1. 21. Dynamic Braking: A new Approach for Testing Electrical Machines.

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Eloy Pedro Sánchez Caton; [2012]
   Keywords : Technology and Engineering;

   Abstract : In this thesis, a novel method for characterizing Permanent Magnet Synchronous Machines(PMSMs) based in the dynamic response of the analyzed motor is evaluated. The most significant motor characteristics -torque, flux and efficiency maps- are computed from the motor voltage, currents and rotor position data sampled during the experiment. READ MORE
