Hi community, Elon & Tesla team!, i'm not afraid to sound stupid, but I feel like I have to ask you, because I've been watching these guys(We are talking about Russian engineers who patented the combined type of winding) long time ago, and they're getting serious things by upgrading motors using this technology. So, did you hear something about asynchronous motors with combined windings, which allow to save up to 30% of energy, while having less heating, more traction, and other advantages of the induction motor? How do you think, it's possible to try this technology in Tesla? or already in use? there is an english version of their channel, just look. On Russian version they upload much more information. Just check these videos: https://www.youtube.com/channel/UCivix52j1cLjx6xGoR56WcQ/videos … They already tested this on Renault Twizzy(r/https://www.youtube.com/watch?v=1x0nN0L5tZs …) and got awesome results. I think using this technology in Tesla could give insane boost. All what you need is upgrade your (for ex. on Roadster) 3 motors on Roadster with that technology and then full test a car&motor, seems like it is works really good. Tesla could be much cooler with this thing. Ofcourse if this technology alredy not used(lol).
There some quotes from their website(Google translate):
Simple change of windings gives impressive results: Reduction of specific consumption electricity at 10-40% Improvement of vibro-noise characteristics, the average sound level is lower by 5dB Increased reliability: service factor 2.5 Higher starting moment at 40% Reducing the multiplicity of the launcher current at 40% A higher minimum moment at 40% Greater maximum moment 20% Obtaining efficiency and cos close to nominal in the load range from 20 to 140% 3.
Using this technology in Tesla could give awesome results, i think.
These engineers, Mr. Duynov & his son gave name SLAVYANKA to this type of winding. So what is SLAVYANKA?(Google translate) It is a technology for creating high-torque low-noise energy-efficient asynchronous motors. Slavyanka technology-the use of additional stator windings. For the three-phase electric motor are used in addition to the three main windings, three additional - combined - arranged in a certain geometric way and also in a special way connected to each other. This technology is patented. Advantage of technology Electric motors "Slavyanka" are an effective means of reducing energy consumption and operating costs. Advantages of electric motors over conventional asynchronous: To achieve high efficiency in the load range of 25 – 150% of nominal, that in real operation conditions allows to reduce the energy consumption by 15 – 50% The increase in maximum torque by 10 to 100% Increase the starting torque at 20 to 50% Reduction of starting currents in 2 times, which reduces the peak load on the network and eliminates the use of soft starters The reduction in noise levels by 6 to 7 dBA Reducing the heating temperature of the windings, which, in fact, eliminates the possibility of burnout of the windings.
P.S. I found it quite amusing that Tesla abandoned mirrors, receiving a 5% increase in the range of the maximum mileage, while such technology as combined windings in fact exists & works, and main idea that it could increase maximum range much more(not to mention the other parameter upgrades).
What do you think about this ?
