A direct-drive, linear actuator for a heliostat tracking system

Position Control of Linear Synchronous Reluctance Motor Using a Modified Camel Traveling Algorithm-Based Proportional Integral Controller

“…There is no need for a mechanical transmission when applying the electromechanical force from a linear motor straight to the pay load. Moreover, the linear motor drive systems have less friction, minimal backlash, need no mechanical maintenance, and have a longer lifespan [1][2][3][4][5][6][7].…”
