Abstract

613,475. A.C. motors. BRITISH THOMSONHOUSTON CO., Ltd. May 24, 1946, No. 15829. Convention date, May 25, 1945. [Class 35] The stator of a synchronous motor has radially extending imbricated polepieces adjacent to but axially spaced from a rotor having a ring of segments formed by slotting a disc, the rotor being magnetized so that poles of opposite polarity are formed at the two edges of each segment. As shown, one set of polepieces 13a is on the plate 6 secured to one end of the coil core 4 and the other 12a on a plate 7 secured by its flange to a cup (not shown) to the centre of the base of which the. other end of the core 4 is secured. Projections 27-30 extend through the copper disc 31 which has slots 33 so that only projections 28 and 30 are shaded and these are slightly longer than the others to equalize the flux. The stator cooperates with a magnet rotor, as shown in Fig. 3. In a modification, the shading plate and axial extensions on the polepieces are omitted. The Specification as open to inspection under Sect. 91 comprises also a motor with an uncut disc rotor of hysteresis material. This subjectmatter does not appear in the Specification as accepted.
