VSDs vs EC fans

01/12/2021

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.

Variable speed drives for safer operations

04/10/2021

Functional safety is more important than ever as production systems and processes become more sophisticated. When building safety systems, variable speed drives (VSDs) can be integrated into systems to ensure that standards are met, and performance level is improved.

Running a brushed DC motor as a generator

07/09/2021

It won’t surprise engineers with even a fundamental understanding of motor design that a brushed DC motor can be operated as a generator to produce a DC power supply. However, it is possible that they will not yet have appreciated the usefulness of the principle, considering the increasing number of intelligent, remote, powered devices.

Can DC motors be used at high temperatures?
