| Abstract: | For frequency control of motor speed,voltage which follows frequency regulaling law,relates to load performance.In order to bring the ability of motor torque into full play,keep main flux invariant or motor overload ability invariant,use constant torque and constant power as frequency control of motor speed to ensure steady output mechanical charatteristic of the motor. |
