The UK-based electric motor company Yasa<\/strong> broke its own record<\/strong> by achieving a power density<\/strong> of 59 kW\/kg<\/strong> with a short-term peak power<\/strong> of 750 kW<\/strong>. This development signals a new era<\/strong> in electric motors<\/strong>.<\/p>\n\n\n\n

Yasa<\/strong>, the UK-based electric motor company<\/strong> owned by Mercedes<\/strong>, broke its own record<\/strong> in terms of power density<\/strong>. The company, which reached 750 kW<\/strong> in short-term peak power<\/strong>, thus achieved a record<\/strong> value of 59 kW\/kg<\/strong> for its electric motors<\/strong>.<\/p>\n\n\n\n

In July, Yasa<\/strong> achieved a power of 550 kW<\/strong> with a weight of 13.1 kg<\/strong> with its new axial-flux motor prototype<\/strong>, which corresponded to a power density<\/strong> of 42 kW\/kg<\/strong>. According to the company’s statement, the latest tests with a lighter version significantly exceeded this value.<\/p>\n\n\n\n

The weight of the last tested motor<\/strong> is around 12.7 kg<\/strong>, largely surpassing the peak power performance<\/strong> from July. The 59 kW\/kg power density<\/strong> is approximately 40 percent higher<\/strong> than the previous tests.<\/p>\n\n\n\n

Yasa<\/strong> states that the current prototype<\/strong> was not developed solely for peak power performance<\/strong>. The company estimates that the “continuous power, which is very important for the new motor, will also be around 350-400 kW<\/strong>.” Yasa<\/strong> states that more details regarding the development of the said prototype motor<\/strong> will be shared soon.<\/p>\n\n\n\n

Yasa<\/strong> is a company specializing in compact axial-flux motors<\/strong>. In these motors, the magnetic field<\/strong> travels along the rotation axis<\/strong> of the rotor<\/strong>, rather than outward from the center of the rotor<\/strong> as in classic motors. This arrangement increases power density<\/strong> and generally makes the motors smaller. Axial-flux motors<\/strong> are usually developed in a disc-like<\/strong> form due to their component arrangement.<\/p>\n\n\n\n

Mercedes-Benz<\/strong> acquired the Oxford-based<\/strong> company in 2021<\/strong>. Two years later, Yasa<\/strong> introduced the Mercedes-Benz Vision One-Eleven concept car<\/strong> with its axial-flux motors<\/strong>. This technology<\/strong> evolved into the AMG GT XX<\/strong>, which is equipped with three motors<\/strong> and broke several world records<\/strong> in August thanks to its efficiency<\/strong> and power output<\/strong>. The technology<\/strong> is not yet used in Mercedes’ production models<\/strong> but is being applied in some hybrid supercars<\/strong>, including Ferrari models<\/strong>.<\/p>\n\n\n\n
