Space Rated Cog-less and Conventional Direct Drive Motors are ideal for precision applications where large through bore must be maximized, torque ripple disturbances must be minimized or the drive configuration does not allow for a geared actuator. These motors offer smooth performance, sinusoidal back emf with low harmonic distortion, high torque capacity, and are available in sizes up to 10” in diameter (255 mm). Conventional Motors offer higher efficiency and lower cost, compared to the Cog-less alternative. Options include titanium or special material mounting flanges, potted (encapsulated) windings and custom mounting interfaces. Avior’s proprietary techniques of winding lay-in and material selections allow for higher efficiencies (motor constant) per unit volume than competitors designs.
