Features
The axial circuit has high efficiency and high specific torque. This is due to the cubic dependence of the increase in torque with an increase in diameter, whereas the torque increases quadratically in a machine with a radial magnetic flux.

Electric machines with axial magnetic flux may be used as traction motors for land, air and water transport, as well as in special equipment.
The key feature of the AXD electric motors is high specific power indicators: up to 2.61 kW/kg in nominal operation and up to 6.19 kW/kg in peak operation.
