This Is The World’s Most Durable E-Motor – And It Can Run Continuously At Over 90% Peak Output

German automotive parts manufacturer MAHLE has announced a “superior continuous torque” (SCT) motor that it says is the “most durable electric motor” ever, a press statement reveals.

This new motor will run at over 90 percent of its peak output non-stop without overheating. It also works without any magnets.

Electric motors are given separate peak and continuous power ratings because they can get overheated and damage components when running on peak output for a long time. Usually, E-motors have thermal limiting systems that cut down power output at the first signs of overheating.

The company says its SCT motor has a continuous power rating of over 90 percent peak power. It employs a unique oil cooling system that guides oil through a central intake. The motor then uses the centrifugal force generated by the spinning rotor to pump that oil around the surrounding stator coils. The heat is extracted out through a radiator, and it can also be used elsewhere in an electric vehicle if required.

As a point of reference, MAHLE says its motor can haul a large electric truck up steep mountain passes or perform multiple sprints on race tracks without overheating.

“Building large electric motors that deliver short-term high performance is easy. What was still lacking on the market until now were durable yet compact drives to make electric vehicles unrestricted for everyday use,” Martin Berger, Vice President of Corporate Research and Advanced Engineering at MAHLE explained in the company’s statement. “Our new SCT E-motor is the solution,” he added.

This motor uses neodymium magnets. However, the company says that, in principle, the novel concept will also work well in its magnet-free motor designs.

The SCT motor will be presented to the public at the IAA Transportation event in Hanover, Germany in September. The new design will massively enhance electric vehicle efficiency. The compact size of STC makes it cheaper and makes it weigh less, allowing for higher load capacities and higher power-to-weight ratios allowing EV sports cars to perform unhinged at the race track.
