Abstract

619,093. Inductor alternators. BENDIX AVIATION CORPORATION. Nov. 19, 1946, No. 34304. Convention date, Dec. 21, 1945. [Class 35] The stator of an inductor alternator having a single toothed rotor is axially divided into two parts, an auxiliary part which is permanently magnetized and a main part composed of normal magnetic material and excited by the auxiliary part. In one form, Figs. 1 and 3, the main part 2 and the auxiliary part 3 are separated by a non-magnetic spacer 4 and are both of similar form having poles with teeth 5, 7, 9 and 6, 8, 10 respectively which carry three-phase main windings 11, 12, 13 and auxiliary windings 14, 15, 16 in which the exciting current is generated. A further field coil 17 is wound round the poles of both stator parts. In Fig. 8 (not shown), a control circuit is illustrated in which the windings 14, 15, 16 feed the field winding 17 through a polyphase rectifier. When it has built up, the voltage of the main windings 11, 12, 13 then feeds a further rectifier through a transformer, and this exciting current, which is controlled by a carbon-pile regulator operated by the output voltage of the machine, is added to that supplied by the auxiliary windings 14, 15, 16. In a modified form of the invention in which the laminµ are secured together by rivets, the windings are held in place by bent-up tabs on the stator end plates corresponding to the teeth. In a further modification, the auxiliary windings are dispensed with and the main generator winding is taken round the poles of both stators. A control circuit having a transformer fed rectifier supplying the field winding 17 through a carbon-pile regulator is described for this arrangement, condensers being used to correct the power factor of the load current. A further control circuit is described in which the generator output is rectified to charge a battery, the generated three-phase voltage being used to operate a cut-out relay controlling the carbon-pile regulator. Specifications 398,650, [Group XXIV], and 608,508 are referred to.
