The state of the art of high-torque electric motors has been reviewed in this paper. This paper presents a literature review of high-torque density electric machines based on their airgap classifications, which brings a unique consideration to new design ideas to increase torque density. Electric machines are classified into three main groups based on their airgap configuration, i.e., (1) machines with a constant airgap, (2) machines with a variable airgap, and (3) machines with an eccentric airgap. This paper also presents the modeling of a high-torque airgap-less electric motor based on the concept of eccentric airgap. The torque density of this motor has been compared to motors available in the literature review. Among electrical motors with no permanent-magnet, airgap-less electric motors take the lead in terms of torque density, which is almost five times greater than the next motor, “in-wheel for electric vehicle”.

Internal Permanent Magnet brushless DC motor is one of the various types of electric motors using permanent magnets that are inserted into the rotor's core without having to stick it like a permanent magnet motor mounted on the surface.This motor has better torque characteristics, high efficiency, and sturdy construction. But the consequences in the use of permanent magnets can’t be separated from the interaction between the permanent magnetic field mounted by the rotor with stator teeth. So that development is needed to obtain the results of better cogging torque and efficiency, such as variations in the external rotor IPM-V angular range of 80 °, 90 ° and 100 ° in 18 slots and 16 pole models which are simulated using the Infolytica Magnet application based on Finite Element Method (FEM), the data is processed using Microsoft Excel, so that the output will be a parameter in the Simulink MATLAB 2016a modeling to get the characteristics of the design motor. Variation testing on the motor is done at a speed of 2100 rpm. The results of the test show that the minimum cogging torque value in the angle model of the 90 ° magnetic range is 1.64 Nm with the highest efficiency of 80.6%. Smaller cogging torque values will reduce vibration or noise when the motor is spinning. The high value of efficiency indicates the losses that cause heating on the motor are smaller, so that the motor operating period becomes longer.

“…The application of PM in the motor can be categorized into Surface-Mounted PM Motor (SPM), Interior PM Motor (IPM), Flux-Switching Motor (FSPM), and Hybrid-Excitation Flux-Switching Motor (HEFSM) [6,7]. Based on the application of PM, it can be incorporated inside or on the surface of the rotating structure [8,9]. IPM and SPM have been commonly used in industrial and domestic appliances due to their high efficiency of 80-93% with a wide power range against speed range, and have been explicitly associated with electric vehicles for their traction appliances [10].…”

Conventional motors have the advantage of robustness, high torque output capability, and power performance compared to modular motors. However, traditional motor structure inhibits fault tolerance. For that reason, this paper proposes the structure of a modular stator. It focuses on the performance of modular stator outer rotor flux switching permanent magnet motor (MSOR-FSPM) and Segmental Stator Hybrid Excitation Switched Reluctance Motor (SS-HESRM) by simulation using 2D-FEA in no-load and load conditions. Based on the results, the maximum flux linkage of MSOR-FSPM is 0.02 Wb and 0.05 Wb for SS-HESRM. The average torque output for MSOR-FSPM at maximum armature density is 108.43 Nm and 45.26 Nm for SS-HESRM. Therefore, the torque density for MSOR-FSPM and SS-HESRM is 3.78 Nm/kg and 10.63 Nm/kg, respectively. As for the conclusion, a modular stator motor is capable of inherent fault tolerance compared to a conventional motor structure. Moreover, a modular stator motor produces a higher torque and power density because of the low iron core and optimum flux linkage.
