Abstract
In a unipolar transverse flux machine, to achieve a modular construction, which is favorable from a production standpoint, the stator ( ) and the rotor ( ) have an equal number of identical stator modules ( ) and rotor modules ( ); the rotor modules ( ) are firmly seated, in alignment with one another, on the rotor shaft ( ), and the stator modules ( ) are rotated by a rotational angle from one another in the housing ( ). When there are two stator modules ( ), the rotational angle is 90° electrically, and when there are m stator modules ( ), the rotational angle is 360°/m electrically, where m is an integer and is greater than 2. Each stator module ( ) has an annular coil ( ), disposed coaxially to the rotor axis ( ), and U-shaped stator yokes ( ) that fit over the annular coil, along with short-circuit elements ( ) disposed between the stator yokes. Each rotor module ( ) comprises two rotor rings ( ) with teeth on the outside, and between them a permanent-magnet ring ( ), magnetized unipolarly in the direction of the rotor axis ( ).
