Field Oriented Control of IPM Drives for Flux Weakening Applications [PDF]
EPE Journal, 2010 Interior Permanent Magnet (IPM) drives are adapted to flux-weakening, then to constant power operation over a wide speed range. Most of the control strategies for IPM motor drives are based on the control of the current vector. Flux-weakening is obtained by proper current references, that are calculated according to the magnetic model of the motor ...

Permanent Magnet Rotor Flux Linkage Control Through Direct Axis Field Amplification
IEEE Open Journal of Industry ApplicationsPermanent magnets are popular for electric vehicle rotors due to their high energy density, making them excellent candidates for high-torque and high-speed machines. The downside of a permanent magnet machine is the inability to regulate the rotor field,

The realization of a permanent magnet synchronous motor drive with flux weakening [PDF]
Modeling, Identification and Control, 1992 This paper presents the realization and performance of a fully digital permanent magnet synchronous motor drive. A new control algorithm gives maximum torque to current ratio in both the constant torque region and in flux weakening.

Reducing iron loss in interior PM machines under field-weakening conditions [PDF]
, 2007 Field-weakening in interior PM machines is performed by using negative rf-axis current to oppose the magnet flux and hence reduce the total fundamental rf-axis flux at high speeds.

Turbulent drag reduction in magnetohydrodynamic and quasi-static magnetohydrodynamic turbulence
, 2020 In hydrodynamic turbulence, the kinetic energy injected at large scales cascades to the inertial range, leading to a constant kinetic energy flux. In contrast, in magnetohydrodynamic (MHD) turbulence, a fraction of kinetic energy is transferred to the ...
