Linear motor with two magnets and a coil carrier having multiple winding areas with each area having a section of a coil wound with one continuous wire with the winding in opposite directions in spaced apart winding areas

摘要

A linear motor includes an assembly of two or more sets of magnets and pole pieces wherein the assembly is coaxially affixed inside of a housing, which results in an air gap therebetween. The magnets are positioned so that each magnet has opposite directions of magnetization relative to its adjacent magnet. The embodiment of the motor includes a coil carrier having a single electrical coil of two or more sections with each section wound in the opposite direction to the adjacent section and positioned into the corresponding winding areas of the carrier. The coil carrier is movably positioned into the air gap and further to surround the assembly, thereby moving along an axial direction of the motor when electricity is applied to the coil.
