1. 1. Real-Time Rotor Temperature Estimation Method for Interior Permanent Magnet Synchronous Machines : A method using a Lumped Parameter Thermal Network in combination with an estimation algorithm: implementation and comparison of a Dual Kalman Filter and a Dual Observer

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Elvira Niemelä; [2022]
   Keywords : Permanent Magnet Synchronous Machine; Permanent Magnet Temperature Estimation; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer; Permanentmagnetiserad Synkronmaskin; Temperaturestimering för Permanentmagneter; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer;

   Abstract : Accurate knowledge of the temperature of a Permanent Magnet Synchronous Machine is of high importance, not only to ensure safe operation and improve control of the operating point, but also to avoid irreversible demagnetization of rare-earth permanent magnets. However, direct measurement using thermal sensors is not suitable for high volume and low-cost applications, due to costly sensor installation and maintenance, and therefore, the magnet temperature needs instead to be estimated.

   Abstract : The permanent magnet synchronous motor, PMSM, is an efficient electrical motor that has seen a greater prevalence in the automotive industry from the increasing demand for electrical vehicles. Managing the temperature of the permanent magnet rotor is important to optimize motor utilization and avoid hardware failures. READ MORE

4. 3. Online parameter estimation in electric motors

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Abizar Sadikot; [2021]
   Keywords : Technology and Engineering;

   Abstract : The permanent magnet synchronous machine (PMSM) can be used for a wide range of applications. In this case, the motor that is examined is inspired of Husqvarna's handheld electrical tools where the motor is part of its electrical chainsaw. The idea is to investigate and simulate different algorithms for online parameter estimation for the PMSM. READ MORE

5. 4. Parameter Estimation in a Permanent Magnet Synchronous Motor

   University essay from Reglerteknik

   Author : Mikael Tenerz; [2011]
   Keywords : Permanet magnet synchronous motor parameter estimation;

   Abstract : This thesis adresses the problem of estimating the parameters in a permanent magnet synchronous motor (PMSM). There is an uncertainty about the parameters, due to age and tolerances in the manufacturing process. Parameters such as the resistance and the current to torque factor Kt, changes with respect to temperature as well. READ MORE
