The M-272 fast linear actuator manufactured by PI (Physik Instrumente) L.P. for automation applications is based on a maintenance-free PILine ultrasonic ceramic motor. PILine piezo drives offer an alternative to electromagnetic linear motors and motor-leadscrew combinations when small dimensions and/or high speed are important. With velocities of up to 200 mm/s, the drives are fast, compact and readily integrated. PILine motors are self-locking at rest with zero heat generation, eliminating the need for an additional motor brake and consuming no energy. The M-272 closed-loop linear drive combines motor, actuator, linear encoder, guiding system and brake functionality in a compact package. The integrated guiding system allows the payload to be attached to the drive rod with precise positioning.
