Abstract

Two prototype piezomotors are described in terms of their operational principles, design, construction and some operating characteristics. Both are driven by mechanically amplified piezoelectric stack type actuators. One is a harmonic piezomotor in which the mechanically amplified displacements are used as the wave generator of a harmonic gear drive. The other uses similar mechanical amplifiers to drive a roller clutch motion generator. The requirements for effective mechanical amplifiers are discussed and the performance advantages of piezomotors based on them outlined. It is concluded that such motors can offer useful possibilities for specialist mechatronic applications.
