The working principle of the electric mountain bike pedal assist system is to control the output power of the motor by sensing the pedal force to provide assist force to the rider.
In 2023 Mountain electric bike have become more and more popular in cities and have become a convenient way for people to travel. One of the important technologies is the electric bicycle pedal assist system. This article will provide an in-depth analysis of the working principle of the electric bicycle pedal assist system, and take you to understand the mystery behind this technology.
Components of an electric bicycle pedal assist system:
The electric mountain e bikes pedal assist system is mainly composed of sensors, controllers, motors and batteries.
Mountain Ebike Peadl Assist Sensor
The sensor can perceive the rider's pedaling force, and the common ones are pedaling force sensor and pedaling speed sensor. The pedaling force sensor uses strain gauges or pressure sensors to measure the pedaling force of the rider, while the pedaling speed sensor measures the pedaling speed through the principle of magnetic field induction.
Mountain Ebike Peadl Assist Controller
The controller is the core component of the whole system, which receives the signal from the sensor and controls the output power of the motor according to the set parameters.
Mountain Ebike Peadl Assist Electric Motor
The motor usually adopts a DC brushless motor, through the adjustment of the controller, converts electrical energy into mechanical energy, and provides additional power to assist riding. The battery is used as an energy source to provide electrical energy to the electric motor.
The electric bicycle pedal assist system works as follows:
1. The sensor senses the pedaling force and rotational speed of the pedal, and sends the signal to the controller.
2. The pedal force sensor measures the output force through strain gauges or pressure sensors.
3. The pedal speed sensor measures the speed of the pedal through the principle of magnetic field induction.
4. The controller controls the speed and output power of the motor according to the signal from the sensor.
5. Through PWM technology, the controller adjusts the current and voltage of the motor to achieve precise control of the motor.
6. The electric motor converts electrical energy into mechanical energy, which is transmitted to the wheels through the transmission system to provide additional power to assist riding.
7. The rider can feel the obvious power boost effect when pedaling, which reduces the burden of pedaling and improves riding efficiency.
When the rider stops pedaling or reduces the pedaling force, the sensor will sense and send a signal to the controller. The controller adjusts the output power of the motor according to the signal of the sensor, making it stop or reduce the output power. Through the intelligent adjustment of the controller, the system can adjust the power according to the needs of the rider to ensure the stability and comfort of riding.
The advantages and applications of electric bicycle pedal assist system are as follows:
1. Reduce the pedaling burden of the rider, especially when riding for a long time or uphill, it can provide additional power support and make riding easier.
2. Adapt to different riding needs, such as mountain biking, long-distance riding, etc., and provide personalized power assistance.
3. To promote green travel and reduce environmental pollution has become an important choice for sustainable travel in modern cities.
