eVTOL Motor Core

Huaci provides high-performance motor cores for eVTOL aircraft components, meeting their demands for high power density, high torque, and compact design.

eVTOL Air Mobility

In the rapidly evolving world of urban air mobility, the design of a high-performance evtol motor core is pivotal for powering the next generation of electric aircraft. Engineers face challenges in achieving optimal efficiency, thermal management, and weight reduction in motor cores.

eVTOL propulsion systems demand an optimized motor design that minimizes weight while delivering high power density and efficiency. In a bonded lamination motor core design for eVTOL, every gram saved translates directly to improved range and payload capacity.

1J22(Hiperco50, Permendur, 49КФ, AFK502, SME SMEV)

Advancing the efficiency of eVTOL motors hinges on innovative materials and manufacturing methods. Advanced bonded motor cores for electric aircraft are emerging as a solution, using high-permeability alloys and precision bonding in stator core assembly to minimize eddy current losses. Automated lamination stacking—ensures uniformity and structural integrity.

1J22 is a specialty soft magnetic alloy with high power density and low coercivity.

Compared to traditional electrical steel, 1J22 offers nearly 25% higher magnetic induction and 30% lower losses, enabling maximum torque density while minimizing losses in motors and generators. Motors made with our high-performance stators and rotors can achieve a 20% to 30% increase in power density and significantly reduce weight.
