Motor power measurement and calculation system based on motor refrigeration

Abstract

The invention relates to the technical field of motor power measurement and calculation, and particularly discloses a motor power measurement and calculation system based on motor refrigeration. The system comprises an upper computer and a control panel. The upper computer is electrically connected with the control panel through a data acquisition card, and the control panel is electrically connected with a signal conditioning circuit, a relay, a flow sensor, a key and an indicator light; and the signal conditioning circuit is electrically connected with a voltage sensor, a current sensor anda temperature sensor, and the relay is connected with an electromagnetic valve, a water pump, a refrigeration fan and a heater. According to the invention, the heat power generated by motor operationis measured by using a cooling circulation system which must be adopted during motor operation, so that the motor operation power is calculated; the system also has a preheating function, and can preheat the motor when the environment temperature is too low, thereby reducing the wear of the motor, and guaranteeing the safe operation of the motor. Finally, a system which is low in cost, high in reliability and high in intelligent degree is formed.

Description

technical field [0001] The invention relates to the technical field of motor power measurement and calculation, in particular to a motor power measurement and calculation system based on motor refrigeration. Background technique [0002] With the development of science and technology and the progress of the times, motors play an increasingly important role in all walks of life in modern society. Whether it is the power industry, or in the machinery manufacturing industry or other light and heavy manufacturing industries, motors are widely used. For example, many motors are equipped in power plants, printing plants, and various household appliances. Motors have been deeply involved in people's lives for a long time, and it has become a necessity to improve production efficiency and technological level as well as improve people's quality of life. Therefore, the performance of the motor has become an important factor to measure the stability of the control system composed of ...

Problems solved by technology

This system of measuring motor power can obtain the output power of the motor, but due to the great difficulty in torque measurement, all current methods of measuring torque are not economical and have great limitations in measurement, and loss will be lost during the measurement process. Part of the output power, it is difficult to measure the output power of the motor under all working conditions
