Limited Angle Torque Motors are Precise Reliable, and Compact

Valencia, CA-Applications for Limited Angle Torque Motors (LAT) from H2W Technologies can be found in the depths of "Inner Space," to the far reaches of "Outer Space." Commonly referred to as "Torquers," these rotary actuators are ideal for applications that require quick, precise angular positioning (typically less than 170°). High acceleration (to 10,000 rad/sec²), high accuracy (to 1 arc/sec), and high repeatability (to 0.5 arc/sec) make them ideal for: Focusing lenses, positioning laser reflecting mirrors, operating valves, machine tools, and clean-room and aerospace applications.

Kit style and housed torquers are available in a broad range of sizes and custom designs. Models featuring a continuous torque rating of 500 oz-in (3.5 Nm) and a peak torque rating of 1500 oz-in (10.5 Nm) are available. They easily fit in spaces where conventional motors will not. The kit style TMR-V series of LAT motors has been designed for extreme applications and is well suited for closed loop applications requiring a compact device that provides smooth, torque ripple free movement. The TMR-H series of motors are housed. The shaft of the "H" series LAT motor can be custom configured and it extends out of the back for mounting an encoder. Custom front and rear mountings are available.

Extremely smooth in operation, and vacuum compatible to 10-5 Torr, these single phase, non-commutated LAT motors offer an excellent linear torque profile (constant torque) for the rated angular displacement, resulting in easier setup and tuning of the control loop.
