Analytical modelling of synchronous reluctance motor including non‐linear magnetic condition

open access: yesIET Electric Power Applications, 2022
This paper presents an analytical modelling technique based on modified winding function and co‐energy analysis, for characterisation of synchronous reluctance machines, in conjunction with a hybrid algorithm for mapping of the machine's operating point ...

Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]

open access: yes, 1996
This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance ...

A Contribution to the Theory of Rotating Electrical Machines

open access: yesIEEE Access, 2021
This contribution introduces a vector interpretation to unify the description of torque development in rotating electrical machines. The motivation behind this attempt is the necessity of applying different physical interpretation and calculation methods,

Cross-Saturation Effects in IPM Motors and Related Impact on Sensorless Control [PDF]

open access: yes, 2006
Permanent-magnet-assisted synchronous reluctance motors are well suited to zero-speed sensorless control because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based ...

Analytical Prototype Functions for Flux Linkage Approximation in Synchronous Machines

open access: yesIEEE Open Journal of the Industrial Electronics Society, 2022
Physically motivated and analytical prototype functions are proposed to approximate the nonlinear flux linkages of nonlinear synchronous machines (SMs) in general; and reluctance synchronous machines (RSMs) and interior permanent magnet synchronous ...

Position-sensorless control of permanent-magnet-assisted synchronous reluctance motor [PDF]

open access: yes, 2003
The sensorless control of permanent-magnet-assisted synchronous reluctance (PMASR) motors is investigated, in order to conjugate the advantages of the sensorless control with full exploitation of the allowed operating area, for a given inverter.
