Linear actuator is based on ultrasonic motor technology

PI has introduced the M-272 linear actuator based on its maintenance-free PILine ultrasonic ceramic motor. PILine ultrasonic piezo drives offer an affordable alternative to electromagnetic linear motors and motor-leadscrew combinations when small dimensions and/or high speed are important. With velocities of up to 200mm/s, these drives are fast, compact, and are readily integrated. In addition, PIline motors are self-locking at rest with zero heat generation.

The novel M-272 closed-loop linear drive combines motor, actuator, linear encoder, guiding system and brake in a compact package. Thanks to the integrated guiding system, a payload can be easily attached to the drive rod and positioned precisely.

Features and advantages at-a-glance:

Maintenance free ceramic linear motor
Travel range of 50mm
5µm resolution with integrated linear encoder
Fast: 200mm/sec
High speed and dynamics for fast settling
Self-locking at Rest, no need for external brakes, no energy consumption.
