The world's first run in automatic control mode of stepping motor and the world's first heavy-duty multi rotor stepping motor and was born in Hubei, Xiangfan amateur inventor hands to celebrate, he is the two new concepts of the stepper motor, motor family has added two new members, especially the birth of multi rotor heavy the stepper motor, the traditional concept of he completely broke the traditional motor can only have a rotor, the highest can have up to 12 of the rotor can be strong, so the power output of engine and the like, is worthy of the name fighter, he not only has high power, large torque, low energy consumption, but also has high speed self generating function, active operation he is passive he is running the motor permanent magnet generator, but also has independent braking function, simple structure and easy control, only need a simple electric Pressure control can realize global speed regulation, which has the incomparable superiority of conventional motor. The birth of multi rotor motor provides the direction for the future development of the motor, the motor will enter the future multi rotor motor era, once in the multi rotor era, is the electric car completely replace fuel car era!!! As an amateur inventor, we sincerely hope that these two inventions will arouse the attention of people of insight!!!
