Permanently excited alternating current synchronous machine for rotary and linear application, has coil with magnetizing parts surrounded by receiver and magnetically conductive inference elements of magnetic circuit

摘要

The machine has a coil with magnetizing parts surrounded by a receiver and magnetically conductive inference elements (Sr) of a magnetic circuit. A receiving arrangement comprises pairs of elements of permanent magnets (M) magnetized in a longitudinal direction, where the permanent magnets form groups of same direction of magnetization, and the number of the pairs of elements for each pole spacing is two or more than two. The pole spacing results from the sum of the longitudinal dimensions of the pairs of elements of same direction of magnetization.
