Hybrid Stepper Actuators are electromechanical devices that incorporate a rotary hybrid stepper motor with a rotary-to-linear device (typically a Lead Screw) to impart motion to linear axes. Adopted in the 1980’s, hybrid stepper motors excel in compact machines requiring simplicity. Pre-integrated hybrid stepper actuators take the ease of application further to allow design engineers to preconfigure subsystems to actual stroke, speed and force requirements.

AMETEK Dynamic Fluid Solutions (DFS) and HVAC and boiler manufacturer Mestek Inc. have partnered for years on blowers destined for integration into various boiler products and subsystems. This white paper showcases the benefits of their design partnership.
Bypass blowers are electric-motor-driven blowers that segregate two paths of air:
Some motion applications need axes to deliver both linear and rotary motion. Conventional designs for such functionality are often complicated and bulky. What’s more, rotary motors put to linear motion often have output shafts that are inadequate for supporting heavy side loads.
Brushed dc and brushless dc motors must be compatible with and satisfy critical motion-system parameters. These include the application voltage supply, overall footprint, target design life, continuous speed, and continuous torque requirements.
Leadscrews — especially those with high-accuracy threads — can be a low-vibration alternative to other linear-motion options. That’s in part because of the consistent contact between their load-bearing mating subcomponents.
This white paper will discuss methods of selecting the best Stepper Drive for motion control applications requiring a Stepper Motor or a Stepper-Based Linear Actuator; information about the typical types of Drives; effects of different applied voltage levels; and of various Drive settings / options for operation.
Incremental encoders are used on motors and equipment as feedback devices to determine position and direction of machinery. Motor controllers can also use position information from the encoder to commutate the motor and calculate velocity for speed control. The incremental encoder is a critical component that provides important data necessary for the precise control of a variety of motion systems. This paper describes the output of a typical incremental encoder.
In many devices lead screw assemblies are used to convert motion from rotary to linear and vice versa. Historically these assemblies have had poor efficiencies and relied on grease for improved performance. Over the past few decades the advent of engineered polymers and new manufacturing capabilities have changed the game for the conventional lead screw assembly making it a powerful solution for motion based design challenges. At first glance lead screw assemblies seem rudimentary, but they are designed to perform a very specific function, and even with the latest developments in materials and manufacturing processes having a basic understanding of how lead screws operate can be the difference between a successful design and catastrophic failure.
Traditionally, reflective encoders have been considered a lower end option used when cost was more important than options. Whether needing high CPR, an index channel or compact sizes, it’s time to reevaluate reflective technology. New encoders are still economical but now offer improved performance with the availability of many output configurations.
