<p>989,716. Interpole windings for dynamo-electric machines. MASCHINENFABRIK OERLIKON. April 10, 1964 [April 16, 1963], No. 14840/64. Heading H2A. The commutation, in a D.C. machine connected to a network subject to surges or fluctuations, is rendered insensitive to these disturbances by means of short-circuited windings 4<SP>1</SP> embracing each main pole, N 1 or S 1 , and the next adjacent interpole, N 2 or S 2 , in the direction of rotation of the machine. When the fluctuation is severe, e.g. in the case of rectifierfed motors, a continuous winding embracing all the poles of the machine may be shorted by a heat-dissipating resistance (Fig. 3, not shown). The windings may be of low-temperature resistance coefficient material. For reversible machines, two such windings, selectively switched may be used.</p> |
