Schaftmotor

The linear shaft motor is a linear motor consisting of a shaft and carriage. In this drive, however, the magnets are housed in the shaft and the carriage (forcer) moves along the shaft without contact.

As the winding, which is located in the carriage, completely surrounds the shaft, the entire magnetic flux is utilized. This enables a 0.5 to 5.0 mm non-critical air gap without force fluctuations, as the gap size does not change over the entire cross-section of the device. As a result, the average air gap remains the same size.

Another important difference of the shaft motor lies in the design of the magnetic shaft. There is no gap between the magnets within the cylinder (stainless steel tube). The patented process for this creates a magnetic field that is twice as strong as that of linear motors.

In addition, the shaft motor has no iron core, which also improves synchronization. Nevertheless, the system is very rigid, comparable to that of a linear motor with an iron core. With a shaft motor, you therefore achieve very high rigidity and very good synchronization.
