Inertial & Inchworm piezoelectric motors: Design and Motorization selection key aspects

Abstract:
Piezoelectric motors have gained increasing prominence in various applications due to their unique capabilities and advantages. These motors are adapted for applications which require non-magnetic and radiation compatibility, high force/volume ratio, good unpowered stall force and low power consumption. Cedrat Technologies (CTEC) have developed inertial and inchworm motorization for a wide range of application such as Space, Defense and Nuclear. Each motorization solution has its own advantages and disadvantages which are discussed in this paper. Key aspect for the design and key element for the motorization selection are presented below.
