Abstract

227,953. Kuyser, J. A., and Metropolitan-Vickers Electrical Co., Ltd. Nov. 6, 1923. Armatures and field magnets, slot-wedges for. An asymmetrical arrangement of the magnetic centre lines of rotor or stator teeth is obtained by employing slot-wedges consisting of magnetic and nonmagnetic portions, and the asymmetry is balanced over the whole tooth system so as to minimize the wave-form disturbance which is due to the slots. Fig. 2 shows a four-pole rotor in which the slot-wedges 1 each comprise a magnetic portion 2 and a nonmagnetic portion 3, and the relative position of the portions is reversed at alternate poles. In a modification, Fig. 3, the portions 2, 3 of a wedge are arranged in one sense in a part of the slot and in the opposite sense in the remainder of the slot. The wedge may consist of three parts, two of which are magnetic and of dissimilar sizes.
