How to correctly set up a VSD?

A Variable Speed Drive controls motor speed and torque by varying the motor input voltage and frequency. A very close match between motor speed and the output requirements of the machine it is driving may therefore be achieved. Variable Speed Drives offer the user a number of advantages including: Energy savings Elimination of expensive mechanical …

Power failure: What does a drive do when power dips?

Public electricity supplies are generally reliable, but they do suffer disturbances. Obviously a total loss of supply results in all electrical equipment stopping, unless it has a backup supply such as a UPS and/or backup generator connected. When the power returns the equipment re-starts from the off state in the way it was designed to …

How can I calculate energy efficiency savings for drives?

Electric motor driven systems comprise a massive 40% of the world’s total electricity consumption, and 65% here in the UK. But many businesses are unaware of the technologies available to them which have the potential to significantly reduce their energy costs, and in turn the global and UK demand for electricity by a staggering 20% …

Four-core cables – Why these should be avoided in drive installations?

Many installers prefer using four-core cable, as this is the traditional way for many installations and also because it provides an element of convenience, with the earth lead already included within the cable sheath. However, when earthing a drive system, two aspects need to be considered – personal protection and EMC. The protective earth exists …

3 Easy Steps to stop Bearing Current Failures with Drives

How to deal with persistent bearing currents On rare occasions, operators in the process industry may note that their low voltage motors experience a current flowing through the motor bearings, especially when they are used with a variable speed drive (VSD). Left unchecked, these bearing currents will inevitably result in premature failure. Two new approaches can eliminate …

Why you must use Variable Speed Drives in pumping applications!

Variable speed drives in pumping applications Pumping applications represent a significant opportunity for applying variable speed drives (VSDs) in new, as well as retrofit installations. The majority of pumping applications need to be controlled. It is unlikely that a pump will run continuously at a maximum speed.     Many analyses show that energy consumption is …
