Linear DC Servomotors

FAULHABER Quickshaft LM Linear Motors

Linear motors from EMS

Linear DC motors provide a powerful, efficient and cost-effective solution for motion control applications. Unlike rotating motors, these motors produce pure linear movements in a single axis.

For many industrial applications this linear movement had been traditionally carried out by pneumatics. While the technology still has its place for some applications, it’s often more favourable to use an electric linear servo motor, particularly where infrastructure is smaller and more intricate.

Typically, a linear servo motor has a threaded lead screw, which is combined with an electric motor, either directly or via a reduction gearhead. The lead screw can be either threaded to accept a matched nut or it can be a ball screw, depending on what’s required.

However, some linear servo motors do not need a lead screw at all. These are linear DC servomotors, where the linear movement takes place via a forcer rod. FAULHABER linear DC servomotors are a recommended choice for many micro-positioning applications. Featuring little-to-no static cogging torque and class-leading service life, there are several options to meet the individual requirements of an application.

FAULHABER Quickshaft® linear DC motors

QUICKSHAFT® Linear DC servomotors from FAULHABER bring linear motion to new dimensions. These high performance, miniature, linear motors consist of a solid stator housing and coil assembly and a multi-pole magnetic forcer rod, with power magnets that help the motor achieve its excellent force and dynamic speed performance.

For instance, at just eight millimetres (mm) wide and 33 mm long, the LM 0830 delivers peak force up to 2.74 N and positioning control of the linear servo motor is realised through integrated Hall sensors. The motor is ideal where high precision linear movement in the most compact dimensions is vital, such as medical imaging and diagnostic systems, lab automation and a variety of robotics. Elsewhere in the range are the LM 1247 and LM 2070, offering peak forces up to 30N and linear speeds over two metres per second.
