The M-272 linear actuator for automation is based on a maintenance-free PILine ultrasonic ceramic motor. With velocities of up to 200 mm/sec, these drives are fast, compact, readily integrated, and self-locking at rest with zero heat generation, eliminating the need for an additional motor brake.
The closed-loop linear drive combines motor, actuator, linear encoder, guiding system, and brake functionality in a single package.
Features/advantages include a travel range 50 mm; 5-µm resolution with integrated linear encoder; high speed and dynamics for fast settling; no energy consumption, and OEM driver electronics for ultrasonic motors are available.
