Problems solved by technology

The brushless hub motor, brushless differential motor and series excitation motor used in the original electric tricycle and electric vehicle motor technology, these three motors are designed considering the speed of electric vehicles and the reasonable balance of load, climbing and speed. They cannot meet each other, and the starting current is large, which reduces the service life of the battery, resulting in the amplification of the motor power, energy waste and large consumption of magnets, especially the series excitation motor, which not only has low efficiency, but also has short service life and other shortcomings.
