Tesla’s motor power is a core technology of Tesla. Here is some superficial analysis based on the data published.
Tesla has a maximum speed of 210KM, tire model 245/35R21, and a maximum tire speed of 1591rpm.
First gear reduction, reduction ratio 9.73:1, motor maximum speed 15480rpm, motor power (P85) 306kw, peak torque 600Nm.
One reason for the high power of this motor is the amazing maximum speed. You can choose a relatively large first-stage reduction ratio to reduce the demand for torque. In contrast, current domestic technology has worked very hard to reach 10,000 rpm. In the example, the power of 7.5Kw is generally at 1,500 rpm.
What’s even more powerful is its maximum torque of 600NM. Tesla has taken many measures to ensure the structure of the rotor and stator. Simply using copper instead of aluminum for the rotor cannot effectively increase torque, and Tesla has specially designed corresponding punching sheets that are optimized for frequency conversion, high power, efficiency, weight, cooling methods, etc. under automotive operating conditions. You can analyze it by looking at their patents.
The operating conditions of small cars are short-term, and 300KW will not work continuously for a long time, which means the average output is about 20Kw. Buddy's Veyron has 1,000 horsepower and can only drive at full speed for 20 minutes on a tank of gas. All the same.
