Piezo motors are linear or rotary motors offering high precision and blocking at rest. These properties make them suitable for long stroke micro positioning applications.
CEDRAT TECHNOLOGIES has experimented different kinds of piezoelectric motors either by retrofitting / testing standard piezomotors or by developing new original concepts, in the context of space applications or fine instrumentation projects:
The following examples show various prototypes and customised products. To learn more about our piezo motors see our related publications on rotating piezo motors or on linear piezo motors. A developer kit based on the SPA30uXS is also available.
The Stepping Piezo Actuator SPA30uXS is a new high-force density non-magnetic stepping linear micro piezomotor : Mass < 1gr ; Blocking force at rest > 0.5N ; Max actuation force > 0.2N ; Stroke > 3mm ; Speed > 50mm/s ; Resolution < 1nm
