Summary:The development of four standing wave miniature ultrasonic motors is described, which use piezoceramics based on PZT-Pb(Mn,X)O3 (X = Sb, Nb). The design concepts included: simplified structures to reduce the number of components; simple poling configurations to minimise stress to the ceramic component; and the use of standing waves designs to reduce the drive circuit complexity. The designs are: a windmill motor, based upon a disc with a series of radial fingers; a PZT tube with four segmental electrodes uniformly poled in the radial direction, which executes a combined rotary and bending action; a metal tube motor, utilising a metal cylinder to replace the PZT and so reduce cost; and a shear-type consisting of a PZT disc stator poled in the radial direction, to which is attached a toothed metal ring driving the rotor by friction. 16 refs.
