“…In order to calculate the dimensions of stator and rotor components, it is necessary to first calculate the flux passing through different parts of the motor. The total flux of the motor, the magnetic flux per pole and the magnetic flux per tooth can be calculated as follows: After calculating the magnetic flux in the stator and rotor, the thickness of the permanent magnet can be obtained from following equation [25,26]:…”

“…In addition, these motors when fed by variable frequency supply can achieve higher speeds than PMSMs, so the ratio of the maximum speed to the rated speed in squirrel cage induction motors is estimated to be about three [15]. There are various articles reported in the field of multistack axial flux motors regarding design, construction, optimization, and applications [16,17]. Axial flux motors have special advantages such as a compact structure, proper heat transfer, and more effective usage of active materials, resulting in higher power/torque density [2,11].…”

This article proposes a dual independent rotor axial flux induction motor (DIR-AFIM) with two degrees of freedom as a propulsion motor for an electric vehicle (EV). The performance of this motor in different operating conditions of the vehicle is discussed and investigated. This motor has two rotors that are mechanically independent of each other, providing driving force for the EV separately and enabling the removal of any mechanical or electrical differential. The propulsion motor can play the role of differential and also reduce the cost and complexity of the entire propulsion system in some extent. The finite element modeling of the proposed motor has been performed and the performance characteristics have been evaluated in three operating scenarios: flat path, sloped path, and turning path, taking into account the dynamics of the vehicle. Additionally, the accuracy of the simulations and modeling has been confirmed by performing some practical tests on the prototype machine. The results show that the simulations and measurements are in good agreement and the proposed propulsion system can be a suitable option for lightweight electric vehicles.

A two‐degrees‐of‐freedom (2DOF) dual‐rotor axial‐flux induction motor (2DOF‐DRAFIM) is proposed with independent movement capability of rotors and its performance is evaluated in detail. First, using the analytical equations, the steady‐state model of the motor is presented and the electrical equivalent circuit is extracted along with an electromagnetic design algorithm for the proposed motor. In the next step, using two‐dimensional and three‐dimensional finite element modelling (FEM), the performance of the proposed motor is investigated. The results of the experimental measurements on the manufactured prototype confirm the validity of the results of theoretical modelling and finite element simulations. The proposed structure provides some unique features. One of the fascinating behaviours of the proposed 2DOF‐DRAFIM is that the higher‐speed rotor produces higher output torque and the lower‐speed rotor has lower torque. In this regard, the 2DOF structure can be considered a potential concept for electric vehicles (EVs) without needing a conventional mechanical differential.
