[Lesics] has a good overview of axial flux motors. From the above analysis, it can be found that the research study on improving the torque density mainly focusses on the three-phase PMSM, but there are few studies on the six-phase PMSM with toroidal winding. A closer look at axial flux motors. Axial flux motor is ideal for high torque density and space-constrained applications. Current, therefore, runs radially, from the center of the motor to the outer edges, and torque is produced around the axis of the motor, according to the principle of the Lorentz force. Our motors make big power by spinning very fast, and having very high surface to volume ratio for power dissipation, and burst loads. Home E-MOTORS 348 (380kW | 1000Nm) Share EMRAX 348 *Subject to drive cycle, thermal conditions and controller capability. More specifically I read it to be called the lever concept. Usually, the impetus for using an axial flux motor is the ease of construction, but with the right design, they . Like radial flux motors, they can be designed to work at low voltage (48V) for scooters and small city EVs or, in the future, autonomous pods, as well as at high voltage for any kind of EV up to. One of the reason is that it has larger diameter. The torque is determined by d2/l, where d is the airgap diameter and l is the length, so designs tend to focus on increasing the diameter before increasing the length. The uniqueness of the engines lies in the extremely fast adaptation to the customer's needs. Posted May 19, 2021 by Jeffrey Jenkins & filed under Features, . The YASA 750 R is an axial-flux electric motor with high torque and power densities. . I can't get the motor I found on the web until next year.
