Turntide Technologies has acquired UK-based AVID Technology, a cleantech engineering firm that manufactures electrified powertrain components for EVs and hybrids. Turntide’s Smart Motor System may reduce energy consumption by nearly 64%, and is free of the rare earth minerals that most higher-efficiency permanent magnet motors require. The company has been on an expansion spree lately,… Read more »

Magnetic nanoparticles pull valuable elements from water sources
Using magnetic nanoparticles to capture valuable materials from brines could help make the US a producer of minerals used in electronics and energy production. Today, most of these minerals are obtained from international sources, many of which are located in high-conflict regions. The patent-pending technology, developed at the DOE’s Pacific Northwest National Laboratory (PNNL), has… Read more »
Drive System Design’s software tool identifies optimal EV powertrain
Drive System Design (DSD), a specialist in the rapid engineering and development of electrified propulsion systems, has enhanced its proprietary Electrified Powertrain Optimization Process (ePOP). This software-based tool is designed to help e-mobility providers swiftly identify the propulsion systems that best fit their specific needs. DSD says its comprehensive analysis tool can quickly review tens… Read more »
A closer look at axial flux motors
In Issue 49, we reviewed some of the more promising advancements in materials and construction techniques for EV traction motors, one of which—the axial flux design—will be the focus of this article. Despite being characterized as an advanced construction technique, the axial flux design is actually one of the oldest ways of constructing a motor—it’s… Read more »
Draper wins patent for electrostatic motor
Draper is developing a family of electric motors and generators based on fundamentally different principles from common e-motors used today. Underpinning the initiative is a recent patent on aspects of the technology. Draper says its approach to electric motors has numerous advantages over conventional electric motors, including lower weight, higher efficiency, higher specific power and… Read more »
OXIS Energy to power luxury yacht with Li-S batteries
Yachts de Luxe (YdL) of Singapore has signed a ten-year contract with Oxis Energy valued at $5 million to build the world’s first luxury boat to be powered by Lithium-Sulfur (Li-S) batteries. The objective is to achieve a range of 70 to 100 nautical miles at cruising speed. Oxis will work with YdL to design… Read more »
Momentum Technologies licenses ORNL process to recover metals from batteries
Momentum Technologies, a Dallas-based materials science company focused on extracting critical metals from electronic waste, has licensed a process developed by the Oak Ridge National Laboratory (ORNL) for recovering cobalt and other metals from spent Li-ion batteries. Several critical elements, such as cobalt, nickel, lithium and manganese, are used in EV batteries. Using ORNL’s Membrane… Read more »
Linear Labs raises $6 million to expand EV motor manufacturing in Texas
Electric motor manufacturer Linear Labs has raised an additional $6 million in funding to further develop manufacturing capabilities and grow its employee base. The new capital raise comes shortly after the announcement of a $68.9-million partnership with the City of Fort Worth, Texas, which includes an incentive package for Linear Labs’ plans to develop an… Read more »
Advances In Switched Reluctance Motors: The Future of Mobility
Today’s EVs are primarily driven by permanent magnet motors. The future of these motors depend on the availability of rare earth minerals, which are environmentally devastating to produce and monopolized by one country, China. Switched reluctance motors (SRMs) are an emerging alternative, with decades of reliability testing in zero-fault-tolerant applications, and no rare earths…. Read more »
Bentley looks to the future of EV motors
Bentley Motors has concluded a three-year research study intended to transform EV powertrains, using a fully integrated e-axle that doesn’t use rare earth magnets. Bentley’s OCTOPUS (Optimised Components, Test and simulatiOn, toolkits for Powertrains which integrate Ultra high-speed motor Solutions) study led to an electric drive system that eliminates the need for both rare earth… Read more »
