Turntide’s axial fl ux motor: Compact, powerful and driving the zero-emissions future
Driving the future of transport with axial fl ux motor technology AXIALFLUX T
he drive for eff icient, compact, and sustainable transportation solutions is steering the world toward
innovative motor technologies. One such innovation at the forefront is the axial fl ux motor. Often hailed as the next big thing in electric vehicle propulsion, the axial fl ux motor is set to redefi ne the industry.
WHAT’S AN AXIAL FLUX MOTOR? While most are familiar with the traditional radial fl ux motors where the magnetic fl ux runs radially, from

the motor’s centre outward, the axial fl ux motor takes a diff erent approach. Here, the magnetic fl ux operates along the motor’s axis. This change, while seemingly subtle, brings a suite of benefi ts to the table.
DESIGN AND BENEFITS Axial fl ux permanent magnet machines redefi ne motor performance. They typically off er more torque for a given motor volume, thanks to the active magnetic surface area being on the face of the rotor as opposed to the exterior diameter, inherent to radial motors. Consequently,
axial fl ux motors are considerably more compact. Their axial length is drastically shorter than radial machines, an aspect vital for applications like in-wheel motors. This compactness doesn’t sacrifi ce power; these motors boast a higher power and torque density than their radial counterparts, and they achieve this without needing to operate at extremely high speeds. Their eff iciency is another standout
feature. Boasting eff iciencies often exceeding 96%, they benefi t from the shorter, one-dimensional fl ux path, which rivals or even surpasses
