“…Induction machines are categorized into two categories-induction machine with squirrel cage rotor, and induction machine with wound rotor. Induction machines with a squirrel cage rotor operate as the voltage is induced in the rotor windings that will produce the rotor current and magnetic field [45][46][47][48]. Another type of induction machine is the wound rotor induction machine where the rotor has a three-phase winding inside it.…”

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”.
