2. When a motorized tricycle climbs a hill or a mountainous area, as long as the shift electronic switch is pressed, the signal generator outputs the signal and controls the drive to ensure that the DC drive motor performs a reliable operation on the shift mechanism and the differential speed of the DC brushless motor is changed. The gear mechanism is in a low-speed operation state. At this time, the DC brushless controller drives the DC brushless motor to keep the high efficiency, high current, and strong torque to make the electric tricycle run smoothly. Jiangsu Zongshen leader in industrial technology innovation, pioneering the era of intelligent electric tricycle Simple structure, easy operation, high reliability, high safety, different road conditions, want to change, change, do whatever you like, and control! high speed rolling shutter door servo motor

Jiangsu Zongshen world's first intelligent CPU electronic shift tricycle in the industry
Subversion of the electric tricycle industry manual shift, Jiangsu Zongshen led the technical revolution of the electric tricycle industry. 
1. When the electric tricycle runs on the plains, the DC brushless controller directly drives the DC brushless motor to realize the flow of the three-phase windings of the brushless motor U, V and W, completes the commutation requirements, and makes the motor run normally. In the electric tricycle DC brushless motor controller, there are two or two power-on mode and three-three power mode.
Leading the electric vehicle industry in technological innovation and upgrading, creating a new category of high-end electric vehicles with Jiangsu Zongshen's first-class brand connotation. The utility model relates to an intelligent gear change control device for an electric tricycle, in particular to a signal generating device for automatic conversion of an electric tricycle to a plain and a mountainous area. The device includes a turn handle, a variable gear electronic switch, a DC brushless controller, a signal generator, a control driver, and a DC brushless motor differential gear shift assembly.
