Dual-mode electric bicycle controller

Dual-mode electric bicycle controller

Electric bicycles are rapidly becoming more and more popular and popular in the modern world. As more and more people invest in electric bicycles, technology continues to advance, and more and more types of products are available.

The wide variety of electric bicycle equipment on the market has caused many people to have questions about the specific component of the dual-mode electric bicycle controller. What are these controllers and do you need one?

The dual-mode electric bicycle controller receives signals from Hall sensors and non-Hall sensors. Even if the non-Hall sensor fails, the electric bicycle dual-mode controller will usually continue to induce the motor to rotate. Therefore, unlike a single-mode controller, the motor will continue to work.

There are many types of electric bicycle controllers, one of which has caused extensive discussion is the dual-mode controller. There is very little comprehensive information about the hardware of this electric bike, so it’s time to clarify the subject.

Read on and I will help you understand what a dual-mode electric bike controller is and whether you need one.

What is a dual-mode electric bicycle controller?

In the world of electric bicycles, there are usually two types of controllers to control all electronic components including motors. One of the most popular is a relatively new electric bike controller called dual mode.

The dual-mode electric bicycle controller can operate normally on motors with and without Hall sensors. If the controller does not support dual mode, it can only operate normally with or without Hall sensors respectively.

This is a key function of modern electric bicycle controllers. If the electric bicycle motor is equipped with Hall sensors, like most brushless DC motors, and the controller installed on the electric bicycle requires these sensors to work, then if the sensor signal fails, the motor will fail. This is likely to happen in due course.

Conversely, if the motor in an electric bicycle is designed without Hall sensors, like most brushed motors, the situation will be very different. If the controller needs to be replaced and a motor that requires a Hall sensor is installed, the controller will not be able to control the motor at all.

Specifically, the dual-mode controller is suitable for two types of electric bicycle motors, regardless of whether they are equipped with Hall sensor drives.

If your e-bike is equipped with a motor with Hall-effect sensors, it is ideal to install one on your e-bike, as these sensors are very sensitive and may be damaged or malfunction. If a fault occurs, the controller will continue to run and effectively control the motor.

If you want to modify an electric bicycle, the best way is to make a bicycle with a motor with Hall sensors and add a compatible controller.

What is the Hall effect?

Brushless DC motors for electric bicycles often mention the Hall effect, and we know that this is an important factor to consider. But few of us fully understand it and why it is important for electric bicycles.

The Hall effect is essentially how current affects the magnetic field. Measuring this effect is an excellent method of detecting current differences, and an efficient method of detecting and correcting changes in the current source.

Of course, this is a very simple explanation, but it helps answer this question because the Hall effect is related to electric bicycles.

Why is the Hall effect important for electric bicycles?
The Hall effect is very important because it is a very effective means of measuring the position of the brushless motor, so that the electric bicycle controller can effectively adjust the power at the perfect moment to make full use of the motor’s capacity.

Hall-effect sensors are so small that they can even be installed in the smallest electric bicycle motors. Using these sensors to accurately detect the position of the motor at any given moment is the most effective way to utilize the available energy of the motor.

The effective use of this energy prolongs the expected life of the motor, extends the battery life by reducing battery consumption, and provides more power from the motor, because the motor can be fully utilized without causing unnecessary power loss.

Hall-effect sensors use magnets to detect current changes through the motor and transmit this information to the electric bicycle controller. Then it can make appropriate adjustments to the operating mode of the motor to maximize the efficiency of the motor.

For this reason, the Hall effect is very important for electric bicycles. If this electrical detection method is not used, electric bicycles will not be as fast, powerful or efficient as they are today.

Do all electric bike controllers have Hall sensors?

Hall sensor is an important innovation in electric bicycle technology. These sensors enable electric bicycle motors to be used more effectively, thereby making electric bicycles more powerful and practical. But do they all have these sensors?

Not all electric bicycle controllers have the ability to receive information from Hall sensors, and not all electric bicycle motors are equipped with these functions. Modern brushless motors used in electric bicycles usually have Hall sensors, while standard brushed motors do not.

The use of this type of sensor in an electric bicycle drive system is not always standard. Before using these sensors, there are other more ineffective methods to adjust the power of the motor and control the effect of its use. But none of them are as accurate as Hall-effect sensors.

Some electric bicycles are not equipped with these sensors, simply because they are not necessary. Many pedal-assisted electric bicycles do not require such complicated motor management and control, so there are only non-Hall sensors.

However, those equipped with these two sensors are more efficient, more powerful, and more effective than those that do not.

Why do electric bike controllers need dual-mode?

The dual-mode controller is optional for electric bicycles and is not always necessary. Why do some electric bicycles need these controllers while others do not, and what makes them so important?

Dual mode is a name that describes the ability of an electric bicycle controller to operate with or without Hall sensor drive to manage the efficiency of the electric motor in the electric bicycle. This is necessary to prevent the sensor in the motor from malfunctioning and to provide a somewhat general electric bike controller.

The ability of an electric bicycle controller to function as well as the motor used to control is essential for the operation of the bicycle’s electrical components. If the electric bicycle is equipped with Hall sensors and these sensors fail, the standard controller will also fail.

However, if the same electric bicycle is equipped with a dual-mode controller and the Hall sensor fails, the controller will continue to work. The function of the controller will be limited, and the system will not be so efficient, but the electric bicycle will continue to run without stopping.

These types of motors are necessary to maintain the function of an electric bicycle equipped with a Hall-effect sensor when the sensor fails. As we all know, these sensors are very fragile and are likely to break over time, even with minor accidents or bumps.

If the controller is affected by this, the electric bicycle will not be able to run.

Another important reason for the need for dual-mode electric bicycle controllers is that they can give full play to the potential of motors and electrical systems.

Without this type of controller, any complex electric bicycle will reduce performance and power capabilities.

How to damage the Hall effect sensor?

As we all know, Hall effect sensors can fail. This is why there are dual-mode controllers…but what makes this type of sensor so prone to failure?

These sensors are nothing more than small magnets connected to electrical circuits. They are effective because they are fragile. If they are more powerful, they will not be as effective in detecting the current difference from the motor.

The sophisticated nature of Hall-effect sensors means that they can fail due to excessive pushing, power surges, and even wear.

This means that they are also likely to break faster than other components in the electric bicycle electronic system. A big bump or a small accident may cause the Hall sensor signal to be damaged.

This is also true for surges caused by incorrect disconnection of the battery or even due to overcharging of the battery. These sensors also wear out over time.

For these reasons, an electric bicycle equipped with a Hall-effect sensor must be equipped with a dual-mode controller so that the bicycle can still work normally when the sensor fails.

Hall effect comparison Non-Hall effect motor
When discussing dual-mode electric bike controllers and their uses, it is important to understand the motors that such controllers are designed to work with. Finally, the dual-mode electric bicycle controller is designed to work with motors that utilize Hall sensor signals.

A motor equipped with a Hall sensor driver can detect the position of the motor very accurately and send the information to the controller. Non-Hall sensor motors do not have these sensors, so they are not controllable.

Hall effect motor

The dual-mode electric bicycle controller is designed for use with Hall induction motors. These controllers are more complex and provide a higher level of control for more complex motors.

Motors without Hall-effect sensors only need to use a single-mode controller. The degree of control of these motors cannot be the same as that of motors with Hall-effect sensors.

The dual-mode controller, usually used in combination with a motor equipped with a Hall-effect sensor, can control the motor even if the sensor signal fails.

This is important because motors equipped with these sensors are likely to have component failures at some point in their working life. This is the biggest disadvantage of using this motor.

Non-Hall Effect Motor

A motor without a Hall-effect sensor is unlikely to have component failures unless the motor is damaged. For this reason, these motors can use more standard and less complex controllers.

The controllability of a bicycle motor that is not equipped with a Hall-effect sensor is poor, because there are fewer methods to control the motor due to the lack of measurement values obtained from the motor to send to the electric bicycle controller.

This means that compared with motors equipped with Hall-effect sensors, these motors have much lower power, much lower efficiency, and much less practicality.

However, less complex motors are generally more reliable and robust. These motors are unlikely to be damaged, so they are very suitable for stronger or off-road electric bicycles, such as electric mountain bikes and fat tire electric bicycles.

In general, motors with Hall-effect sensors are stronger, more useful, and more efficient than motors without these sensors. This is simply because more information is sent to the electric bicycle controller to enable it to use the motor’s functions more accurately and make adjustments while the motor is running.

Dual-mode comparison Single-mode electric bicycle controller: advantages and disadvantages
The dual-mode controller can be used for motors with and without Hall sensors. These motors are versatile and they are more accurate controllers, but there are some disadvantages to using this type of controller.

Single-mode controllers are another option. These are not too complicated, but they have some advantages that dual-mode controllers do not.

Before making an electric bike modification, you should understand these advantages and disadvantages so that you can buy the right parts. You can find more information in my article on conversion kits.

Let us compare the two types of motors and weigh their advantages and disadvantages in order to better understand which motor is best under which circumstances.
