Inefficient heat dissipation in high-power density electric motors leads to insulation degradation and power loss. Improved cooling prevents thermal failure and increases continuous power output.

High rotational speeds cause mechanical stress and deformation in laminated rotor stacks. Preventing structural failure ensures high-speed operational integrity and motor longevity.

Excessive heat accumulation within the rotor and excitation components leads to insulation failure and reduced power density. Mitigating this thermal bottleneck prevents component degradation and allows for higher continuous torque output.

High-speed rotation causes mechanical stress and physical distortion of the laminated stack. Preventing structural failure or shifting under load ensures motor integrity and efficiency.
