Vector Analysis of a Step Electric Drive in the Minimum Loss Mode

The article deals with the load and energy characteristics of a step electric drive, their variability by changing parameters, control methods and forcing processes. The study is carried out using vector analysis in relation to a four-phase step electric motor of magneto-electric type with an active rotor. It is shown that using vector diagrams, built on the basis of known analytical dependencies, allows to obtain mathematical expressions to determine the conditions under which the engine gives its maximum power in the mode of minimum losses. Taking into account the identified conditions, it is possible to organize the control of step electric motors, providing the best energy characteristics. The authors present main results of studying a discrete electric drive with a step electric motor and the features of its control.
