Rapid Growth Of Renewable Energy

Renewable energy production and use has grown at an overwhelming rate – the acceptance and uptake of this technology has been greater than anticipated with countries continuing to set target dates for converting to 100% renewable energy [1]. At least 30 countries generate more than 20% of their energy from renewables, and 120 countries have […]

RFL’s Unique Design is Proving Extremely Valuable

By the end of 2015, 23.7% of energy was delivered from renewable sources with 3.7% of the total worldwide electricity supplied by wind energy, which is growing at a rapid rate of 17% per annum. Since 2011, the cost of wind generating infrastructure has fallen by 10%, making wind energy 14% cheaper than new coal […]

PMSG technology supports the Army’s complex power requirements

The array of electrically powered systems used in the military has expanded beyond anticipation over the past decade and is continuing to grow at an unprecedented rate. Unfortunately, deployed power systems have not been upgraded to meet power requirements.  The Army has an extremely rapid, mobile, spontaneous and agile deployment, making its power solution requirements […]

Electric Vehicle technology and the role of Permanent Magnets

European legislation to phase out vehicles equipped with the internal combustion engine has led to a shift in the market – making way for Electric Vehicle technology to be embraced. Permanent Magnet BLDC drives have been identified as the most promising technology to provide the attributes required for modern Electric and Hybrid Electric Vehicles. Awareness […]

Makinex

Reliable mobile power – anywhere anytime   “Part of the design for the mobile Makinex Generator sets required sourcing the right light weight components which were robust, reliant and had the grunt when needed. RFL Alternators worked closely with Makinex to provide technical guidance and expertise and continues to be valuable partner to the business”, […]

Unbalanced Loads

For efficiency and maximum performance 3 phase alternators are the most common alternators on the market, however due to the very nature of the design they are required to work at a balanced load. Unfortunately, it is almost impossible and unrealistic to run 3 perfectly balanced loads. Any variation on any of the loads will […]

Generator Paralleling

The world is becoming more reliant on electrical power. Electrical power is required for a primary source of energy, back-up systems, military deployment and disaster relief. As technology increases the power demand grows, and systems can-not afford to go offline. This drives the requirement to have larger and more reliable generators. Larger generators become unpractical […]

Unbalanced Loading Behaviour

Abstract —Portable AC generators directly driving isolated AC loads require tight voltage regulation, good voltage waveform quality and high efficiency. This paper studies the performance of a 4 pole, 16 kW interior permanent-magnet generator under balanced 3ph and unbalanced 1ph resistive loading conditions. For the unbalanced 1ph condition, the use of star and delta winding connections […]
