Update on roller-screw actuator design and applications (with video and image galleries)
Roller screws are also called planetary roller screws or sometimes satellite roller screws for how their nut-encased rollers orbit the drive-shaft axis during operation. These mechanical … [Read More...]
Cannabis cultivation leverages modular automation stations
By Michael G. Giunta • National sales manager | Macron Dynamics Uninitiated laymen might assume today’s cannabis is grown through traditional farming — over horizontal outdoor spaces in natural … [Read More...]
Motion Trends: Applications expand for versatile lead screws
Improvements in lead screw designs have meant screws that are increasingly competitive with other types of drive screws, including ball screws. For instance, lead screws can offer shorter lead times … [Read More...]
New 20-mm linear stepper motor now available from Nippon Pulse
Nippon Pulse now sells the the PFL20 Linearstep — its smallest linear stepper motor yet. The PFL20 is a highly efficient, high thrust tin-can linear actuator with a 20-mm diameter and a bipolar … [Read More...]
Motion Trends: Ball screws pack more load capacity
Continued developments in manufacturing and materials have improved ball screw performance, with the most recent generation of ball screws having greater load densities than ever before, leading to … [Read More...]
What are linear induction motors?
An induction motor is one in which the current in the rotor is induced by the electromagnetic field in the stator, eliminating the use of magnets. A linear induction motor is a type of linear motor … [Read More...]
Are brushed motors suitable for industrial applications?
Brushless motors dominate the industrial motion control market, but brushed motors still make sense for some applications, thanks to their linear performance and ease of use. DC motors can use … [Read More...]
Mechanical properties of materials: Shafts in torsion
Power transmission shafts — on motors and gearboxes, for example — are subjected to torque loads that result in torsion, or twisting of the shaft about its axis. Similar to structures under tension or … [Read More...]
Mechanical properties of materials: Stress and strain
Every component in a linear motion system experiences some form of loading due to applied forces or motion. The component's reactions to these loads are described by its mechanical properties. For … [Read More...]
Application example: Ladders on construction machinery use actuators for better ergonomics
90% of small U.S. construction companies have safety programs, but only a third have programs to improve the ergonomics of workers’ environments. It’s too bad, because the risk of musculoskeletal … [Read More...]
Electric actuators displace other motion options — including manual designs: A Motion Trends report
Today, electric actuators are easier than ever to specify and install. Value-add services from component suppliers as well as application-specific actuator product lines (especially for … [Read More...]
New technologies and applications for linear motors: A Motion Trends report
Depending on the exact technology, typical linear motors can deliver unlimited strokes and (with feedback) accuracies to ±1 μm/100 mm. Speeds range from inches to 1,000s of inches per second. … [Read More...]
Renishaw’s new easy-to-install incremental encoder
Renishaw has launched a new encoder family for linear axes, which offers exceptionally wide installation tolerances and axis speeds of up to 24 meters per second. The QUANTiC encoder series produces a … [Read More...]
Motion Trends: Stages, Cartesian robots, and tables for complete motion designs
New trends in multi-axis motion designs abound. Consider the rise of metrology reports to accompany designs — which serve as “birth certificates” in the form of well-informed simulation models and … [Read More...]
