Double-sided coreless linear motors have a crucial
role in direct-driven precise linear motion applications. In this
study, an optimum design effort focused on thrust force
production is presented. For an applicable brushless linear motor
structure, winding and permanent magnet (PM) dimensions which
are providing the highest possible force are defined by using finite
element analysis (FEA). It is shown that the most important
problem of an optimum design is arising from placing proper
amount of ampere-turns, i.e. windings, without losing a substantial
value of permanent magnet flux density due to increased air gap.
For obtaining an optimal design, structural demagnetization,
loading demagnetization and fringing flux must be taken into
account. So a trade-off is provided between the winding structure
and the PM assembly.
