Transversal flow machine in accumulator arrangement

Claim 1

An alternating current motor comprising: a rotor having an exciter part arranged therein, said rotor rotatable in a given direction, and a stator with two fixed armature coils running in the direction of rotation, wherein each of the armature coils is surrounded on three sides by a plurality of substantially U-shaped soft iron elements arranged transversely in each case to the appertaining armature coil, the mean spacing of two successive soft iron elements corresponds in each case to two pole divisions, the free ends forming the stator poles of the soft iron elements of the one armature coil bound defining one side of an air gap and the free ends forming the stator poles of the soft iron elements of the other armature coil defining the other side of the air gap, the free ends of the soft iron elements on both sides of the gap are shifted by one pole division against one another in the direction of rotation, the exciter part comprises in the gap toward both sides of the gap and opposite the stator poles a permanent-magnetically excited series of soft iron blocks forming a series of exciter poles with the polarity of the poles alternating along the direction of rotation, characterized in that: between the soft iron blocks of the rotor exciter part in the gap plane along and/or transverse to the direction of rotation there are arranged permanent magnets magnetized with alternating polarity, and that the face surface of the permanent magnets lying opposite the soft iron blocks is greater than half the face surface of the exciter poles formed by the soft iron blocks on the air gap.
