Wolong introduces efficient motors for DC cooling applications

Wolong Electric America, a developer of industrial motor and drive technology, has introduced its Permanent Magnet Direct Drive (PMDD) motors, highlighting their ability to improve energy efficiency and reduce heat generation in high-demand environments such as data centres. Designed to operate without belts or sheaves, PMDD motors use a direct drive system that reduces mechanical complexity and common failure points, improving reliability and minimising maintenance requirements. The approach should also reduce mechanical stress and radial load on bearings, contributing to a longer service life. Lower heat output and energy use in data centres At the core of each motor is a rare earth magnet design that delivers stronger magnetic fields in a compact form factor. This aims to enable higher efficiency and cooler operation compared with traditional induction motors, which would be a key advantage in temperature-sensitive environments such as data centres, where controlling internal heat and power consumption are constant priorities. The motors are operated via a variable frequency drive (VFD), enabling precise speed control, smooth acceleration and deceleration, and reduced electrical strain on supporting systems. A 4:1 turndown ratio allows the motors to maintain torque and efficiency - including at low speeds - supporting variable airflow demands within cooling systems. Wolong Electric says its PMDD motors can be integrated directly into fan assemblies, reducing overall system losses and eliminating inrush current at startup. With reported efficiency improvements of around 20% over conventional induction motors, the design should contribute to measurable reductions in both energy use and waste heat. Flexible configurations for critical environments Wolong Electric says the PMDD motors can be tailored to specific applications, including data centre cooling systems, refineries, and OEM equipment such as heat exchangers. The motors are designed to operate at lower temperatures and with reduced maintenance demands, supporting long-term reliability and stable thermal management across facility operations. The company’s design approach hopes to enable easy integration with OEM and packaged system configurations, helping operators meet efficiency goals while aligning with evolving energy standards.

nLighten reports first ICFEn scores for UK, Germany, Spain

nLighten, a European data centre operator, has announced the first Integrated Carbon-Free Energy (ICFEn) scores for its data centres in the United Kingdom, Germany, and Spain, something the company considers a significant step in how environmental performance is measured within the sector. Developed in collaboration with the Fondazione Eni Enrico Mattei (FEEM), nLighten says the ICFEn framework introduces a more comprehensive approach to sustainability reporting by assessing hourly carbon-free energy matching, heat recovery, and contributions to grid stability. Unlike traditional metrics that rely on annual averages or focus solely on energy consumption, the company notes that ICFEn provides real-time insights into how facilities contribute to decarbonisation through energy reuse and system integration. A new framework for transparent environmental reporting The ICFEn model builds upon the 24/7 Carbon-Free Energy concept by including three key elements: hourly renewable electricity matching, heat recovery, and grid stabilisation. This combined methodology aligns with the EU Energy Efficiency Directive, as well as sustainability standards such as the Greenhouse Gas (GHG) Protocol and the Science Based Targets initiative. Chad McCarthy, Chief Technology Officer at nLighten, comments, “Traditional sustainability metrics have focused on the data centre’s electrical energy profile, but ICFEn integrates the data centre into a community energy system, accounting for both consumption and contribution. "By including heat recovery and real-time renewable energy matching, we’re offering customers and stakeholders unprecedented transparency about our environmental impact, hour by hour, not just as year-end averages.” nLighten’s facilities in the UK, Germany, and Spain achieved good ICFEn scores through renewable power purchase agreements and heat recovery initiatives. Its UK data centres recorded an ICFEn score of 94.61%, higher than the regional carbon-free energy grid average of 56.47%. The company achieves hourly renewable energy matching by integrating renewable assets into its portfolio and aligning their production with operational demand in real time. This aims to ensure that data centres are powered by clean energy when it is actively being consumed. Francesco Marasco, Vice President of Energy Operations and Sustainability at nLighten, adds, “We’re not just measuring renewable energy consumption, but quantifying environmental improvement through sustainable projects, for which we share the calculation method transparently. "The ICFEn methodology allows us to demonstrate measurable, system-wide benefits that lower community emissions. We encourage other operators to adopt this framework, as raising awareness of data centres’ environmental contributions benefits the wider sector.” Encouraging wider adoption nLighten has made the ICFEn methodology publicly available under a Creative Commons licence to encourage industry-wide adoption. The framework’s release coincides with updates to the GHG Protocol, which are expected to introduce hourly-based renewable energy reporting requirements. The company plans to extend ICFEn reporting to all European sites and introduce third-party verification of hourly energy and heat recovery data as part of its next phase of implementation.
