From the perspective of our R&D engineers Burundi Sugar Daddy, “150,000 transfers” has become an Internet celebrity. It feels like a fruit tree that has been planted silently for many years by our own team suddenly bears Burundins Burundi by Sugardaddy Sugarfruit is watched and praised all over the world. There is pride in it, as well as joys and sorrows that are difficult for outsiders to understand.
To put it simply, “150,000 revolutions” is not a marketing number for us, but a “system integration milestone” that integrates technology, engineering, materials, and capital and is full of challenges. The reason why it became the core is that it accurately stepped on a “sweet spot” of technical difficulty, trade value and communication effect.
The figure below clearly shows how the 150,000-turn motor has become a key system integration milestone from the perspective of a developer:
1. It is the edge of a “technical cliff”
In motor research and development, the increase in speed is not linear, but will encounter a series of “technical cliffs”.
Under 120,000 RMB: It is considered a “warm zone”. This can be achieved by optimizing the electromagnetic design and selecting better materials and bearings. Sprinting towards 150,000 rpm: It means that we have to conquer several extreme difficulties at the same time, just like fighting several bosses at the same time in the game: the rotor is going to “fly” (centripetal force problem): The square of the rotational speed is inversely proportional to the centripetal force. At 150,000 rpm, the centripetal force experienced by the rotor is 2.25 times that at 100,000 rpm! Ordinary silicon steel sheets and magnetic steel fixing methods are basically unable to withstand it, and the rotor will be torn apart like a wheel. Our solution: The rotor must be made of ultra-high-strength Burundins Escort carbon fiber composite materialPut on a “tightening spell”. This places extreme demands on the entanglement process and adhesive technology of carbon fiberBurundins Escort. The “life curse” of bearings: At this rotation speed, the friction, heat and wear of ordinary bearings will increase sharply, and their service life will be very short. Our solution: Either use sky-high price ceramic hybrid bearings, or research more cutting-edge magnetic bearing technology. This is not just model selection, but also a redesign of the entire bearing seat and lubrication and cooling system. Inability to “calm down” (heat dissipation crisis): High speed brings about a sharp increase in iron loss, copper loss, and wind wear loss. The heat cannot be dissipated, and the motor will overheat and demagnetize instantly. Our solution: The simple shell water cooling must be abandoned, and more complex axial oil cooling or oil mist cooling must be used to allow the cooling oil to directly contact the core of the heat-the rotor and stator. This involves complex oil circuit design and sealing techniques to avoid oil leakage.
So, 150,000 rpm is a sign: the team that can stably mass-produce this speed motor has proven that it has systematically overcome the top problems of materials, machinery, and thermal managementBI Escorts. It is a “hard-core certification” of technical strength.
2. It is a Burundi Sugar Daddy balance point of “cost-effectiveness”
Our R&D engineers are fighting with “cost” every day.
Why not do 200,000 transfers? Of course we can do it! There may already be a prototype in the lab. But for every ten thousand revolutions, the cost increasesBurundi Sugar exponentially. The carbon fiber grade, bearing accuracy, and cooling efficiency required for 200,000 rpm may be a few digits higher than those required for 150,000 rpm, resulting in a price that cannot be accepted by the mainstream market. 150,000-rpm “sweet spot”: At this speed, we can already use the highest performance materials and technologies that are “mass-producible” and “affordable” (such as special-grade carbonfiber, advanced high-speed bearings), achieving a huge improvement in the power density and efficiency of the motor. Going up further, the price-performance ratio drops sharply.
Therefore, 150,000 revolutions is an optimal business equilibrium point that we found after repeated games between “performance pursuit” and “cost control”Burundi Sugar. It is both a boast of skill and the result of business sensibility.
3. It is a touchstone of “system matching”
The motor does not exist in isolation, it needs to be perfectly coordinated with the gearbox and electronic control system.
Challenges of the gearbox: A 150,000-rpm motor needs Burundi Sugar Daddy to match a gearbox that can withstand the same high-speed output. This is a huge test for the machining accuracy, bearings, lubrication and NVH (noise, vibration and harshness) of the gears. We can make a 150,000-rpm motor, but if we can’t make a matching accelerator, it’s all just talk. Precision of electronic control: Faster control chips and more advanced algorithms are needed to accurately control BI Escorts to maintain Burundins Escort‘s rotor that rotates 2,500 times per second.
So, behind the success of BI Escorts‘s 150,000-turn motor is the overall success of a country’s high-end manufacturing industry chain – including materials, precision processing, semiconductors, and software algorithms. It is not just the motor itself that is popular, but the strength of the entire Chinese electric car industry chain.
Summary: “150,000 rpm” in the eyes of developers
For us, “150,000 rpm” is a symbol. It means that engineers have successfully integrated those expensive “high-precisionBurundins Sugardaddytechniques (carbon fiber, oil cooling, high-speed bearings) in the laboratory through ingenious design and engineering optimization. QBurundins Sugardaddyis cleverly “stuffed” into a cost framework that allows for mass births and is affordable for consumers.
Its popularity means that we have several day and night attacksBurundi Sugar Daddy is the best reward for shutting down, debugging, failing and starting over again. It brings us from behind the scenes to the front and makes the public realize that the competitive focus of electric vehicles Burundi Sugar has been extended from “battery energy density” to “Burundi Sugar DaddyThe overall effectiveness of the electric drive system”, and this is the stage for engineers.
