| A company based in the United Kingdom claims to be developing the world's most power dense electric motor for automotive applications. Equipmake said its new Ampere motor will develop 20 kilowatts (27 horsepower) per kilogram. The company claims it is four times the power density of conventional motors. Total output will be 220 kw (295 hp) at 30,000 rpm, with a weight of less than 22 pounds (10 kg), according to Equipmake. The motor will feature 3D-printed parts from a second company, HiETA. 3D printing will provide greater thermal efficiency by allowing metal parts to be made as thin as possible, according to HiETA. Equipmake did not say what vehicles might use the Ampere motor. According to the company's website, Equipmake is contracted to supply powertrain components for the Ariel Hipercar hybrid, and also supplies powertrains for electric buses. Electric motors are becoming a point of pride for automakers and suppliers, just as internal-combustion engines have been for a century. |
