Design of high performance linear brushless DC motor with ironless core

In this paper, a high performance linear brushless DC (BLDC) motor for very low power applications is presented. The motor is designed such that the core is slotless and ironless. This ironless core eliminates the attraction force between the rail and the forcer as well as it reduces the magnetic losses. Better dynamic performance is also achieved because of the lower winding inductance. The motor geometry, winding configurations, designing …
