FUNCTIONAL CORRELATION OF PARAMETERS AND CRITERIA OF RATIONAL CHOICE FOR ELECTRIC DEVICE

The existing theoretical and experimental dependences between power, electromagnetic and mass-overall dimension parameters of electric device have been analyzed. The choice of the generalized linear size has been substantiated. Electric device power and electromagnetic parameter dependences on linear size have been obtained and experimentally verified. Criteria of rational choice of electric device and their series have been developed, estimation of their applicability to comparison of electric device and their series made.
