In this work, complex vector modelling technique is utilized to develop and simulate a dual stator-winding induction machine with squirrel-cage rotor. The transient and dynamic performances of the machine under two cases of input conditions are analysed and presented both at no load and when a ...
which has led to a series of problems, such as wideband oscillations, inertia deficiency, weakened grid strength, etc. To solve these problems, the authors proposed a dual winding induction machine (DWIM)-based generating system. The

Fig. 3. The machine model of OEWIM [26]. 2.3. Open-End Winding Induction Motor Model An OEWIM can be realized physically by avoiding the shorting of stator windings [45]. This facilitates to have six stator terminals namely ‘a1s’, ‘a2s’, ‘b1s’, ‘b2s’, ‘c1s’ and ‘c2s’...
In dual-winding bearingless switched reluctance motors (BSRMs), an additional winding is placed on the stator poles in conventional switched reluctance motors (SRMs), which is mainly to achieve the function of levitation. Due to the hysteresis current control in existing control strategies for dual...

1.A dual-rotor motor comprising:a stator in which a winding is wound around a stator core;an inner rotor disposed at an inner-circumference side of the stator; andan outer rotor disposed at an outer-circumference side of the stator;wherein the inner rotor and the outer rotor are rotatably...
Sensorless FOC Structure of an IPMSM System An IPMSM consists of a three-phase stator winding (a, b, c axes), and permanent magnets (PM) rotor for excitation. The motor is controlled by a standard three-phase inverter. An IPMSM can be modeled by using phase a-b-c quantities. Through ...
