Rostec's KRET develops eight drone and robot motors a third the weight of earlier ones

KRET, the electronics group of Russia's state corporation Rostec, has developed eight new compact electric motors for drones, robots and other civilian machines, its press service said. At about 2,000 W, they weigh 140 grams, a third of the weight of the earlier versions.

The motors are brushless, which reduces wear and energy losses. Among them is the DMR 2854 stepper motor, rated at 2,500 W at 30 V, for industrial robots and other machines that move heavy parts, with loads of up to 600 kg. KRET now offers 22 motors, all made from Russian components.

Alexey Melnikov, KRET's deputy director general for civilian products, said Rostec wants its own components that perform better than the foreign ones they replace.
