Motion Controllers control the velocity and position of machines. These controllers can be implemented with the help of both analog and digital computers. A motion controller comprises of load, prime mover, sensors and controlling machine for proper functioning of prime mover and load. Moreover, it is used to accomplish speed accuracy, increased position, fast reaction time, smooth movements, cost reduction, integrated automation, improved efficiency and consistency, elimination of hazards and better diagnosis and troubleshooting among others. These devices incorporate high force magnet materials, precise dimensional tolerance and innovative design machines. Motion controllers are widely used in printing, packaging, textile, assembly industries, semiconductor production and many other automation systems.
