Linear motors

Linear motors can, in principle, be any type of motor as long they produce a linear motion instead of a rotary one. Many motors in this category are fundamentally rotary motors in which, for example, the motor shaft has been replaced by a screw, but there are also other types of motors that produce a linear motion. One example of this are the linear motors in the QuickShaft model range, which have a motor housing with windings that move along a magnetic rod. This linear motor produces a linear motion without detouring around a rotary motion.

Small linear motors are used in everything from actuators through XY tables to the dosing of drugs (in pumps) or for placing electronic components in SMT machines. Larger linear motors are used for heavy lifting or to move large loads horizontally at high speed and high precision at the same time.

Linear motors are frequently combined with some type of motor controller, which keeps track of speeds and especially position.

We often find a linear motor from our standard range that suits the applications of our customers, but sometimes something else is required. There is then the option to customise a motor, for example with a tailor-made nut on a linear motor with a lead screw or ball screw.

QuickShaft

This range of motors takes linear motion to completely new levels. These miniaturised and high-performance linear motors consist of a solid stator with self-supporting winding and a multi-pole magnetic bar. Highly efficient magnets help the motors to achieve an excellent dynamic performance and power.

Non-captive stepper motor

This type of motor is based on a stepper motor in which the shaft has been replaced by a nut that rotates with the rotor. A lead screw has then been fitted through this nut, which when prevented from rotating produces a linear motion. Available with various windings and in sizes ranging from 20 mm to 86 mm square. Produces up to 1700 N.

External linear stepper motor

A stepper motor in which the rotor shaft is a lead screw. A nut is fitted on the lead screw, which when prevented from rotating produces a linear motion. Available with various windings and in sizes ranging from 20 mm to 86 mm square. Produces up to 1700 N. The lead screw can be coated with Teflon for lower friction on request. This type of motor also provides a number of options for customisation.

Stepper motor actuator (captive)

A fully finished actuator based on a stepper motor in sizes ranging from 35 mm to 57 mm square. The actuator can deliver just under 1000 N continuously depending on the model and pitch.

Miniature stepper motor with lead swrew

The miniaturised stepper motors from FAULHABER can be combined with lead screws to provide a linear motion system with high precision, a long service life and high force to volume ratio. Diameters ranging from 1.2 mm to 3 mm. Up to a force of 35 N depending on the model and motor.

Servo motors with ball swrew

FAULHABER’s powerful servo motors can be combined with the addition of a 22 mm or 32 mm ball screw. Thanks to their high precision, these are ideal for positioning in applications requiring high precision. In addition, the motors can be supplemented by a high resolution encoder and integrated motor controller to create a powerful system for demanding applications in optics, automation or medical technology.
