101 frequencies, yet for most grades of electrical steel laminations, higher frequencies cause higher losses. The conflicting properties of electric steels and newer ESCs bear close study in order to determine an optimal alternative to the most severely affected laminations. That may be to remove the steel core entirely, or to use a different thickness or alloy of the steel. Conclusion The arrival of these new electric motor designs and recent advances has come at a critical time for the industry. With customers forever asking for more data, speed, range, options and so on from unmanned systems services, it is vital that better electric motors are available and that motor controllers, batteries and NVH engineering are improving as well.
