| Summary: | Statistical spread of the electrical device parameters appears often to be a problem for their operation analysis and a precise determination of their optimum modes. Under such conditions, mathematical algorithms permitting to diagnose these devices with the accuracy sufficient for the engineer analysis are required. A new algorithm of calculating the moment-slip characteristic of the three-phase asynchronous motor is offered. It permits to determine its maximum torque and critical slip. To this end, the initial characteristic section obtained experimentally is processed statistically. This significantly universal technique of solving such electrotechnical problems is based on the common mathematical approaches. In this context, it can form the basis for the microprocessor-based electronic diagnostic device.
