Copyright © 2012 - 2018 Limited Angle Torque Motors (LATs) or Rotary Switches are ideal for high-response precision control systems with limited angular range. Avior provides LATs housed or frameless in simplex or redundant configurations.
Cog-less and Conventional Frameless Motors are ideal for precision direct-drive applications where large through bore must be maximized, torque ripple disturbances must be minimized or drive configuration does not allow for geared actuators. 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., Inc. All rights reserved.
Housed Brushless DC Motors are much more efficient and capable of driving high load inertias, when compared to Stepper Motor Actuators. These motors have tremendous mechanical power output capacity and high efficiency. Frame sizes up to 3.0” (76mm) and power output to 4 kWatts are currently available. Avior’s “True-Trap” back emf provides low torque ripple, even with trapezoidal commutation.

While critical internal dimensions are standardized, Avior provides custom mounting interfaces and output shaft configurations, tailored to specific application requirements.
Additionally, Avior may custom design a motor using the same materials, processes and exacting standards that we have proven in our standard modular designs.
