Can You Use A Sensored ESC With A Sensorless Motor?

When it comes to any motor, the ESC has the most crucial role to play. The Electronic Speed Controller (ESC) controls the speed of an electric motor and also applicable for radio-controlled models. But sometimes, people use a different ESC with another different motor that is not even designed for it.

You might ask, would it not be a problem then? Well, in this article, we are going to discuss the question, which is- can you use a sensored ESC with a sensorless motor?

Can You Use A Sensored ESC With A Sensorless Motor?

If you are interested in finding the answer, then read the article till the end. Before that, you have to know a bit about ESC and its function in motors.

The ESC (Electronic Speed Controller)

Mainly, it is an electric circuit that gives a command to the motor by altering the frequencies. The rapid switching of frequencies of transistors causes the motors to increase the speed or reduce it. They are used in brushless motors because of their power, efficiency, synchronization, and longevity. The back Electro-motive Force (EMF) is detected by motor rotation which is accounted for by ESC. Hence, you get the idea about ESC, right?

Can You Use a Sensored ESC With a Sensorless Motor?

Yes, you can do that. Many people do not refer to use a sensored ESC in a sensorless motor. The logical theory behind it is that ESCs are built for such kind of brushless motors. Then why can’t you use them with other brushless motors?

The view is not illogical, and most of the time, the motors run well if you do the replacement. But you might face some downsides after that. Sometimes it would not even work. Therefore, you have to run a double if you are serious about it.

Compatibility Would Be a Problem!!!

The compatibility will not be a more significant issue in using a Sensored ESC in a sensorless motor. That is because both of them brushless motors. They run the machine quite a similar way. Therefore, the primary function of the ESC remains the same for both sensored and sensorless motors.

But there will be some problems. It is because some ESC is programmed to do a specific job. If you change a sensored ESC, it might not adjust with the new one. Then any performance will not be expected from that motor.

What could be the Problems?

Suppose the ESC you replaced is not working. Then how do you know the problem and what could be a problem? Let us show you some of the problems you might face while doing it.

Shape and Size

It is a fact to worry about the shapes and sizes. That is because all the machine chassis comes in different spaces. You might face some problems when you try to fit any other ESCs. On the other hand, sensored ESCs have options to manage the setting in different intervals. You might not get that option on a sensorless motor.  

Powering Up

The ESC is considered as master power button of any machine. Any mess up with it might lead you to the struggle of powering up your vehicle. A Sensored motor needs higher power to start. But a sensorless motor needs minimal power. When you replace the ESC on a sensorless motor, the motor will get started. But over-power might be a problem to start up the vehicle.


The ESC also controls the power flow from the motor. When the power coming from the battery is too low, it will reduce it or cut off the motor’s power. Even if the power is excess regarding the motor, the circuit will break automatically.

Wiring Plugs

Most of the wiring plugs are very similar when it comes to ESC. But there is a difference in wire looming. The sensored ESC needs a dense wire looming while a sensorless motor has insufficient space for that. Therefore, it could be a problem if you use another ESC.

Loose Speed

You might know that sensored motors can produce an incredible amount of torque from zero RPM. In sensorless motors, it will not happen. Besides, the speed would be lost. You will lose the boost and turbo. 

Power Consumption

If you place a sensored ESC with a sensorless motor, you will need more power to run it. That is because ESC of sensored is made for greater power to use. It is because it needs to acquire higher torque from zero RPM. When you place the ESC in sensorless motors, you will need extra power from the battery.

Hybrid could be An Option!

A hybrid ESC can be used as an alternative. But it should be programmable. The main advantage of a programmable is that you can use it according to your wish. You just have to install a program for sensorless motor. Then, it will run like usual.

When you use a hybrid ESC, you will not face the problems we discussed in the article. Clogging is a problem for sensored motors. By using a hybrid ESC, you will have less clogging compared to regular ones.

Even you will not face any powering up problem along with other issues like it. But it will be a little bit costly compared to a regular one.

Some Tips

First of all, using a sensored ESC into another motor is not a huge problem. But there is a possibility to face problems, right? Then, it would be best if you avoid such replacements. Suppose you have set your mind to change the ESC to a sensorless motor. Then double-check the circuits and wires is a must for you. Therefore, you should use the ESC, which is compatible with your motor.

Bottom Line

An ESC is the key feature of any electric motor. But your question was, “can you use a sensored ESC with a sensorless motor? We hope the article has enough points to answer the question. Therefore, it would be best to choose if you are sure about the facts we have discussed.
