We propose a Kazantzis-Kravaris-Luenberger observer for permanent magnet synchronous motors. We show how the partial differential equation, involved in its design, can be solved explicitly and we suggest a recursive procedure as a solution to the inversion problem involved in its implementation. Simulation results demonstrate the interest of this observer.
