Linear Actuators

HSI offers a complete family of linear motors. The HSI line of linear actuators provides both a broader range and, for a given size, significantly higher thrust than previously available from mini-steppers. Five basic frame sizes arc available, 15 mm, Q 20 mm, Q 26 mm, + 36 mm, and Q 46 mm. The motors incorporate a threaded rotor in conjunction with a (leadscrew) shaft to provide rapid linear movement in two directions (inward and outward). Available step increments vary with the motor frame sizes and are dependent on the basic step angle of the motor and the lead screw pitch. A captive or non-captive shaft (leadscrew) option can be supplied for every size except Q 15 mm motor which is available with. a captive shaft only. The captive shaft configuration features a built-in anti-rotation design. The non-captive shaft option requires the customer to provide external antirotation. Both unipolar and bipolar coil configurations are available. HSI&8217;s patented design accepts a larger rotor than conventional units, improving efficiency and eliminating the need for massive heat sinks. Unique HSI features impart ruggedness and reliability that assure long life and consistent performance. Rare earth magnets are available for even higher thrust. All units are built with dual ball bearings for greater motion control, precise step accuracy and long life. Applications include medical instrumentation, office equipment, machinery automation, robotics, sophisticated pumping systems and other automated devices which require precise remote controlled linear movement in a broad range of temperature environments.
