MULTIPHASE SYNCHRONOUS-DESIGN ELECTRIC MACHINE ENERGIZED BY PERMANENT MAGNETS

摘要

by the arrangement of the soft magnetic materials, and magnetic and permanent magnets (4) in the rotor, the stator winding is fed by a converter so that an additional magnetic field is generated along the longitudinal (b) field. mental excitement (be) through the coil of the armature current passes through it.the magnetic field (b) is added to the added or subtracted from the basic field excitation (be) in the direction of the longitudinal axis, polar, which allows a greater range of adjustment of the field.the rotor (1) of the electric machine excited by permanent magnets is divided into at least two parts (2, 3) of different constructions and axially arranged one behind the other.the first section (2) is provided with permanent magnets (4), the second section (3) includes a soft magnetic material, which extends to the gap in order to drive the additional longitudinal magnetic field (b1) generated by the winding of the armature. we avoid this separation in space, an overlap between the two fields.this machine can be used as a practice range for adjusting the speed of rotation, such as training of machinery or vehicles.
