Motor parameter detector

Abstract

The invention discloses a motor parameter detector to solve the technical problem of real-time detection of motor parameters. The detector comprises a hardware platform composed of a central processing unit (CPU) micro control unit (MCU) module, a measurement module, a display module, a communication module and the like. A C8051F340 single chip microcomputer serving as the CPU forms a main control circuit, wherein the single chip microcomputer is connected with a digital signal processor (DSP) chip for power energy metering through a software process improvement (SPI) bus, is connected with a torque sensor, a rotation speed sensor, a winding temperature rising sensor, a liquid crystal display (LCD) screen, a keyboard and a relevant interface circuit, and communicates with principal computer (PC) software through a 485 network, so that further analysis and management of uploaded data are achieved on computers, and a human-computer interaction is achieved; and the DSP chip for power energy metering is connected with a voltage transformer and a current transformer so as to detect three-phase voltage and current signals. The motor parameter detector has the advantages of being capable of collecting electrical parameters for alternating current induction motors and synchronous motors, high in automation degree, and simple to operate, and guaranteeing the accuracy of measurement results and the stability of the system operation on the basis of increasing the instrument operation speed.

Description

technical field [0001] The invention relates to a motor parameter detector. Background technique [0002] In the early days, domestic manufacturers used conventional electrical instruments to measure motors, and their working methods were manual operation, manual reading, manual recording, and manual data processing. Its disadvantage is that some parameters such as speed and torque cannot be directly measured, and the error is large, the work efficiency is low, the measurement data is scattered, the measurement result is low in accuracy, and the real-time performance is not high. [0003] With the development of computer technology and the emergence of large-scale integrated circuits and microprocessors, the motor testing technology has entered the stage of microcomputer testing. A series of instruments such as a thermometer are used to detect the motor parameters. The computer motor test system has the advantages of fast measurement speed, high precision, strong real-time...
