How efficient electric motor and pump control is reducing energy use and creating renewable energy

02/03/2023

The ‘drive’ is on to cut energy use, increase efficiencies, and reduce carbon emissions globally. National governments, the United Nations, the European Union and others are all pressing ahead with ever more stringent goals and policies.

Mobility unchained: Fleet start for Schaeffler’s chainless drive for e-cargo bikes

20/02/2023

Electric cargo and utility bikes are becoming an increasingly common sight in big cities, where they are the ideal solution for speedy, climate-friendly transportation and distribution of food, mail, medicine and more. To help with this trend, Schaeffler has been partnering with two-wheeler electric drive specialist Heinzmann GmbH & Co. KG to develop a chainless drive system called Free Drive.

Whether simple or complex: Motor control systems for automation

01/02/2023

Setting up control systems to drive axes is usually time-consuming and can require software programming knowledge. igus has now developed two new cost-effective and easy-to-operate control systems, so that users can quickly start up their motorised drylin E drive axes.

The light we cannot see: Micromotors powering optical technology

20/01/2023

Optics is a branch of science that revolves around light. From cameras and lasers to fibre-optic cables and telescopes, our understanding of the way light behaves and of its properties has enabled its use in a vast array of practical applications. Here, Dave Walsha, Sales Manager at EMS, explains the key role micromotors play in driving a diverse range of optical applications.

How iron losses influence BLDC motor selection

06/01/2023

When designing a miniature brushless DC (BLDC) motor, ensuring a compact footprint, with sufficient thermal regulation, is vital. This means that the design must minimise iron losses, a crucial factor that also limits a motor’s output. Here, Samuel Klein, Application Engineer at Portescap, explains the role of iron losses in BLDC motor design.
