The SF5 will be available for pre-order by the end of 2018 and is scheduled to hit the road in 2019. The company plans to begin vehicle production this year at its facilities… Read more »
SF Motors acquires Martin Eberhard’s battery module startup InEVit
SF Motors, a Chinese-backed company with big plans to build next-generation EVs, has announced the acquisition of InEVit, a battery modularization startup headed by Tesla co-founder Martin Eberhard. Eberhard was already working with SF Motors as a strategic advisor, and will now serve as Chief Innovation Officer and Vice Chairman of the Board. InEVit has… Read more »
SF Motors to produce EVs at former Hummer factory
Poetic justice department: SF Motors, the new Chinese EV brand that recently opened an office in Silicon Valley, has bought an auto assembly plant where smoke-belching Hummers used to roll off the line, and plans to convert it to an EV manufacturing plant. AM General’s South Bend, Indiana plant also used to assemble SUVs for… Read more »

The company is launching an EV brand called SF Motors, which it promises to unveil in further detail in the coming months. The company has also established an R&D center… Read more »
Schaeffler provides in-wheel motors to municipal utility EVs
Three small municipal vehicle manufacturers will use Schaeffler’s electric wheel hub motors in the next few months, including Jungo, which will debut a multipurpose car using Schaeffler wheel hub motor technology. The manufacturers will use the motor in road sweepers, vans and snowplows. The new wheel hub motors incorporate all propulsion and braking components inside… Read more »
Alternatives to permanent magnet motors in EV traction applications
In my very first article for Charged over 10 years ago, I opined that the Switched Reluctance Motor, or SRM, would eventually come to dominate the EV traction market, if for no other reason than the fact that it is almost as cheap as dirt to manufacture. I won’t sprain my shoulder patting myself on… Read more »
Testing e-axle lubricants to enhance heat transfer, copper compatibility and durability performance (Webinar)
EV lubricants are becoming more important than ever with new applications such as e-axle fluids and new performance requirements. Initially, for Driveline e-fluids the primary drivers were efficiency and wear performance. However, there is now an increasing focus on heat transfer and copper compatibility requirements. All of this without sacrificing any durability performance. In addition… Read more »
A closer look at brushed AC motors in EVs
Everything old is new again: BMW’s fifth-generation eDrive features a wound-field synchronous AC motor Brushed DC (and AC/DC universal) motors are much maligned for a number of reasons, but one of the chief—if, perhaps, somewhat exaggerated—complaints is that the graphite brushes, and the segmented copper commutator they ride on, wear out over time, all the while producing… Read more »
Infinitum Electric brings its PCB stator technology to EV motors
Infinitum Electric says its axial flux motors with printed circuit board stators offer weight reduction, cost reduction and efficiency gains. Batteries are getting a lot of media coverage these days—they represent a rapidly-developing technology that’s seen as the key to the electrification of transport. Motors, however, are considered a fairly mature technology, and the humble… Read more »
