This paper describes with a new linear synchronous motor (TFIP-LSM) of a transverse flux and interior permanent magnet type, which consists of an interior permanent magnet stator and a mover with a claw pole structure. The dimensional parameters of the motor and the electric efficiency were taken into careful consideration, using FEM simulations and measured values. In recent years, LSMs have been used for semiconductor product equipment, mechanical devices, and chip mounters. The trend has been to conduct research on high-efficiency miniature LSMs. To estimate the performance, thrust density Fv (N/cm3) and thrust constant density G (N2/(W cm3)) have recently been used. Within the last two years, LSMs with G = 0.66−5.1 N2/(W cm3) have been developed. TFIP-LSM is small compared with other LSMs and its thrust density motor constant is also small but the thrust constant density of 2.4 N2/(W cm3) indicates that a high performance has been obtained.
