<p>The subject of the invention is a spherical, direct current, cage rotor electric motor which has a stator, composed of an inner part (2) made of a spherical shape, hollow, flux conducting soft magnetic yoke, and a surrounding outer part (3) made of a spherical shell shape permanent magnet, and a spherical shell shape caged rotor (6), made of copper profiles and surrounding the stator. The ends of the copper profiles from disk shaped commutators (10A, 10B), to which brushes (11A, 11B) are coupled. The caged rotor (6) is provided with a stiffening ring (7), and it is surrounded concentrically by permanent magnetic main poles (8), which in turn are surrounded by a shell structure (9) and casing parts (21A, 21B) provided with ventilating openings. The axle of the motor is a splined tububar shaft (1) in which openings (15, 20) are formed.</p> |
