1. , high-efficient three-phase asynchronous motor is characterized in that:

  • under the fixed prerequisite of the rated speed n of motor number of pole-pairs p, motor, the following parameter of threephase asynchronous should meet following formula substantially;

    1-pn3000=LrrLrR(rs+rr),Wherein;

    the mutual inductance L between the stator and rotor, equivalent rotor winding phase resistance r r, rotor winding self-induction L r, the equivalent parallel excitation resistance R corresponding, stator winding phase resistance r with the motor iron loss s
