Kolb A. Post-repairing tests of reloading ability by dynamic loading method and increasing of fastactivity of the direct current electric drive

The thesis is devoted to development of methods and means post-repairing tests of commutation stability, identification maximum permissible on conditions of commutation of a current of an armarure and allowable speed of its change on the basis of dynamic loading systems. The automated complex is developed, the mathematical model is offered and synthesis of dynamic loading systems is carryed out. The complex system of automatic control МMF of additional poles, on the basis of mathematical model of commutation flow, for elimination of a mismatch in changes of a current of an armature and commutation flow in dynamics and correction of position of an average line of a zone sparkless works at regulation of speed of rotation and presence of a alternating component of a current of an armature is developed.
