Nanomotion® Piezo Motor: This piezo motor provides very high resolution in the nanometer range.

Open Loop: The positioning system does not use feedback to determine whether its output has reached the desired target of the input command or process setpoint.
Open loop vs. Closed loop: For open loop positioning, the system practically moves without looking at the actually reached position.

PiezoLEGS® Motor: In general, piezo motors are characterized by very high resolution in the nanometer range.

Roll: Rotation around the X axis
Rotary Encoder: Rotary encoders are in most cases directly mounted on the actuator and detect the circular motion of the motor.

Stepper Motor: The stepper motor is ideally suited for applications with low forces and low speed.
Switches & End Switches: A hall swich uses the hall effect to measure magnetic fields.
