We know that High torque needs rare earths What if we remove them completely? Yes, this Axial SynRM looks practical 👇 In my motor development experience, Material cost always becomes a bottleneck. I was reading about the NAFTech project. Typical PMSM uses 20–30% magnet cost. Their SynRM reduces this to near zero. First, why and what is a rare earth? Like neodymium and dysprosium. They give high magnetic strength. But prices are volatile. Supply chains are concentrated glob

The next big question in EVs: Lithium-ion vs Aluminium-ion? I believe the Aluminium-ion could be a game-changer — let’s explore why!👇 The EV industry is buzzing with speculation. Many believe Tesla is working on a “Super Aluminium-ion Battery.” While there is no official confirmation, the idea excites researchers and consumers alike. 👉 Why Aluminium-ion? Aluminium is the most abundant metal in Earth’s crust. It carries three electrons per ion (vs one in lithium). This means

More speed. Less material. Better efficiency. 30,000 rpm motors are not future talk. They are already entering mass production. I came across this PUMBAA update recently. It got me thinking deeply. Most EV motors peak near 6,000 rpm. Beyond that, torque starts dropping. That limits high-speed acceleration. Now imagine pushing 30,000 rpm. System design changes completely. Higher speed means smaller motor size. Less copper and magnet needed. Even core material reduces significa

Everyone is focused on EV launches. Almost no one is talking about- What actually decides the winners. Lately, I’ve been noticing a Silent shift in the EV space. From “launching vehicles.” to “building platforms.” Yes, you read it right The real game is happening At the system level. The focus is moving toward Scalable motor architectures, software-defined control, and data-driven improvements. Early architecture decisions Don’t just define performance— They define co

750 kW, 94 kg delivering 8 kW/kg Hairpin windings are redefining motor design. Fraunhofer IISB’s aircraft motor proves it. I was reading this Fraunhofer IISB 's Hybrid-electric regional aircraft motor. It built something impressive. The motor of 750 kW, 94 kg Delivering 8 kW/kg Typical EV motors: ~2–4 kW/kg Speed reaches 21,000 rpm. Torque is 350 Nm. Cooling uses direct oil spray. Rated at 65°C coolant. They used NO15 electrical steel. Thickness is just 0.15 mm. This red

I just saw a motor using 0.025 mm steel That’s 10x thinner than usual. Can push motor efficiency to 98.2%. Horse Powertrain unveiled a new motor technology. It uses ultra-thin amorphous steel layers. Amorphous steel lacks a crystal structure. So magnetic losses reduce significantly. The stator is the motor’s stationary core. Magnetic fields rotate inside this structure. Traditional steel sheets are much thicker. This design uses just 0.025 mm sheets. Iron loss means waste

Nobody explains this about EV motors. The biggest innovations are hidden inside the stator. Many EV innovations are visible. Bigger batteries. Faster charging. But motor innovation is often invisible to most users. 🧲 Slot design. Copper layout. Cooling paths. Small changes inside the motor create big efficiency gains. Even 1–2% efficiency gain here directly improves vehicle range. What matters more in EV motors: magnets, copper design, or cooling? ⚡ Let's discuss. 🔔 Follow

80 kW peak motor. 8500 rpm. 95% efficiency. 12.7 kWh LiPo batteries. This powertrain just pushed an electric race boat to 91.58 km/h. 🚤 I recently learned, high-speed racing boats are going electric. And racing in Formula-60 events. Recently, I spoke with Stephane Collard , Co-Owner at Protenergies, a company working on electric boat conversions. He shared some interesting insights. I thought it is worth sharing. This industry is quietly emerging. Here is how their ecosyste
