The linear motor has been a relatively recent addition to the electric motor world, considering the age of the ac motor is just about 100 years.  Linear motors have grown up primarily in the semiconductor industry where extraordinary precision and speed is required.  And as with all systems that offer the ultimate in performance, they […]

As more semiconductor machines incorporate linear motors, it is crucial to select the right position encoder. Encoders with optical scanning methods enhance the accuracy, speed stability, and thermal behavior of a direct drive. By Dr. Jens Kummetz, Marketing Application Development, Dr. Johannes Heidenhain GmbH The semiconductor industry continues to demand tighter precision and faster operating […]
