Groupe PSA and Nidec form JV for automotive traction motors

Groupe PSA, owner of the Peugeot, Citroën, DS, Opel and Vauxhall brands, and Nidec Leroy-Somer, a French manufacturer of small precision motors, plan to form a joint venture to develop a range of traction motors for electrified vehicles. The 50/50 JV will receive an initial investment of €220 million ($262 million). The main components of… Read more »

Visedo’s SRPM motors for buses claim 10% more power, better cooling

Finnish manufacturer Visedo has unveiled a new electric motor design optimized for the e-bus market. Visedo says its new S-model PowerDRUM has achieved a 10% increase in power output, as well as better cooling. The company has upgraded its entire PowerDRUM line, which includes motors in 4 different sizes, ranging from 50 to 343 kW…. Read more »

Making a motor: Many automakers rely heavily on third party motor-winding experts like Odawara Engineering

Electric motors are everywhere: in household appliances, in hand tools, in buildings, in consumer electronics, and increasingly in automobiles. Motors are used in windshield wipers, power windows, throttle controllers, and, more and more, in the drivetrains of electrified vehicles. Electric motors abound, and Odawara Engineering knows how to make them. Charged spoke with Odawara’s Chris… Read more »

A closer look at rare earth permanent magnets

Rare earth magnets have gotten a lot of coverage in the EV press over the years for being expensive – especially back in 2011 when a supply disruption in China sent the prices up anywhere from fivefold for neodymium to 20-fold for dysprosium over the course of a few months – yet they are still… Read more »

IAV says its new modular electric drive can boost range 5-10%

IAV’s new modular drive unit, presented at the recent Vienna Motor Symposium, combines an 80 kW (50 kW continuous) motor with a transmission, and can support electrification solutions in vehicle classes A to D. Many of today’s electric drives use a transmission with a fixed gear ratio. This has the advantage of simplicity, but is… Read more »

Copper industry expects EVs to spur ninefold rise in demand for copper by 2027

Big Oil may not be too happy with what’s going on, but Big Copper is all for it. A new report commissioned by the International Copper Association (ICA) finds that the growing market for EVs will significantly increase demand for copper over the next decade. According to Copper Intensity in the Electrification of Transport and… Read more »

EV tech explained: What are the limiting factors of an EV’s regenerative braking force?

In many EVs, regenerative braking is limited by the manufacturer to a modest level, and usually offers little or no ability for the driver to adjust it (aside from the few cases in which regen is made proportional to the initial movement of the brake pedal). Is tepid regen braking the result of some sort… Read more »

Magnet Applications’ new B12 neodymium compression-bonded magnets

Magnet Applications has announced a major upgrade to its neodymium compression-bonded magnet product offerings. The new B12 magnet has a typical maximum energy product (BHmax) of approximately 12 MGOe, compared to the previous generation’s 10 MGOe. The BHmax of a bonded magnet is determined by the density and the volume fraction of the magnetic material… Read more »

Carpenter Technology develops a new soft magnetic alloy with key benefits for EV motors

Electrical steels are soft magnetic materials found at the heart of electric motors. They’re typically manufactured in cold-rolled strips, cut into shapes to make laminations and then stacked together to form the stator and rotor of a motor. These specialty steels are tailored to produce certain magnetic properties, and have a magnetic flux density (key… Read more »

Tesla’s chief motor engineer discusses the potential of next-generation motor technologies

Tesla spends a considerable amount of resources on basic research into EV systems – as well it should. EV technology is very young compared to that of ICE vehicles, so it’s safe to assume that, in a few short years, the aggregate of many incremental technology advances could lead to significantly better EVs. Of course,… Read more »
