Abstract (en)
[origin: WO2018010032A1] An actuator for high rotational speed applications using a stator which utilizes laminated features to reduce Eddy current losses in the stator. This construction allows high pole counts while providing the efficiency and high speed benefits of a laminated construction. Laminated construction is very challenging for a high pole count lightweight motor, but embodiments of the device provide structural strength, and rigidity, as well as other benefits such as low manufacturing cost, high heat dissipation, integrated cooling channels, and light weight construction. Many of these benefits result from the use of a laminate sandwich of non-magnetic, heat conductive material, such as anodized aluminum, as a structural member of the stator.
