Brushed vs Brushless RC Motor

Brushed vs Brushless RC Motor


We’ll be talking about brushed versus brushless  RC motor and how you can use them to your advantage in all sorts of scalars trail rigs and crawlers.

The two most common types of DC motors are known as brush DC(BDC) and brushless DC (BLDC). Although the underlying materials are the same, their construction, performance characteristics and means of control are very different.

Brushed DC(BDC):  A brushed DC motor consist of wound armature, commutator, brushes and permanent magnet.


Brushless DC(BLDC): A brushless DC motor consist of hall effect sensor, stator, rotor and permanent magnet.

Brushed  RC motors advantage and disadvantage

First, let’s start with the good of brushed motors because they have fantastic low-speed control. When you’re going through a tight technical section or maybe a rock that is very difficult in off-camber.

You can ensure that you give through without upsetting your rig and falling off the object. When you’re using a brushed motor, they’re also very affordable in most cases. They’re direct replacements for your stock motor but you can get a much higher quality motor.

They’ll drop in with maybe soldering on some leads and then plugging. The bullets right into your existing motor speed controller brush Motors offer excellent low-speed torque as well and combined with the lowest speed control.

 You can get through some situations that you won’t be able to get through with most brushless motors. They’re also highly configurable so you can put a different armature in there change out—your hood colors to something that you like.

Better and also ensure that you get the exact speed of the motor that you want for the voltage that you use now. On the bad side of the brushed motor, they do have lower power than brushless and mostly because of the brushes themselves, not only do they wear out and so.

You may need a seasonal replacement or repair of the motor but they also drop some voltage. Whenever they’re in a bind, so that does make the motor less efficient. Overall, because of the slightly lower efficiency and the added weight of the brushes.

The brush hoods and other accouterments that you need they do have a higher weight for the same power as compared to a brushless motor.

Brushless RC motor Advantage and disadvantage

Now for brushless motors, they do have some excellent points to them. They have a much longer lifespan since there are no brushes to wear out, you have no maintenance except for the bearings.

You may need to lubricate occasionally the bearings to ensure that they run smoothly. But we’ve had brushless motors and rigs going on five-six years that require nothing except for the occasional bearing lubrication.


So this gives you a better long-term value for your dollar. Along with the higher efficiency and no brushes, you more power out for the same weight of the motor and if you’re looking for a rig that is very capable in terms of speed or power.


 Overall brushless is probably going to be the better bet for you in terms of the wheel speed and top-end power. The brushless motor offers a much-improved feel over brushed motor and again for the same amount of power out.


 You can use a lighter motor and this can improve the handling capabilities of your rigs, especially at high speed. Now the downside of brushless motors is that your low-speed control is generally lacking even Censored motors can have lurching.


 When they start up at first and so compared to brushed motors, it makes it much more difficult to drive through technical sections and keep an exact bead on. Where your rig is going and what it’s going to do and react to the situation.


 Now depending on your use, we do have specific recommendations, if you’re going to be crawling, let’s say eight miles an hour tops a brushed motor is more than likely your best bet.


 Now, if you’re doing general trail riding say 15 miles an hour tops. If you’re looking for speed and efficiency, the brushless is the better way to go. Typically, you’ll get longer run times. You won’t have to repair your motor every couple of runs and in general, it’s a much more pleasurable experience.

 But if you want to focus on more precise crawling with the occasional speed burst, the brush motor will give you that better feel that you’re looking for now.


 If you’re a high-speed enthusiasm mile an hour and more at these high speeds. brush wear becomes extremely fast and it does take a lot of care to keep a brushed motor even running, so because of this brushless is usually the first choice.
