“…In the mean time Ferrite -PMassisted RelSyn [70][71] switched reluctance [72], DC excited SM (with contactless power transfer to the rotors [73]) have been tested up to 100 kW for HEVs and EVs with competitive performance per cost. Multiphase motor configurations of the above machines for higher fault tolerance or even PMless BLDC multiphase reluctance machine [74], controlled like DC brush machines, stator PM tooth-wound coil PM machines, Vernier PM machines etc. have also been investigated lately for HEVs and EVs.…”

Starting with Faraday's law of electromagnetic induction in 1831, electric (electromagnetic) machines have been developed ever since as "assembles" of electric and magnetic coupled circuits that convert mechanical to electrical energy (in generators) and vice versa (in motors), via magnetic energy storage. Generators and motors are reversible. The Maxwell four equations (laws) later in 19th Century have prompted the rapid development of all basic (DC. brush and travelling field AC machines by 1900. Then by 1930 AC (alternating current) power (energy) systems evolved by connecting in parallel electric synchronous generators (with voltage boost and buck electric transformers for efficient AC power transmission lines) of rather constant frequency and voltage, driven by turbines (prime movers) that harness fossil (coal, gas or nuclear fuels), thermal or hydro energy. The last 50 years have witnessed a dramatic extension of generators power/unit, renewable energy generators and of variable speed AC motor drives in applications with variable output such as ventilators, pumps compressors, conveyors, orrmills, electric transport (mobility), industrial automation, robotics, home appliances and infogadgets. This formidable development, required by the need of more but cleaner energy, was mainly driven by power electronics, better materials, better modeling, design methodologies and digital control. This humble inaugural overview attempts to combine a brief history of electrical generators and motors with recent progress and trends in their design and control, for representative applications.

“…Active flux has been defined in the literature [24–29] as

ψ_{ext} = ψ_{normalr} + false(L_{d} - L_{q} false) i_{d}

where

ψ_{ext}

represents the active flux, which is a sum of two terms – the conventional permanent‐magnet flux linkage and a flux linkage due to saliency [25]. This active flux is the fictitious permanent‐magnet flux linkage of an IPMSM.…”

“…The estimated speed and stator resistance are then imputed to the active flux SMO. The ‘active flux’ concept [24–29] provides alternatives to convert the model of IPMSM into an equivalent model of SPMSM. The active flux SMO is designed with sigmoid function to estimate the active flux and calculate the torque in the α – β reference frame.…”

To achieve high-performance sensorless control of permanent magnet motors with non-sinusoidal back electromotive force (EMF), an improved sliding mode observer (SMO) adopting synchronous rotating low-pass filter (SRLPF) is proposed. The SRLPF is utilised to reduce the back-EMF harmonics and extract the fundamental component. Different from the traditional rotor position observer, the proposed observer can calculate the rotor position with the back-EMF fundamental component. Owing to the decrease in the influence of non-sinusoidal back-EMF, the estimated rotor position harmonic ripple error can be greatly reduced. Then, the high estimated accuracy and excellent sensorless control performance can be obtained. In addition, the proposed strategy is easy for implementation. With the comparison between the traditional SMO and the proposed observer, the experiments of the system steady-state error, the speed tracking performance, and the disturbance rejection ability in the speed range from 60 r/min to the rated speed 750 r/min are presented. The validity of the proposed method is conformed.
