Abstract:
The authors demonstrate that the Halbach array is highly applicable for magnetic excitation in synchronous machines. To this end, they present the geometry of Halbach arrays in Cartesian, polar, and cylindrical coordinates. They also present the design of a Cartesian linear motor which has been optimized for use in conjunction with a class of high-precision magnetic suspension stages for photolithography. They give analytical solutions for this motor's fields, forces, commutation structure, and power dissipation. Results for the power-optimum thickness of the stator windings are obtained. It is suggested that an equivalent Halbach geometry electromagnet may find utility in areas such as magnetically levitated trains.<>
