What are the advantages of machined springs?
Abssac explains what advantages machined springs offer over conventional wire wound types.
Bespoke bearings for energy-saving electric drives
Throughout industry, there is a growing focus on the energy efficiency of electrically powered machinery and equipment. The chosen bearings also affect energy consumption. It may prove worthwhile for machine manufacturers and operators to draw on domestic appliance producers’ and carmakers’ experience of using reduced-friction bearings. Tailoring bearings individually to the specific application is the only way to achieve optimum efficiency.
EN ISO 13849-2, validation of safety-related control systems
This article from TUV SUD Product Service explains the requirement to validate the design of the safety related parts of a machine's control system following the recent publication of EN ISO 13849-2.
Explaining the different types of AC electric motor
The myriad motor technologies all have partially overlapping functionalities, so how does an engineer choose the right type of motor for a given application? Jerry Hodek, Technical & Operations Director at Regal, offers this guide for applications requiring precisely metered torque, speed or positioning.
Engineers should no longer oversize motors
Engineers have traditionally oversized electric motors to allow for worst-case operating conditions and to provide an extra margin for 'peace of mind.' However, Stuart Harvey of Softstart UK explains why this is no longer wise, given today's need to reduce energy consumption.
How to calculate point-to-point SCARA movements
Gerard Bush at servo motion specialist INMOCO explains what machine builders need to know about motion control for SCARA robot arms.
Current trends and development projects for wind turbine bearing
Even higher expectations regarding service life and reliability twinned with pressure on costs: this is the picture currently emerging for bearings in the wind energy industry. With the help of examples, the following article explains how one of the world’s leading suppliers develops new generations of bearings in these circumstances.
Servo couplings for a wide variety of applications
Ruland Manufacturing Co., Inc. manufactures a diverse line of servo couplings for applications such as stepper and servo systems, linear actuators, ball screws, lead screws, encoders, and valve actuation. Industries including medical, printing, packaging, machine tools, linear motion, semiconductor, and solar benefit from having a variety of couplings to choose from. Each application has performance requirements that must be met for the system to function properly. Understanding the different characteristics of each coupling is critical when making a selection.
