Quadrunner with a DA-90S motor

The leading project partner Andrey Lobov became famous for making a motor sled with a DA-90S motor modernized using Duyunov's technology and currently mass produced. "Emelya's sled" smashed it at the electric transport exhibition in Mitino. Then it was moved to "Etnomir" park where they amuse the visitors now. And there are a lot of things to be amazed at: a small-sized motor drives a vehicle weighing over a ton together with passengers.

DA-90S is universal, it can be installed on electric cars, quadrunners and motorcycles. Its application potential, specifically by Victor Arestov, is regularly announced in the news. The motor has 3 kW power and 74 N/m torque.

In summer of 2019 Andrey Lobov with the partners installed Duyunov's motor on a quadrunner and held a range of field tests. The quadrunner pulled a 2.5-ton Toyota Tundra with a rope up the hill with no visible strain. Moreover, the speed was limited to 45 kilometres for safety reasons.
This is what the power of the induction motor with "Slavyanka" combined winding is like being only 190 mm in size and weighing 9.5 kilograms!

Various test in harsh travel conditions showed that the motor was flawledd in enduring all the loads and its temperature didn't exceed 72 degrees.
The quadrunner demonstrated fast acceleration and maneuverability - and all of this without the loud motor noise.

This machine is another graphic example of the "Slavyanka" technology showing breakthrough results in real life applications.
