Drives and motors

Slotless versus slotted brushless DC motors

(28/09/2020)
Brushless DC motors are the technology of choice for applications operating at higher speeds. However two different motor architectures can present a selection conundrum, says Madhavan Ramanujam and Cyril Baud.

Driving towards cost-effective condition monitoring

(01/09/2020)
A new approach to smart condition monitoring allows much more than just monitoring machines and processes – it provides extensive information about the ‘state of health’ of machines and plants without the need for any additional, costly sensor technology, says Marc Vissers.

Servo motor sizing for precision pumping applications

(10/08/2020)
Interestingly, there are some operating conditions where servomotors that should be big enough for an application are actually too small, in terms of their power rating. Find out more.
