Diodes adds 100 V, 1.5 mΩ MOSFET for 48 V automotive motor drives and OBCs


Diodes Incorporated has expanded its automotive-compliant PowerDI8080-5 MOSFET lineup with a new 100 V N-channel device that the company says offers industry-leading on-resistance for 48 V automotive designs. The new DMTH10H1M7SPGWQ features a maximum RDS(on) of 1.5 mΩ and is aimed at 48 V BLDC motor drives in applications such as electric power steering and… Read more…

Scalvy says its modular EV battery architecture hits 98.3% inverter efficiency, targets 15% longer pack life


Scalvy says a joint concept evaluation with Valeo has validated its modular battery-integrated power architecture for EVs under WLTC operating conditions, marking a step toward automotive deployment of the company’s distributed “Power Neuron” platform. Instead of using separate centralized inverters, DC-DC converters and onboard chargers, Scalvy’s architecture distributes those functions into compact modules at the… Read more…

SciMo bets automated flat-wire windings can beat hand-built specialty motors in high-performance niches


In electric motor engineering, copper is king, and winding architecture is one of the main levers engineers use to balance power density, efficiency, cooling and manufacturability. Higher copper fill in the stator can reduce winding resistance and improve current loading for a given package size, but only if the design also manages the magnetic, thermal… Read more…

Heybike Villain review: 4.2kW pit bike hits 45+mph for $1400

Electrek

I’ll be honest with you: when Heybike first teased the Villain ($1399), my reaction was somewhere between amazed, intrigued and skeptical. Heybike makes fantastic commuter e-bikes and impressive folders: the kind of bike your unc (me) buys to ride to the farmer’s market. So when they showed up at CES with a Sur-Ron-ish-style electric dirt bike claiming 45 mph and 190 Nm of torque, at less than half the price, I had serious questions. Read more…
