It just doesn’t make sense to repair it, because they are mass-produced and mostly made disposable. The primary function of an ebike controller is to accept input signals from the electric components (speed sensor, throttle, motor, battery, display) and then decide what signal to return to each of them. It also controls all the central safety and protection mechanisms of an e-bike. These protection functions include: 1. Over-current protection

A controller is composed of main chips ( microcontrollers) and peripheral components ( resistors, sensors, MOSFET, etc ). Generally, there are PWM generator circuit, AD circuit, power circuit, power device driver circuit, signal acquisition and processing circuit, over-current and under-voltage protection circuit inside the controller. Other multiple protection functions of the controller will be different from the controller's design. Following are some basic protection functions.Phase and battery current - The phase current is joined to the motor and can be higher than the battery current. Ensure that the phase current and motor current is matched otherwise the bike could overheat. The phase current and the current from the battery should be strictly distinguished. These are two different things. The phase current is connected to the motor and it can be much greater than the battery current. The core function of an electric bike controller is to take all the inputs from all the electric components ( throttle, speed sensor, display, battery, motor, etc.) and then determine what should be signaled in return to them (motor, battery, display). A controller is used to connect all electrical components of an e-bike together. Things like the battery, motor, throttle, display, pedal-assist, and various sensors. The controller basically acts as the “heart” for the e-bike. Please, follow these rules to avoid your electric bike overheating and to make your e-bike life longer:

BLDC motor with hall sensors controller. These kinds of motor controllers are based on the Hall Effect. The BLDC motor controllers equipped with hall sensors help to determine the rotor's position according to the stator. It is the motor's fixed part and the rotor consists of the rotating part. Besides, it helps in determining the speed along with other attributes that are needed to run the BLDC motor effectively. Furthermore, the sensors are called rotary encoders that determine the rotor's position. Tips for Choosing the Right Ebike Controller The electric bike controller is one of the main parts of an electric bike, it is the brain of the e-bike, controlling the motor ’ s speed, start, stop. It is connected to all the other electronic parts such as the battery, motor, and the throttle(accelerator), display(speedometer), PAS or other speed sensors if exist. Brushed DC motor controllers are often used in small electric vehicles such as small scooters, e-bikes, bicycles and some other light electric vehicles.An ebike motor controller is a specific component that connects the electrical parts to make the bike perform better. The device connects things such as display, throttle, motor, pedal assistant, battery, and other sensors. The controller is free now. And then feed the wire that goes to the motor. We have to feed it through the bike's frame. There is a little bit of cable management plastic right there, and you need to push that connector part through the frame, and there is one more zip tie. Some extra zip ties ones in; no harm it, and now, we need to move the other wires out of the way. And then, pull it right through the frame's part it will come out. You will have the controller free of the controller housing and the bike, and then you can replace the controller. Depending on the design of the e-bike, controllers can be mounted outside the e-bike and sometimes placed inside of the bike frame. But generally, all e-bike Controllers are always in an enclosed protective box. This type of controllers is mostly used on small electric vehicles like scooters, electric bicycles, pedelecs, e-bikes, and other light EV.

An e-bike controller is typically located in a controller box, most types of controllers take the battery current energy and direct it to the motor, changing the throttle on a bike allows you to change and manipulate this power in levels of assistance. Where Should The Electric Bike Controller Be? Over-temperature protection. The controller monitors the temperature of the FET( field-effect transistor) and shut down the motor if they become too hot. This protects the FET power transistors. For instance, if the motor voltage has 24V, the controller voltage should have 24V as well. However, if it is a programmable controller, you can limit the extent of power if needed. Besides, the voltage of the controller, motor, and battery should match each other. Because of all this, the controller won't heat and it would perform with stability. As such, it improves the system's reliability. 3. Whether it's a dual-mode controller, non-hall senor, or hall sensor controller If the tester light is flashing, it means it's working. If only the middle light is flashing, it means your controller has a problem. Frequently Asked Questions for Ebike Controller

Functions of E-bike Controllers

Most e-bike controller will have these wires motor, battery, brakes, throttle/ accelerator or PAS Pedal Assist System (some controllers have both types of wires, some have one of them). Hall sensor - If the electric bike motor has a hall sensor then the controller needs to have one too, this allows the motor to have a lower power consumption while maintaining its torque. The wire types and wire terminal(connector) of the e-bike controller could be different in the different controller design. You need the electric bike controller wiring diagram to ensure the right wiring connections. It takes energy from the battery and directs it to the motor. By twisting the throttle, the user can regulate the power that is being sent to the controller, this, in turn, controls the speed of the e-bike. Please, remember, that riding with flat tires puts additional stress on the motor. Do not flatten your tires if you plan to ride on rough terrain. Delfast electric bike: designed to avoid overheating
