The review is performed by using well-defined performance criteria with a direction to identify the exemplary and potential applications. In addition to this, initial guidelines to compare the performance and applicability of these novel actuators are provided. The meta-analysis is restricted to five main types of actuators: shape memory alloys (SMAs), fluidic elastomer actuators (FEAs), shape morphing polymers (SMPs), dielectric electro-activated polymers (DEAPs), and magnetic/electro-magnetic actuators (E/MAs). In exploring and comparing the capabilities of these actuators, the focus was on eight different aspects: compliance, topology-geometry, scalability-complexity, energy efficiency, operation range, modality, controllability, and technological readiness level (TRL). The overview presented here provides a state-of-the-art summary of the advancements and can help researchers to select the most convenient soft actuators using the comprehensive comparison of the suggested quantitative and qualitative criteria. Keywords: soft-robotics; actuator performance; SMA; SMP; FEA; DEAP; E/MA 1.

  • Comparing Traditional and Integrated Rod-Style Linear Actuators
    How roller-screw and ball-screw actuators compare in high-force applications: As electric rod-style actuators overtake fluid power in a variety of high-force applications, it is important to understand how different screw technologies compare in the search for optimum performance and low life-cycle cost. Electric rod-style screw actuators are replacing fluid power in high-force applications throughout industry. Tasks once limited to hydraulic and pneumatic cylinders such as pressing, holding, lifting and spot welding are now being performed by electric actuators that offer lower life-cycle costs. Hydraulic and pneumatic cylinders still have their place, but electric actuators have numerous performance advantages in high-force applications up to and exceeding 50,000 lbf. Some of these advantages include a smaller footprint; a long and more predictable life; lower life-cycle costs; greater accuracy, control and flexibility; lower maintenance; faster change-over and setup; lower energy use; and less environmental impact. In general, screw mechanisms provide the means to produce linear motion by the rotation of either the screw or nut in an assembly. The screw is a cylindrical element that has threads; the nut is a matching component that rides on the screw. Each component is capable of rotating independently upon the other. Linear motion occurs by restraining one element. Tolomatic is a leading supplier of electric linear actuators. Tolomatic’s In high-force applications, two types of screw technologies are typically used in electric 60+ years of expertise covers a wide rod-style actuators: ball screws and roller screws. Actuators with ball screws and roller range of industries and linear motion screws are now able to achieve extremely high forces, making them suitable for many applications.

    How to Choose the Best Linear Actuator for your Application Jump to Section: General Actuator Comparisons March 20, 2020 Price Range Velocity Range Acceleration Range Moving Load Range Accuracy Repeatability Travel Distance Ball Screws Lead Screws Rack and Pinions Moving Timing Belts Fixed Belts Advice for All Actuators Summary Lead Screw [SDP/SI], Rack and Pinion [QTC Gears], Ball Screw [Reliance Automation], Fixed Belt [Bell-Everman] There is a wide array of actuators available and there are volumes written about every type. However, there’s not much information comparing dierent types of actuators in real-world settings. So, how do you choose the best type of actuator for your application? Should you use a belt or a lead screw? A rack and pinion or a ball screw? A fixed or moving motor? If you’re building your own actuator, which types are the easiest to manufacture? Which systems are the most (and least) robust? Every day, Teknic’s servo systems power hundreds of thousands of actuators. We don’t build actuators, but, for our customers to be successful, their actuators must perform well and reliably. For the past thirty years, Teknic has worked alongside our OEM customers, helping them select and design mechanical systems to optimize their machines’ motion performance. We’ve learned quite a bit over the years and we’d like to share that knowledge with the general public. General Comparisons Between Actuator Types If all machines had the same motion requirements, there’d be one type of actuator—but there are many dierent machines with various requirements.
