The variable-frequency control of motor is an effective means of saving energy,which plays an important role of improving the efficient use of motors.Based on this,the explosion-proof variable-frequency control method for composite explosion-proof high-voltage induction motor is designed in the following aspects.The explosion-proof variable-frequency parameters of induction motor are obtained,and the variable-frequency control model of the motor is established according to variable-frequency parameters.The magnetic field of motor rotor is directionally controlled,and the speed regulation range of motor is adjusted.According to the output results of variable-frequency control model,the directional control of the induction motor is carried out to obtain the directed spatial position of the magnetic field of motor rotor.The power consumption of the motor during operation is reduced,thereby the precise control of explosion-proof frequency conversion of the motor is realized.A comparative experiment has been adopted to verify the effect of controlling power consumption of the motor rotor method.The experimental results show that this method has a good energy-saving effect,which has a great promotion value.
