Abstract

Resistance (equivalent circuit parameters) of the induction motor (BP), defined in this paper, compared to their base (project) values ​​that are found by the electromagnetic analysis [1, 2]. The article [3] first performed an analysis of the algorithm for calculating the resistance of blood pressure, which is obtained on the recommendations of the Guidelines [4], and on the basis of the analysis drawn up its own algorithm. Then, by the settlement of both algorithms in [3] is given the following recommendation: In the case of determining the short-circuit current (SCC) AD resistance should be calculated according to the algorithm, which is obtained on the recommendations of [4], and in the case of determining the performance - according to the algorithm proposed at [3]. However, experience of using the paper [3] recommendations showed that in some cases, a finding of resistance to these recommendations BP inadequately defined some loss components - for example, iron loss. Therefore, in this paper we propose a new algorithm for the calculation of which the fault is excluded. As it is also possible to define all kinds of components and loss of blood pressure with little resistance sufficient approximation to the basic values ​​found on [1]. Calculated using them the performance of BP is almost identical to the basic performance characteristics given in [1]. The proposed algorithm has been tested in this article on the example of the five pairs of blood pressure with the cage and slip-ring motors with a wide spread source (catalog) database. In connection with the above, this algorithm is recommended for further practical application in case of blood pressure calculation performance by catalog data.
