Induction Machine: Comparison of Motor and Generator Characteristics

The aim of this paper is to present the difference of induction machine electromechanical characteristics in motor and generator operating modes. Firstly, the paper presents analytically derived equations, which are based on equivalent circuit and are used for calculation of induction machine breakdown torque. Secondly, a comparison of calculated and measured characteristics in motor and generator operating modes is presented. Results of torque characteristics measurements, temperature rise tests and load tests are also provided. Finally the difference between the calculated and the measured results is commented on and explained in detail.
