Research On Power Measurement Technology Of Three-phase Dynamic Pressure Gyro Motor

Three-phase dynamic pressure gyroscope motor is an important part of gyroscope,which is used to drive gyroscope rotor to rotate at high speed.In order to ensure the stable operation of the gyroscope,a method of monitoring the power value of the three-phase dynamic pressure gyroscope motor is studied in this design,aiming at the three-phase square wave output of the gyroscope motor and the working characteristics of high frequency and low power.This method has simple hardware circuit structure,intuitive data processing method and flexible design changes.It can fully meet the power test requirements of three-phase dynamic pressure gyro motor,and solve the practical problem of less power test products for three-phase dynamic pressure gyro motor.The hardware of the project uses STM32 as the main control chip,collects and calculates the input voltage and current signals separated by mutual inductance circuit,then outputs the active power value of the three-phase power supply in the form of current signal,transmits the power value to the computer through the acquisition card,and displays it with Labview software.
