning probe microscopes. Peculiarities of designing piezoelectric motors, namely the coordination of the shape and geometric parameters of the pusher with a piezoceramic plate (stator) are described. The rational ratio of the length of the pusher top to the length of its base is determined. The rational height h of the coaxial pusher of a linear piezoceramic motor is established. The results of the investigations made it possible to increase the oscillation amplitude of the stator of a linear piezoceramic motor by a factor of 4.5. The adequacy of model calculations is confirmed by experimental studies. The results obtained can be used in the design of piezoceramic motors.
