| Abstract: | To ensure that the three-phase gyroscope motor can work normally, it＇ s necessary to measure the effective value of its AC driving signal. The measurement principle of the voltage effective value for the non-sinusoidal periodic signals is analyzed. An automatic measurement system of the voltage effective value for three-phase gyroscope motor based on the control of C8051F020 MCU is introduced. The system is composed of the conversion circuit of voltage effective value, data acquisition circuit under the control of MCU, LCD and alarm output circuit. The system has been successfully applied in the drive signal detection of three-phase gyroscope motor. |
