Title: Motor having a Plurality of Speeds which can be Switched Selectively.
IPC: H02K29/00
Filed: 1967-08-18
Abstract: 1,198,526. Electric motors. LICENTIA PATENT VERWALTUNGS G.m.b.H. 18 Aug., 1967 [23 Aug., 1966; 18 Oct., 1966; 15 April, 1967], No. 38095/67. Heading H2A. An electric motor providing two widely different speeds for washing machines has a commutated high-speed armature 13 inside the stator 12 and a low-speed multi-polar induction rotor 14 outside it, both rotors being mounted on the same drive shaft. The induction motor stator is wound for 12 poles and may polechange to six poles e.g. by the Dahlander connection, for distributing the washing prior to spinning. The internal stator poles 15, 16 carry series windings 17, 18 and the induction winding (not shown) lies in external slots 21. Additional two-pole windings 19, 20 on the inner poles and 24 lying in deeper peripheral slots 23, cause some two-pole flux to pass out into the squirrelcage rotor 14. This has the effect of imposing a two-pole induction torque on it so that the spinning-speed may be restrained to 3000 a stable R.P.M. for low-speed spinning. These additional coils may be switched in or out to give the spinning speed required (Fig. 3, not shown). In order to avoid needless brush-wear during induction motoring, the brushes may be raised electromagnetically. In the arrangement shown in Fig. 5, the brush 31 is surmounted by a magnetic ferrule by means of which it is drawn up by coil 37. Alternatively the brush may be on a spring-loaded arm. The inner motor may have a permanent-magnet rotor and be commutated electronically (Fig. 7, not shown). The rotor may be between two stators (Fig. 8, not shown).

PARCOFIL AKT.-GES., 20, Peterstrasse, Z³rich, Switzerland.-(Assignees of Ruka Ges. f³r Patentverwertung; 10, Neum³hlequai, Zurich, Switzerland.) Dec. 19, 1930, No. 38390. Convention date, Dec. 19, 1929. [Class 120 (ii).] In quick-traverse machines for winding bobbins, such as weft and bottle bobbins, and particularly for winding artificial silk, in which the traverse guides are moved step by step to build the bobbins by control mechanism operating without contact with the material, the guide rod is slidably mounted in a member traversed by swashplate and carrying a toothed crown rotated by control mechanism to displace the guide rod. It is desirable that the winding spindle be driven in accordance with the diameter being wound to ensure uniform travel of the material during the winding. The swashplate 18, mounted on a shaft 5 driven from a disc 2 through a wheel 3 and driving the spindles oscillates a member 19 in which a screwed rod 21 carrying the yarn guides is progressed by means of a nut in a toothed crown 22. A long pinion 25 engages the toothed crown 22 and at the end of each traverse is partly rotated by adjustable ratchet gear 30 operated by a feeler 34 on the member 19, or it may be continuously rotated by adjustable gearing comprising stepped pinions from the shaft 5. The swashplate may be displaced longitudinally to effect the build by similar means to that above described for displacing the guide. The nut in the crown 22 is divided and spring-controlled, and may be disconnected by longitudinal movement of a tube 20a, Fig. 7. Guides 37, 38, Fig. 3a, for two spindles are carried by the rod 21 and are guided so as not to contact with the bobbin during the traverse by slots 39, Fig. 1a, in a member 40, which is slidably mounted on a rod 41 and displaced longitudinally with the rod 21 by means of a stop 42.
