The Power To Change To Improve The Design Of Multi-power Motor Starting Performance Analysis

This topic is dragging the volatility of a single-power induction motor load Can only select a maximum load power motor, In the case of light load motor operation will not reach high rate of efficiency and waste of energy seriously. This topic proposed Multi-power induction of motor design, turn to a 75 kW electric motor product improve have a 75kW,55kW and 45kW more than three power level power induction motor.The topic use Finite element analysis analysised Multi-power induction motor in the starting of the motor stator current-time curve, the rotor current-time curve, torque-time curve, dynamic torque-slip curve and the speed-time curve of the simulation analysis, the motor Running under different power performance characteristics.at the same time use the finite element method analysised multi-power induction motor rotor bar and rotor resistivity changes in such factors as the rotor groove on the motor performance carried out studies to analyze the related factors on motor performance were investigated.The results show that the project design the three-power induction motor to achieve better multi-power motor design, motor under the three power levels are of superior performance, the full realization of the energy efficient design goals.
