Murata has launched its first series of high-performance coreless current sensors using tunnel magneto-resistive (TMR) elements (writes Nick Flaherty). The MRD series of open-loop current sensors integrates high-performance TMR elements. These use a magneto-resistive effect that occurs in a magnetic tunnel junction composed of two ferromagnets separated by a thin insulator. The insulator, typically a […]

Sigma Powertrain EMAX transmission

Rory Jackson explains how this modular all-electric gearbox can combine two motors to drive any size and weight of EV. High-voltage electric motors produce torque across a wide range of their rpm bands, enabling most electric cars on the road these days to achieve reasonably high power efficiencies with single-speed gear reductions.

Challenge of batteries for heavy-duty EVs

High-voltage batteries are indispensable for the electrification and decarbonisation of vehicles worldwide, but the specific energy and energy density limitations of current battery technology bring challenges to the forefront when optimising different kinds of EVs. Take heavy-duty commercial EVs, for example. Whether electrifying an 18-wheel truck, a coach, a city bus or some similar sort of long-endurance fleet vehicle, hundreds of kilowatt-hours of energy need to be stored onboard.
