E bike, that is, electric power bicycle, that is, with electric drive auxiliary power, but still to human stampede drive based on the bicycle. In recent years, the power to help products bloom, domestic manufacturers also compete to participate in technology research and development, more and more good products are born like bamboo shoots after a spring rain, gradually into the daily life of motorists. However, electric power is still a new thing, and E-Bike related to a variety of words, today on the e bike parts to do a simple science.
According to the different position of the motor on the car, e bike parts motor is divided into two kinds : middle motor and hub motor. At present, the mainstream high-end brand of e bike parts are based on the middle motor, belongs to the industry's most cutting-edge level. The central motor is located in the frame part, with a gearbox structure, instead of the central shaft position; The hub motor is in the front and rear wheel of the flower drum parts, combined with the bicycle flower drum parts. The core technology of the electric Moped is not only the motor, but also a variety of complex sensors. Different manufacturers have their own patented technology to optimize the algorithm for different sensing parts. Generally speaking, the most important sensor of electric self-propelled bicycle accessories is the step frequency/torque sensor inside or around the motor. These sensors can sense the motion situation, transmit different signals to the controller for operation, realize the output change, and achieve the purpose of acceleration and deceleration. Current: How fast a car can go depends on the output of the motor, usually by controlling the output of the battery. The size of the current is controllable, controlled by the controller algorithm, with high accuracy, and constant current output, so that the output power of the motor can be stepless control.
Power: Usually when we say the motor power, we refer to the rated output power of the motor, that is, the maximum output power that can be operated normally for a long time under ideal conditions. Some people also call it the "maximum use power". Note that the rated power of the motor is not equal to the peak power. The greater the power, the more fierce the motor output, the more can measure an E-BIKE can be competent for heavy work, general mountain power booster model motor power will be higher, and urban and portable models are more miniaturized and balanced.
Torque is a special torque that makes the object rotate. The torque in E-BIKE parameters refers to the torque output from the crank end of the motor, reflecting the load capacity of the car in a certain range. Torque is similar to the trampling force applied on the crank. The larger it is, the stronger the motor output will be. It is more suitable for difficult riding occasions, such as mountain bike cross-country and rolling terrain riding.
After the motor directly rotates and outputs, a series of mechanical speed reduction devices are needed to amplify its original torque and reduce the speed, and the kinetic energy is indirectly applied to the crank and tooth disc. This motor output can be more gentle, auxiliary power feeling more simulated human trampling, also protect the motor, reduce the load pressure, delay the life of its internal mechanism, which is particularly important for the violent output of E-BIKE.
There are many e bike parts, battery, capacity, clutch and clutch ratchet, sine wave control, protection level is not introduced here
