moteur Dynalam

OBS: On connaît ce moteur sous sa marque de commerce.

CONT: Some motors use an ingenious field system designed for a d.c. machine which operates on thyristor power supplies. The poles used consists of stacks of ""C"" shaped laminations which divide the yoke into four separate parts (for a four-pole motor) which are integral with the opposite halves of adjacent poles. This is called the Dynalam field system with split main poles [developed by the Electro Dynamic Construction Co Ltd] (...). The advantage of this split-pole arrangement is illustrated in Fig. 8.7 which gives a diagrammatic comparison of flux distribution in the field system of Dynalam motors and conventional d.c. machines.
