How to Test a Speed Controller for a Brushless Motor
May 15, · Esc Brushless Motor Combo – Matching The ESC. How to match an Esc to your RC Vehicles Motor? You need to start by knowing your Vehicles Motor KV rating and dimension, As well as the wattage. You can find this information in the instruction manual for your model or . Mar 03, · The main brushless motor is not as powerful as before and I have to apply 75% throttle to keep hovering above the ground. It used to hover with 55% throttle at the same altitude. I don't know whether it is the motor or the ESC that causes the problem but since the ESC is located between battery and the main board, it was probably pressed.
Think twice before making your car NEED to have a reverse rotation motor. This discussion is for all types of RC brushless motors. The older brushed-type motors will be discussed in another post. The need to reverse rotation in brushless motors comes up every so often and I have to engage my brain for a while to make sure I have explained every detail to the customer to prevent fried motors and other pitfalls if you REALLY want to do this. I consolidated all this research in this blog.
Best method is to have a car setup for standard motor rotation, you will be happy you did! Simply change that option. With the motor rotating in what is chan gailey salary, the markings on the motor have a new meaning. The '60' mark is now ZERO, the '30' mark is still 30 degrees, and the ' 0' mark is now 60 degrees.
If we do not properly set the timing again, the motor will run hot, have low power and sound funny when running. To set timing, move the pointer to '30' in the picture above by loosening the three screws with a 1.
Then use your ESC options to set the timing to your preferred setting; more turbo and boost will work correctly when you use your ESC set to reverse rotation. You did also set the rotation to reverse in the ESC too as in step 1, right?
Rotate the pointer to 30 degrees for safety. Remember, if you want MORE timing the numbers will become smaller. For example, with a motor reversed, the '20' mark on the motor is 40 degrees see above. Use your track testing for final setting and monitor motor temperature closely. You may still reverse the rotation but read what I say twice before you do it, as your motor will be very unhappy if you do it wrong and possibly suffer ESC damage! We are talking about sensored brushless motors in this section, just to be clear.
Then adjust timing as shown in step 2 above. Just added to your cart. Continue shopping. Close search. First we need to identify the type of brushless motor. There are two types: 1 sensored and 2 unsensored. Of the two, the sensored motor is the most common now. The sensor port is the black rectangle in the how to fix ps3 network connection below there are six pin connectors inside the rectangle.
There may be two ports on a motor. A nonsensored motor does not have any of these ports on the motor. The brass colored connectors with solder on them at the top of the connector is the motor connection 37 weeks 3 days pregnant what to expect. Reverse Rotation For Sensored Motors:.
Unsensored Brushless Motors:. Since you want reverse rotation, and most motors are set for normal forward rotation clockwise from the timing, non-shaft endyou will need to reset timing also. Use step 2 under the 'Sensored' above for your options. Many radios have his option also, but you still must alter the timing as mentioned in item 2 above under "For Sensored Motors".

With this, the ESC provides regulated 5V which can be used to power our Arduino. We can notice here that this connection is actually the same as the one we see on Servo motors. So, controlling a brushless motor using ESC and Arduino is as simple as controlling servo using Arduino. ESCs use the same type of control signal as servo and that’s. Sep 03, · KV rating for brushless motors and matching with the right ESC I've been planning on a tacon from hobbypartz because I've heard good news from them and stick with an ezrun ESC. Problem is I don't understand the differences in the KV rating and how to match it up with the right ESC. Easy, follow this: FIRST, always follow amperage ratings of motor under load. Prop loads will have to be taken in to account, most of this data is available out there. I tend to use my own method for figuring that bit out in my head, please don't.
Which motor combo is right for you will depend on the RC car and type of driving you to want to do. Before you buy your Brushless Motor Combo make sure you know your RC car and how you will be running it, What kV rating, wattage, amperage and with what battery do you want to use. These are all things you need to know. Check out my RC Motors page to find your next motor.
Things you need to know about getting a brushless motor combo for your RC car. You need to know the kV rating, wattage, amperage and the dimensions of your models motor. The higher the KV rating means higher top speed but lower torque. When you have lower the KV rating means higher torque but lower top speed.
You can find this information in the instruction manual for your model or on vehicle packaging. The next thing you want to know is the motor amperage. Say your motor wattage is and your battery is a 3 cell lipo In this case, you will want to get an ESC that has an amp rating of at least 45amps. The higher the ESC amps the better, so higher amps than both the battery and motor rating is great, You never want to go less amps than the motor is rated for, This can cause overheating issues and not get the full performance from your motor.
This is also true for your battery. The battery pack amps should be higher than the motor amps. To Find the amperage of your battery take the milliamps mah and the C rating of the battery and multiply them and then divide by This gives you the amperage that can safely be pulled from the battery.
That battery has an amperage rating of amps. Just remember the bigger the battery the heavier the battery will be. The heavier the battery is, the less top speed your car will have due to weight. That is why it is best to find a battery that is higher than but close to your motor amp rating, This will give you the lightest option for your battery. When looking at a brushless motor combo keep in mind what you want your RC to be able to accomplish. High top speed or high low-end torque.
Maybe you want something in the middle, Then you should be looking for kV rating of around kv. Having an RC vehicle that goes higher top speed is great, However, you will lose some low-end torque which effects the takeoff acceleration. One thing you should be aware of when getting a brushless motor ESC combo. There is a lot of misleading information on getting more power out of your RC Car with using a bigger battery.
Therefore if you are using the right size battery, then switching to a bigger battery will NOT give you more power. The motor will only pull and use as much energy as it is intended to use. Even if you have more power available then the motor is rated for, the motor still will only use what it needs and is able to use, no more. Using a battery that does not have enough power amps for your Esc brushless motor combo will hold the motor and ESC back, Not letting them operate at there fullest.
Which can result in overheating and or burned up ESC? Ultimately could cost you a lot of unnecessary money. This will save you money and time by avoiding broken or fried parts due to trial and error.
Please let me know your thoughts and opinions. Thank you. Great information here. I recently fried my esc on my short course truck. I been looking for a good motor esc combo to put in it rather than just switch the esc. I did not know what to get or even how to find out what motor and esc would work. Now after reading this article, I feel confident that I can get a great motor esc combo for my RC. Thank you so much.
