The commands of AC motors has a great impact in many technical applications like transportations, home devices or industrial automations, and recently even in recherche studies. The frequency regulation advantages can't be full exploited without an appropriate control strategy. This paper recommends to the experts and to the users of command systems with frequency converters the usage of speed command and position command to the variable frequency drives. There are analyzed also the commands without position transducers, speed transducers or flux transducers based on approximately results. There are included also logic elements and it's proves how the velocity evolution of the technology command of electrical machines in different branches of the world economy finds a specific field in modern electrical applications.
