Abstract

The invention discloses a dynamic characteristic on-line monitoring system in a motor starting process, comprising a power supply, a voltage regulator, a comprehensive test control cabinet, a tested motor, a transient torque, a rotating speed tester, a data collection and analysis device and a control platform. The power supply is an AC power supply; the voltage regulator alternatively regulate load voltage; the comprehensive test cabinet guarantees the stability of the load circuit; the transient torque and the rotating speed tester tests the transient torque and the rotating speed of the tested motor; the data collection and analysis device collects the test data, calculates and measures the energy consumption when the motor is started; and the control platform controls the system and obtains the result. The dynamic characteristic on-line monitoring system in the motor starting process can stably collect high speed data in the motor starting process, measures the energy consumption of the motor and saves the test cost.

Description

technical field [0001] The invention relates to a monitoring system for a motor. More specifically, the present invention relates to an on-line monitoring system of the dynamic characteristics during the starting process of a motor. Background technique [0002] An electric motor is a device that converts electrical energy into mechanical energy. The electric motor has many uses, ranging from heavy industry to small toys. Although there are many types of motor products in my country, their efficiency is generally not high, and there is a serious phenomenon of "big horses and small carts". Therefore, high-efficiency motors have attracted more and more attention, and testing the energy consumption level of motors has also become a topic that people pay attention to. [0003] At present, in the test of AC and DC motors and electric tools, the test equipment such as dynamometer is often used. The dynamometer mainly tests parameters such as torque, speed and output power of the ...
