Interior Permanent Magnet Synchronous Motor Linear Field-Weakening Control
IEEE Transactions on Energy Conversion, 2016At nonlinear field-weakening control of interior permanent magnet synchronous motor (IPMSM), the working point is difficult to calculate and the saturation of current regulators may lead to losing control. Linear field-weakening control (LFC) of IPMSM is proposed to control both torque and current in wide speed range applications and LFC can prevent ...

Optimum-seeking field weakening control of induction motor drives
8th International Conference on Power Electronics and Variable Speed Drives, 2000The optimum-seeking (in the sense of maximisation of torque) field weakening control scheme proposed by Kim and Sul (see IEEE Trans. Ind. Electron., vol. 44, no.4, p.512-18, 1997) is developed further. The performance under imperfect field orientation conditions is investigated, and it is shown that an overestimated-rather than an under-estimated-model

MTPA and Field Weakening Control of Synchronous Reluctance motor
2016 9th International Conference on Electrical and Computer Engineering (ICECE), 2016An improved algorithm for MTPA (Maximum Torque Per Ampere) and Field Weakening operation which is suitable for implementation with Field Oriented Control, has been proposed for the Synchronous Reluctance motor (SynRel) for high dynamic performance. The proposed method overcomes the problem of excessive current flow into the machine while generating the

Microprocessor-based DC motor drive with spillover field weakening
IEEE Transactions on Industrial Electronics, 1991A microprocessor-based speed control scheme for a separately excited DC motor fed from a DC source, which incorporates both armature-voltage control and spillover field weakening to provide smooth and precise control from standstill to speeds well above the base value, is described.

Field Weakening Methods for Axially Displaceable Brushless DC Machines
2018 XIII International Conference on Electrical Machines (ICEM), 2018Brushless DC (BLDC) machines are known to have a high torque/power density but it is still a challenge to design a BLDC with a wide extended speed range while keeping its torque/power density high. A mechanical field weakening method, in which the active axial length of a BLDC machine is reduced on run by axially displacing its rotor with respect to ...
