An introduction to feedback devices for VFD and servo applications

An introduction to feedback devices for VFD and servo applications

One issue that often arises when designing closed-loop applications is which type of feedback to use on the motors. In this article, Jeff Kardell of KEB America describes the different types of feedback devices in variable frequency drives (VFDs) and servo applications, as well as some typical examples of where they can be utilised.

New Elesa SFX series hydraulic anti-splash breather caps, plus dipstick

New Elesa SFX series hydraulic anti-splash breather caps, plus dipstick

Elesa now offers a variety of different breather cap solutions to sealing hydraulic tank fillers while enabling air interchange as fluid is drawn from or returned to the hydraulic reservoir. These new caps enable pressure equalisation between the inside and outside of the tank while at the same time using proprietary labyrinth geometry of semi-discs as a major barrier to spillage. This is especially applicable when the equipment is used at variable angles with violent changes of orientation – for example for mobile equipment such as earthmoving-plant, or simply for machines in transit.

Weg supplies motors for world"s largest irrigation project

The quality of agricultural land in India varies from region to region, with some parts being quite arid. In fact, in parts of the country where land requires water levels of up to 800m, just 200m of water is present. Without water facilities nearby, these low water levels are not sufficient to irrigate this dry agricultural land. Here’s how industrial motor manufacturer Weg has partnered with MEIL to provide equipment for the Kaleshwaram lift irrigation scheme, a multi-purpose irrigation project on the Godavari River in Kaleshwaram, Telangana, India.
