The composition of the motor integrated test system is briefly introduced. Based on this system, the software development function requirements of the motor test system are analyzed, and the system software architecture is designed. Based on the software architecture, the C# programming language of the Visual Studio 2019 development platform is used to develop the motor integrated test system software. The design of the software human-machine interface is introduced in detail. The three-phase asynchronous motor is taken as a typical case, and the functional design and the realization of the typical test project of the test software are described in detail.
