Features to Look for Before Buying
Before making a purchase, take a look at these specifications to help you determine the best brushless RC motor for your car or quadcopter.
The KV rating is represented by the number of revolutions per minute that the motor delivers when voltage is applied. In addition to that, there should be no load attached.
If speed is your priority, choose a motor with a higher KV for faster rotation. One more thing that you should be aware of is that the motor's KV is constant, whereas the RPM is variable. This means that when you change the voltage, the RPM also changes.
When you are comparing motors, it is best to look at the KV more than the RPM.
Always watch out for the wattage rating. It indicates the rate at which your motor draws electrical energy from the battery to convert it into mechanical energy and heat. With this, you have to consider the efficiency and heat generated.
Since wattage is used to rate the motor power, remember that it must not exceed the maximum to prevent working the motor too hard.
This control allows you to precisely regulate the speed of an electric motor. Electronic speed control, or ESC, is the common electronic circuit used for brushless motors. This enables you to reverse the motor and allow dynamic braking.
Sensored and Sensorless
The only difference between the sensor system and the sensorless system is their precision of transmitting data to the speed control.
An advantage that sensor systems present is the accuracy of their response to all speed changes, whereas sensorless motors are merely able to estimate the rotor position. With that in mind, it is only estimating whether it is delivering the right speed.
When it comes to amperage, you should be aware that exceeding the amp rating of a brushless RC motor poses the risk of overheating. Not even the best brushless motors can handle such an increased rated amperage.
Since amperage refers to the maximum current flow that the motor draws, choose a motor that has a rating that suits your application for it.
For instance, a motor with 300W and a maximum voltage of 11.1 should have a rated amperage of 27.03. How did we arrive at that answer? Simply divide the wattage by the voltage.
This amp rating tells you that the ESC you choose for your motor must have a rating higher than 27.03A. If your ESC has a lower amp rating, it will hold back the maximum potential of your motor.
The efficiency rating is the one that you see with a percentage (%) label. This entails the ratio of how much of the motor’s electrical input power has the capacity to convert into mechanical output power. Aside from that, it also displays the amount of energy lost in the form of heat.
And the less efficient a motor is, the greater the heat is produced. With this, the motor is at risk of damage in its parts, which greatly reduces performance.
Frequently Asked Questions
How long will brushless RC motors last?
Brushless motors, in general, have a long life expectancy. The best brushless RC motors should last tens of thousands of hours on average. This is because there are no brushes that wear out, unlike the brushed motors that can only last up to a thousand to three thousand hours.
How fast can a brushless motor go?
To see how fast your brushless motor can go, simply multiply the KV rating with the voltage of the power source. For instance, the best 380 brushless motors with 4800KV powered by at least 11.1V should spin at 53,280 RPMs with no load.
Take note that an increase in the voltage will change the RPM. This requires a change in the propeller to avoid overloading the motor.
How do you test a brushless motor?
If your motor is spinning but constantly overheats, you can run a dry test to understand the issue. Simply disconnect the motor from the electronic speed controller and wind it up using a variable speed drill.
Run it at full speed for a couple of minutes until you hear a strange noise or the motor gets heated. If this happens, it means the winding is shorted, or there must be a loose magnet.
Aside from that, you can use a voltmeter to know if your motor wires have problems. Otherwise, if the meter does not read an open circuit, your motor is broken.
Can you run LiPo batteries on brushed motors?
Given that you are going to use 2-cell LiPo batteries that match the right ESC, then the answer is a yes. You can use that kind of battery on the best RC brushed motor and feel a little boost using them more than NiMH packs.
Make sure you have the LVC on the speed control turned on to watch over the voltage being delivered by the battery.
One of the most important features to look at when buying is the standard ratings to ensure you are obtaining the right components and make the engine work.
Clearly, the best brushless RC motor means the right KV rating with the required power supply or voltage, as well as the suitable ESC. There is no one perfect product for a particular vehicle. It depends on the capacity of your RC vehicle as well as your personal preferences.
