Artemis Intelligent Power

Last updated

Artemis Intelligent Power (AIP) is an engineering and R&D company based in Edinburgh, Scotland. It primarily manufactures hydraulic machines and transmissions that are based on high-speed solenoid valves and digital control technology. The company is noted for developing its digital displacement technology. [1]

History

The company emerged from a University of Edinburgh project initiated in 1994 by Win Rampen and Stephen Salter with a focus on producing high-tech machines to generate renewable energy and reduce fuel consumption of vehicles. [2] [3] The UK Carbon Trust supported the research project splitting off into a fully operational company in its development of its hydraulic transmission system. [4]

AIP stated that its digital displacement hydraulic pump (DDP) technology can deliver greater efficiency and productivity, particularly when applied to off-highway machines. [5] The technology was first used to power wind turbines and increase their efficiency. It was a recipient of the Royal Academy of Engineering’s MacRobert Award for Innovation. [1] [6] [7]

One of the challenges that the technology addressed was wasted energy. Recently, AIP's hydraulic pump technology was adopted by the train operator ScotRail, allowing its trains to save 9,000 liters of diesel per carriage every year. [8] The company claimed that from 64 to 73 percent of a train's energy is lost during braking and transmission. The AIP hydraulic pump eliminated the incidence of wasted energy through its computer-controlled valves that turn off the pump's cylinders when unused. [9]

Acquisition

Mitsubishi Heavy Industries acquired AIP in December 2010. It became a wholly-owned subsidiary of the Japanese company through Mitsubishi Power Systems Europe (MPSE). MPSE targeted to build an offshore wind park project for a UK Government national initiative. [10]

In 2018, the Danish multinational company Danfoss acquired AIP. This created a joint venture with Mitsubishi. [11] Danfoss completely acquired Artemis Intelligent Power in 2021, effectively retiring the brand. Its products are now available in the market using the name Danfoss Digital Displacement. [1] [12]

Aside from its hydraulic system, AIP also holds several patents such as those involving high-capacity, high-speed, and digitally-controlled valves. [10] AIP has partnered with other companies to develop projects such as infinitely variable hydraulic transmission systems and the hydraulic energy storage technology, [13] including the world's first tidal energy blade research center FastBlade constructed by Babcock International and the University of Edinburgh.

<span class="mw-page-title-main">Fluid power</span> Use of fluids under pressure to generate, control, and transmit power

Fluid power is the use of fluids under pressure to generate, control, and transmit power. Fluid power is conventionally subdivided into hydraulics and pneumatics. Although steam is also a fluid, steam power is usually classified separately from fluid power. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid power systems today are usually within a single building or mobile machine.

A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant angular velocity while the vehicle moves at varying speeds.

Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses, tubes, or pipes.

Variable displacement is an automobile engine technology that allows the engine displacement to change, usually by deactivating cylinders, for improved fuel economy. The technology is primarily used in large, multi-cylinder engines. Many automobile manufacturers have adopted this technology as of 2005, although the concept has existed for some time prior to this.

The production of renewable energy in Scotland is a topic that came to the fore in technical, economic, and political terms during the opening years of the 21st century. The natural resource base for renewable energy is high by European, and even global standards, with the most important potential sources being wind, wave, and tide. Renewables generate almost all of Scotland's electricity, mostly from the country's wind power.

Variable valve lift (VVL) is an automotive piston engine technology which varies the height a valve opens in order to improve performance, fuel economy or emissions. There are two main types of VVL: discrete, which employs fixed valve lift amounts, and continuous, which is able to vary the amount of lift. Continuous valve lift systems typically allow for the elimination of the throttle valve.
