Stepper motor vs servo motor: Which is right for your application?

04/01/2022

In today’s industrial marketplace, it can be confusing and challenging to choose the correct motor for an application. As well as all the different types of motor, the information provided on each is often either too basic or too technical to be helpful. In this article, Mike Keefe of KEB America explains the differences between stepper and servo motors, and when it is appropriate to use each technology.

Driving for more efficiency

01/12/2021

The optimisation of energy usage by electric motors can lead to environmental benefits, as well as reductions in operational expenses (OPEX). Forward-looking businesses interested in reducing their motors’ energy use can now go further than before, by implementing new tools that enable variable speed drives (VSDs) to save even more energy.

Accurate and stable actuator for an automatic screwdriving application

01/12/2021

Accuracy, repeatability and stability were the key performance requirements specified for an actuator to be used in an automatic screwdriving application for AVK Plastics, a manufacturer of synthetic surface boxes and pallets based in the Netherlands. AVK Plastics turned to HepcoMotion after the previous actuator could not provide the high stability required, causing the company to need a replacement.

Oliver Woolley, ABB HVAC Key Account Manager, discusses the merits of variable speed drives in HVAC applications, and how they stack up against EC fan technology.

Dual AMR motor position sensor for safety-critical applications

01/11/2021

The increased emphasis to improve vehicle safety in recent years has resulted in the welcome advancement and introduction of active advanced driver assistance systems (ADASs) to complement the traditional passive systems reliant on airbag deployment for driver and passenger safety. These emerging systems are intended to initially aid – but, in the longer term, replace – the driver’s vehicle manoeuvre decision-making in safety-critical situations.
