Flux-weakening controlling of AC permanent magnet servo motor
ICEMS'2001. Proceedings of the Fifth International Conference on Electrical Machines and Systems (IEEE Cat. No.01EX501), 2002The paper discusses a method of flux-weakening control for an AC permanent magnet servo motor utilizing d-axes armature reaction. The flux-weakening control idea, control process and its realisation are studied.

Adaptive flux weakening control of permanent magnet synchronous motors
Conference Record of 1998 IEEE Industry Applications Conference. Thirty-Third IAS Annual Meeting (Cat. No.98CH36242), 2002This paper presents an approach for adaptive control of the surface mounted permanent magnet synchronous motor (PMSM) over its entire speed range. This requires coordination of direct and quadrature axis currents i/sub d/, i/sub q/. Direct model reference adaptive control is responsible for the control of quadrature axis current. Direct axis current is

Saliency analysis of PM machines with flux weakening capability
2008 18th International Conference on Electrical Machines, 2008In PM machines, the fixed excitation provided by the magnets limits its suitability for high-speed applications. To correct this deficiency, a variety of designs capable of flux weakening have been proposed. To achieve this feature, a lower amount of magnet is considered as an approach to reduce the flux weakening current requirement.

Design considerations for permanentmagnet synchronousmotors for flux weakening applications
IEE Proceedings - Electric Power Applications, 1998The required parameter values of a permanent magnet synchronous motor designed for very large power-speed range are determined based on a linear dq model. It is shown that unconventional motor constructions with the d-axis inductance equal to, or bigger than, the q-axis inductance can provide superior torque, power factor and control characteristics ...

Mechanical Field Weakening Techniques for an Axial Flux Machine
2019 International Conference on Sustainable Energy Engineering and Application (ICSEEA), 2019The electric machine for automotive applications should have a wide speed range. This paper describes the mechanical techniques to weaken the magnetic field of an axial flux permanent magnet machine in order to increase the machine’s speed range as well as reduce the iron losses. Three different techniques have been simulated and analyzed in this paper

Research on Flux Weakening Speed Control Strategy for PMSM
2017Electronic assisted brake systems require permanent magnet synchronous motor (PMSM) to work in a larger speed range, and to maintain a certain ability to resist load disturbance. In this paper, the mathematical model of PMSM and the flux weakening control theory are analyzed at first.
