Purpose Modeling electric machines is one of the powerful approaches for analyzing their performance. A dynamic model and a steady-state model are introduced for each electric machine. Permanent magnet induction machine (PMIM) is a dual-rotor electric machine, which has various advantages such as high-power factor and low magnetizing current. Studying PMIM and its modeling might be valuable. The purpose of this paper is to introduce a simple and accurate method for dynamic and steady-state modeling of PMIM. Design/methodology/approach In this paper, arbitrary dqo reference frame is used to model PMIM. First, three-phase dynamic equations of stator and rotors are introduced. Then, they are transferred to an arbitrary reference frame. The voltage and magnetic flux equations aligned at dqo axes are obtained. These equations give the dynamic model. To investigate the results, PMIM simulation is performed according to obtained dynamic equations. Simulation results verify the analytic calculations. Findings In this paper, dynamic equations of PMIM are obtained. These equations are used to determine dynamic equivalent circuits of PMIM. Steady-state equations and one phase equivalent circuit of the PMIM using phasor relations are also extracted. Originality/value PMIM equations along dqo axes and their dynamic and steady-state equivalent circuits are determined. These equations and the equivalent circuits can be transformed to different reference frames and analyzed easily.

“…Several kind of dual rotor motors of this sort have been reported in recent literatures, such as: (i) double-sided slotted axial flux motor having two outer permanent magnet rotors and one inner winding stator [11,12]; (ii) dual rotor motor consisting of an outer stator, inner wound rotor and outer permanent magnet rotor [13]; (ii) dual rotor motor consisting of double stator as well as double rotor for electric moving vehicle that structurally seems to be two independent motors integrated into one [9]; (iii) dual rotor motor consisting of one inner and one outer permanent magnet rotors and one winding stator at the centre [10]; (iv) dual rotor motor consisting of one inner and one outer permanent magnet rotor and one toroidally wound stator at the centre [14], and the like. There are also literatures on dual rotor induction motor [15,16].…”

Conventional electromagnetic motor contains two components -stator and rotor. In this present case, both the components of an electromagnetic motor are allowed to remain free, i.e. both the components are allowed to rotate. Thus, there is no stationary stator in the mechanism. The mechanical output of the two counter rotating shafts is collected through a common transmission shaft via either gear mechanism or a combination of gear and belt mechanism. Although dual rotor counter rotating motor has been recently disclosed in an US Patent, the present one is an innovation designed to trap the maximum potentiality of such an electric motor. Depending upon the type and size of the motor, there will be a net increase in energy efficiency in between 25 to 125 per cent over their respective conventional variants. This has huge implication in the field of electrical power generation and consumption.
