A linear motor produces a translational motion, meaning it deploys its force in a straight line. Small linear motors from FAULHABER do this particularly quickly, efficiently and flexibly. They are also characterized by their very high repeatability. This makes them ideal for tasks where components are continuously moved at high speed on a straight axis or where a defined pressure is exerted. What is a linear motor? The conventional electric motor generates its force from a rotational motion; its rotor and stator are positioned in a circular arrangement. In contrast, the linear motor has a forcer rod rather than a rotor as its moving component. Its forcer rod and stator are virtually "rolled out" and placed on top of each other in their straight form. As a result, with a linear motor, the torque is produced in a straight line and the forcer rod moves back and forth along one axis. How are FAULHABER linear motors designed? In linear motors, the winding can be either the stator or the rotor. The permanent magnets each act as the corresponding counterpart. However, with FAULHABER, the neodymium permanent magnets are always housed in the forcer rod, while the coil acts exclusively as the stator. This design enables small linear motors with a particularly small volume that can also produce a very high torque. The oblong-shaped winding of the linear motor is self-supporting and coreless so that no cogging torque is generated. It is split into three electrically isolated segments and is hollow inside. In this cavity is where the forcer rod moves; the two components are separated by a small air gap.
