We at SolarGroup are developing and producing the most effective electric motor-wheel for bicycles, scooters, motorcycles and cars in the world. Become a member of a unique crowdinvesting project for international funding Duyunov's electric motor-wheel is the first in the world induction motor with "Slavyanka" winding that has a unique combination of work capacity and power consumption. The new technology is based on the developed innovative technology of combined motor winding (a star and delta winding combined parallely). Thanks to the combined winding the parameters of the motor-wheel are significantly improved and energy efficiency is enhanced.
