Avoiding installation issues with PWM inverters Variable speed AC drives have become very popular because of their energy efficiency. Additionally, they offer flexible control of processes and machinery using maintenance-free AC motors. AC drives use power switching techniques and generate high rates of change of voltage. Most modern AC drives use voltage-source PWM inverters. […]
Modern VSDs use sophisticated electronics for control and communication. They will operate in extreme conditions and are very reliable and effective. However avoiding inverter drive failures involves regular review and maintenance. Despite being serviceable, drives are often forgotten after installation. Recognising this, manufacturers have made developments to improve their reliability. They invest significant time […]
Energy savings? I don’t believe it. Sometimes, the simplest solutions are the best. UK manufacturing needs to improve its productivity. An easy way of achieving this is to reduce energy costs. At least, so you would think. Yet, a report from ABB suggest theory and practice are not the same when it concerns reducing […]
The reliability of electrical and electronic equipment is critical to most production plants. Heat induced equipment failures causes damage to expensive equipment, and loss of production due to downtime. Electrical equipment life is extended by operating at the correct cabinet temperature The temperature inside an electrical cabinet is invariable higher than the ambient. The […]
With energy prices again starting to rise, now is a good opportunity to review some of the financial incentives from the UK Government for installing energy saving equipment. For example, it is not only the ECA scheme that makes installing energy saving as variable speed drives sound investment. In addition to lower running costs, […]
