Features of torque production of synchronous electric drive with direct torque control of mining machines

[摘要] In article, the direct torque control method of the synchronous electric drive is considered. This control method is characterized by high performance, robustness and small frequency of switching of keys of the converter. The algorithms and structure of direct torque control of the synchronous electric drive allow creating its operation modes by impact on the form of a triangle with sides: flux linkage of the stator, a rotor, and resultant flux linkage.
