摘要
Vector control of an induction motor with torque control function eliminates the need for a torque sensor, which reduces the cost of the system and simplifies the design of the electromechanical part of the load stand. This approach is applicable to study the characteristics of a BLDC machine operating in both motor and generator modes. A mathematical model of a BLDC machine, loaded by an induction motor fed by frequency converter is built in the SimInTech dynamic modeling environment. Speed-torque curve of BLDC machine is obtained. Comparison of the values of the characteristic points with the motor specification data proves the correctness of the mathematical model and the adequacy of the results.
