Synchronous Motor with Hybrid Permanent Magnets on the Rotor [PDF]

open access: yesSensors, 2014
Powder metallurgy allows designers of electric motors to implement new magnetic circuit structures. A relatively new concept is the use of a magnet system consisting of various types of magnets on one rotor, for example sintered and bonded magnets. This concept has been applied to the design and manufacture of the four-pole rotor of a synchronous motor

Dynamics and Stability of Permanent‐Magnet Synchronous Motor [PDF]

open access: yesMathematical Problems in Engineering, 2017
The aim of this article is to explore the dynamic characteristics and stability of the permanent‐magnet synchronous motor (PMSM). PMSM equilibrium local stability condition and Hopf  bifurcation condition, pitchfork bifurcation condition, and fold bifurcation condition have been derived by using the Routh‐Hurwitz criterion and the bifurcation theory ...
