摘要：The method employs a three-phase invertor (WR) which feeds the machine (IM) and has output current transformers (7,8) and voltage transformers (9,10) feeding multipliers (11,12) and comparators (13,14) followed by an integrator (I) and flux component convertor (KW). Switching state variables (Sa'-Sc') representing individual voltage space vectors are processed by a signal switching circuit (SU). The two-point torque regulator is associated with a line current limiter which acts only when the maximum line current exceeds a predetermined threshold.
