Linear Motors

The core of the LinMot drive system consists of the control electronics, the servo drive and the linear motors. LinMot motors are electromagnetic direct drives in tubular form. The linear motion is produced purely electrically and wear-free, without any intermediate coupling of mechanical gearboxes, spindles or belts. The linear motor consists of just two parts: the slider and the stator. The slider is made of neodymium magnets that are mounted in a high-precision stainless steel tube. The stator contains the motor windings, bearings for the slider, position capture sensors and a microprocessor circuit for monitoring the motor.

The internal position sensor measures and monitors the current position of the linear motor not only when it is stopped, but also during the motion. LinMot linear motors can be positioned freely within the entire range of the stroke. In addition, both the travel speed and the acceleration can be controlled precisely. For more complex motions, arbitrary travel profiles can be saved as curves in the servo drive and executed by the motor at the desired speed.

Standard Linear Motors

The standard variant of the linear motor can be used universally, covering a wide range of applications. Many different positioning tasks in the low-voltage range can be performed using the compact drives. The family of motors includes 3 models with various lengths of the stator and the stroke. The user can select a maximum stroke length of 1830 mm and peak force of 1024 N. Because the motor components are encapsulated, the motor is optimally protected, even for intensive applications.

High-Performance Motors

The high-performance line of linear motors have significantly greater performance than standard motors with the same component size and identical dimensions. This is largely due to the ongoing development of the motor windings and the magnetic circuit, and the use of high-performance materials. With high-performance motors, the user has access to nearly double the nominal performance. The higher performance in the same form factor allows power to be increased in existing machines and systems without the trouble of mechanical redesign.

Short Motors

This type of motor is the shortest form factor for LinMot linear motors. Short motors have been developed especially for applications with limited space constraints. The short form factor also means that multi-axis applications can be implemented with several stators on one slider in a very small space. In order to provide the designer with as many options as possible for cable routing, these motors are provided with three covers for the cable outlet on the left, right or front. The motor cable can be plugged in under the cover for quick and easy installation.

Linear Motors 3x400VAC

The linear motors of the P10 series are the most powerful in the LinMot product family. With their higher performance and peak forces of up to 2700 N, the motors place higher demands on the drive units and servo drives. For this reason, LinMot has developed a completely new concept and relies exclusively on the 3x400VAC technology and servo drives with direct power supply from the grid for this motor series. Depending on the application, the motors can also be operated with rectified 1x230VAC.

Motors with Integrated Guide

The linear motors of the type P04 have all the advantages of tubular linear motors and additionally offer the advantage of an integrated guide. The P04 actuator can be equipped with the mechanical accessories known from pneumatics, making the replacement of pneumatics easier. Dynamic and precise movements are the main discipline of this motor type. In addition, transverse loads are absorbed by the integrated bearing so that simple applications can be realized without additional components.
