ELECTRIC MACHINE

摘要

The invention relates to the field of electrical engineering, and specifically to designs of electric machines which can be used as electric generators or motors. The invention allows one to improve the technical parameters by increasing torque and power capacity while reducing mass and heat losses. The device comprises one circular row of permanent magnetic poles (1) and a circular row of electromagnets (3 magnetic-force-conducting elements (4) of which have central pole part (18) and two lateral pole parts (19, 20) connected to the central pole part (18) and spaced from opposing (in the direction which is essentially perpendicular to the rotation axis) sides of the central pole part. Winding (5) is situated upon central pole part (18). The part of winding (5) situated between the pole parts of the magnetic-force-conducting element is more than half the length of the whole winding. Central pole part (18) may have at least, one groove. The distance (L 1 ) between the centers of adjacent pole surfaces of the magnetic-force-conducting element (4) is set depending on the angle between the magnetic poles in the circular row. The angular dimension of the pole surface of the lateral pole part is set depending on the angular dimension of the pole surface of the central pole part. (4 independent claims, 16 illustrations)
