Quotation of motor controllers for Tricycle Motorcycle

Motor controllers for Tricycle Motorcycle have developed so fast in recent years that it is unimaginable that the operation is becoming more and more foolish, while the display is becoming more and more complicated. For example, the control of vehicle speed has been developed to cruise lock. In terms of driving, some have electric performance and power assist function at the same time. , the power assist can be performed or the size of the power assist can be determined.

1. Controller and protection function
(1) Introduction to the controller Briefly speaking, the controller is composed of peripheral devices and the main chip. Peripheral devices are some functional devices, such as execution, sampling, etc. They are resistors, sensors, bridge switch circuits, and devices that assist single-chip microcomputers or application-specific integrated circuits to complete the control process. Single-chip microcomputers are also called microcontrollers. Memory, decoder with changing signal language, sawtooth wave generator and pulse width modulation function circuit, and can make the power tube of the switching circuit turn on or off, and control the turn-on time of the power tube by square wave to control the motor speed The drive circuit, input and output ports, etc. are integrated together to form a computer chip. This is the intelligent controller of the Tricycle Motorcycle. It is a high-tech product that appears in the face of a fool. The design quality and characteristics of the controller, the function of the microprocessor used, the layout of the power switching device circuit and peripheral devices, etc. are directly related to the performance and operating status of the vehicle, and also affect the performance and efficiency of the controller itself. Controllers of different quality, used in the same vehicle, are equipped with the same set of Gasoline Tricycle batteries with the same charge and discharge state, and sometimes there will be a big difference in driving ability.
(2) Types of controllers At present, the circuit principles of the controllers used in Gasoline Tricycle are basically the same or close to them. Most of the brushed and brushless DC motors use the PWM control method of pulse width modulation to adjust the speed, but the difference in the selection of drive circuits, integrated circuits, switching circuit power transistors and some related functions. The difference in components and circuits constitutes a big difference in the performance of the controller. There are two types of controllers in structure, which we call separate and integral.
Separate type The so-called separation means that the main body of the controller and the display part are separated and the latter is installed on the handlebar, while the main body of the controller is hidden in the box of the car body or the electric box, and is not exposed outside. This method shortens the connection distance between the controller, the power supply and the motor of the Gasoline Tricycle, and the appearance of the vehicle body appears simple.
The integrated control part is integrated with the display part and packed in a delicate special plastic box. The box is installed in the center of the handlebar. There are a number of small holes on the panel of the box, the hole diameter is 4~5mm, and a transparent waterproof film is applied on the outside. A light-emitting diode is arranged at the corresponding position in the hole to indicate the speed of the vehicle, the power supply and the remaining power of the battery.
