More Efficient Electric-Car Motor? Startup KLD Claims It Has One

KLD EnergyKLD’s OneDrive motor.Mass-market plug-in cars have only appeared in showrooms for three years, but startup KLD Energy Technologies thinks it’s already time for a revolution.
KLD says its updated electric motor and battery pack, called OneDrive, can get the same range from a 3-kilowatt-hour battery pack as normal motors get from a 5-kWh pack.
How does the new motor do it? OneDrive uses the same 18650-sized lithium-ion cells (they’re essentially laptop batteries) as a Tesla Model S, but its cells are a different type.
KLD says it uses power cells more similar to those used in hybrid cars, not the energy cells used in other plug-in car powertrains.
Power cells are designed with lower resistance, allowing them to discharge more quickly while generating less heat. This suits hybrids, which cycle their battery packs through a narrow charge range tens of thousands of times.
The startup also changed its motor design, using a permanent-magnet brushless motor with amorphous metal for the stator.
Unlike other metals, amorphous metals can’t retain a magnetic field. That means they will stick to a magnet, but won’t retain any residual magnetism when separated from it.
KLD says using this material in its motor’s stator also reduces resistance, improving efficiency.
The motor also doesn’t have
