Tailing patented high-efficiency motor. The highest grade SH magnetic steel (magnetic steel grades M, S, H, SH) is adopted, and the magnetic steel sheet (Bell 24-35 mm, common in the industry 18-2 1 mm) is added to effectively increase the magnetic flux. The coil adopts ternary winding technology, which greatly improves the working efficiency of the motor, with small resistance, strong heat dissipation, large torque and greater power. Compared with ordinary electric vehicles, its advantages are fully embodied in "one province and three more". That is to save money; More than twenty, running twenty kilometers more when charging; More than 7 thousand, running more than 7 thousand kilometers a year; One more year, how far you can save electricity and use the battery for one more year.
We know that the depreciation process of motor is closely related to magnetic steel, and its working cycle is related to the temperature resistance of magnetic steel. Generally speaking, M is resistant to 80 degrees Celsius, S is resistant to 100 degrees Celsius, H is resistant to 120 degrees Celsius, and SHY is resistant to 150 degrees Celsius. When the above four grades exceed its rated temperature, it is easy to lose excitation; If the magnetic field drops too much, your electric car will fall into the strange circle of "short driving range, sudden drop of load, weak climbing and substandard riding time".
The technical index of Bell's high-efficiency energy-saving motor far exceeds these four grades, and its temperature resistance is 180 degrees Celsius. Therefore, the bell motor is not easy to lose excitation, with stable performance, strong power, high speed, strong climbing ability, long running distance and long service life. Coupled with the intelligent chip in the controller, the fashionable Bell fully automatic "Four Inventions" series of electric vehicles on the market are deeply loved by consumers.
