Asynchronous motor test system based on labview platform

Abstract

The invention provides an asynchronous motor test system based on a labview platform. The system comprises a power supply transformer, a rectification unit, a frequency converter 1, a four-quadrant frequency converter 2, a frequency converter 3, a tested motor, an accompany test motor, and a test system monitoring module. The power supply transformer is connected with an electrical network. The rectification unit is connected with the frequency converter 1, the four-quadrant frequency converter 2, and the frequency converter 3. The frequency converter 1 is connected with a filter 1 and then is connected with the tested motor. The tested motor is connected with the accompany test motor through a coupler. The accompany test motor is connected with the four-quadrant frequency converter 2 or the frequency converter 3 according to an actual condition. The filter 1 and a filter 2 are connected through a parallel operation control unit. The test system monitoring module is used for monitoring state and performance parameters of the frequency converter, the test motor and the accompany test motor. Simultaneously, acquired data is sent to a host computer of the system, and functions of data real-time acquisition and processing, real-time display, storage playback, automatic determination and the like are realized. According to the test system, each performance test of an asynchronous motor in a wide power scope segment can be realized.

Description

technical field [0001] The invention relates to the technical field of motor production, in particular to an asynchronous motor testing system based on a labview platform. Background technique [0002] Asynchronous motors are widely used in industrial fields, and can be used to drive various general machinery such as compressors, water pumps, crushers, machine tools, transportation machinery and other mechanical equipment, in various industries such as mining, machinery, metallurgy, petroleum, chemical industry, power stations, etc. Used as prime mover. The performance of the asynchronous motor is directly related to the normal production and product quality of the user. [0003] In the development process of new asynchronous motors, or before the asynchronous motor leaves the factory, its performance must be tested to determine whether its performance meets the needs. Therefore, it is necessary to prepare a set of test equipment as a performance test method for asynchronou...

Problems solved by technology

[0004] Manufactured asynchronous motors have certain output power requirements, ranging from hundreds of watts to hundreds of kilowatts, even up to megawatts. Such a wide power range requires a lot of test equipment and test benches with different power levels, resulting in Large fixed capital investment and large floor space

On the other hand, in the test process of high-power motors, if energy recovery is not adopted, the cost of electricity consumption during the test process will be very high
