Cog-less and Conventional Direct Drive Motors are ideal for precision applications where large through bore must be maximized and available configurations cannot accommodate housed or geared actuators.  Avior may provide trapezoidal or sinusoidal back-emf, depending on the control system requirements.  Avior has a proprietary winding lay-in that provides higher motor constant per unit frame size, compared to competitors’ offerings for trapezoidal applications. Alternatively, we may offer Cog-less Direct Drive Motors with low harmonic distortion sinusoidal back emf for the ultimate in smooth control at low velocities.
