The motor comprises two stationary clamps and a moving extender, which uses two piezoelectric stack actuators in push-pull mode with a displacement amplification mechanism. The effect of internal compliance and its effect on the load capacity are investigated. A switching converter is used to provide the voltage supply, and switching amplifiers are used to drive the piezoelectric stacks. These were designed for efficiency, weight and reliability.enPiezoelectric inchworm motorSwitch mode power supplyResonant charge recoveryWeightReliabilityCSIR Conference 2010Conference PresentationWilliams, E., Loveday, P.
