“Oh God, the motor’s worn out again. I could’ve sworn it worked fine last week”. Well, these sorts of problems are fairly common when it comes to brushed motors.
As the name suggests a brushed motor contains “brushes”. These are essentially carbon contact points that allow the flow of electricity through conduction. The main purpose of this is to connect the stationary wires with the rotating wire of the motor.
Now, if your contact points are compromised, you can’t operate your motor. This is an issue that has to be rectified ASAP.
So, how do you solve this problem? That’s where our post on the best 550 brushed motor comes in.
Having the right tool for the job would ensure top performance every time.
But how do we know for sure that’ll work for you. That’s where our research team comes in. They’ve spent hours scouring the net for worthy candidates for this list. This is the fruit of their labor.
In addition to the top 5 list of the best-brushed motors, we’ve even added a buying guide. This will show you what to watch out for before buying one.

In second place we have Globact’s 12T Brushed Motor. Globact has come up with some stunning products over the years. This is no different, so let’s look at the features that earned it the second spot, shall we?
For starters, the Globlact has high vehicle compatibility as it can fit in a lot of RC vehicles. It’s also very easy to install and lasts very long. Like its predecessor, it has an inbuilt cooling fan too.
It has a voltage rating of 6-8.4V. Its recommended that you don’t exceed this level, otherwise you risk damaging the motor.
Its RPM rating for the no-load, max efficiency, and max horsepower is 22500, 18800, and 125500 respectively.
However, it has lower torque and a lower turn rating than the INJORA, which is why it got bumped down the list.
- Easy to install
- Highly durable and weather-resistant
- Compatible with a lot of RC vehicles
- High RPM rating
- Low-torque makes it less powerful
Next, we have a VRC Hobbies Apex brushed motor. The Apex 27T ends the coveted top 3 of our list by coming in third. So, let’s see why the Apex is worth every penny, shall we?
The Apex motor has a dual bushing that ensures that the motor is always in contact with the flow of electricity. This makes it one of the most efficient motors of the bunch as it can utilize power the best.
This is also a fairly powerful motor as it has 27T. This means it has more torque for its size than even the Goblact and INJORA. However, this comes at the cost of it being a bit slow.
The Apex also comes with pre-installed motor capacitors and extra motor connectors too!
It also boasts being able to fit in most 1:10 modeled cars and trucks. This is a plus point given how it’s one of the inexpensive ones of the bunch.
- Decent durability
- Very versatile motor fits in most 1/10 models
- Has low rpm and is slow
- Runs very hot
Coming in at fourth place is Goolsky’s 35T brushed motor. Now, this is an interesting one. But in the end, we had no option but to include it in our top five list of brushed 550 motors.
The Goolsky is the lightest on the list. This makes it an ideal motor for racing tracks, as this adds the least amount of weight to the vehicle.
It also has the highest turn rating of the bunch, which measures at 35T. This means it has one of the best torques as a brushed motor.
However, this comes at the price of it being the slowest motor. It has a max RPM of 9500.
The Surpass Hobby’s maximum voltage rating is around 7.4V and runs at an optimum of 20 Amps.
- Has a massive capacity of 8000 mAh
- This battery generates a punchy power due to high voltage
- Comes with two battery packs
- Offers good high-speed and offroad runs
- Too much heat can damage the battery
Last but not least, we have the Traxxas 12T brushed motor. Traxxas is a pretty well-known brand and it’s not a surprise that this snatches the last place on the list. So what earned it the last spot on our coveted list?
The Traxxas 12T is the heaviest of the bunch. This makes it a bit bulky for more vehicles. However, it is the most compact brushed motor out there. This makes the Traxxas compatible with a lot of vehicles as it doesn’t take up much space.
It has a turn rating of 12T which is one of the lowest on the list. This means it sacrificed its torque for its speed.
It has a maximum voltage of 8.4V which is also higher than some of the others on the list. This means it can run safely under high voltages.
It also comes with new accessories such as a 19T pinion gear wheel and its screw set. If you’re into DIY projects then this is the perfect motor for you, that you can put together.
- Decent durability
- Produces high RPM
- Comes with an accessory kit
- Easiest to install as its compact
- Will add a lot of weight to your vehicle
- Low Torque
Even if you’re an RC crawler fanatic, chances are you don’t know much about servos. Servos are often of the most critical components that are overlooked when it comes to performance.
This is why it’s important to know which factors are important in a Servo’s Performance.
Brushed Motor Size Ratings: Difference Between 550 & 540
One of the most notable aspects that are visible on a brushed motor is the 3-digit number on it. For example, all the motors mentioned above have a 550 rating on them.
So what does this rating mean? This denotes the size of the motor. More precisely the size of the metal can.
In laymen’s terms the higher the number the bigger the size of the can.
Similarly, the difference between a 550 brushed motor and a 540 motor is that the 550-rated motor is bigger. It is a centimeter longer than a 540 brushed motor. Although, it’s important to note that the diameter of the motors is the same.
The size rating is proportional to the torque but inversely proportional to the motor’s rpm. This means that the 550 motors will have a higher torque compared to an identical 540 motor. But this also means that the 550 motors will have less torque than the 540.
This is because the longer the length of the armature, the higher the number of wires wrapped around it. More wires mean more torque.
Voltage Rating: What It Entails
Now, a common misconception that people have about voltage is that it equates to power. The common assumption is that the higher the voltage rating the more powerful a motor is. However, this isn’t the case.
A DC motor’s voltage rating specifies the most efficient voltage while it is running. The torque increases as the voltage rises.
It is recommended you always use the specified voltage. The motor will not run if you apply too few volts, but too many volts can short the windings. This will result in power loss or full damage.
So if you have a voltage rating of 6-8.4V, you shouldn’t go on either side of the values. It is strongly advised you do not exceed the maximum voltage rating as it will damage the motor itself.
Torque Rating: What Does It Mean?
Torque is the rotational force a motor produces. The torque from a DC brushed motor is limited. It is very good for low speed but not that good for high speed.
Torque must also take into account operating and stall values. The operating torque of a motor is the torque it was designed to produce, while stall torque is the torque produced when power is supplied from stall speed.
Turn Rating & RPM On Motors: What Does It Mean?
Another rating that you commonly have on brushed motors is its turn rating or T. This is important to consider while buying any good-quality brushed motors. The turn rating is essentially the number of wires wrapped around the motor.
This works in conjunction with another attribute of the brushed motor: its speed or RPM (rotations per minute). Their relationship is inverse in nature.
A higher T value will result in a slower motor but higher torque. This is because having more wires creates more resistance.
For example, a 21T motor will have higher torque than a 16T motor. But the 16T motor will be faster than a 21T motor.
Question: Are all motors that have DC supply, brushed motors?
Answer: Not necessarily no. There are mainly two types of DC or Direct Current Motors. There are brushless or more commonly known as BLDC (Brushless DC) motors and brushed motors. Both of these have a direct current supply, but as per their name, one motor has a brush that commutates the motor for rotation. And the other doesn’t.
Question: Is it possible for my Tesla Motor to be brushed?
Answer: No, your Tesla vehicle can’t have a brushed motor. Nowadays, almost all hybrid vehicles contain a brushless DC motor. This is because of the numerous benefits a brushless motor has over a brushed motor.
Question: What are the benefits of using a brushed motor over a brushless one?
Answer: Brushed motors have increased torque and a wider range of speed. They are also more efficient and compact. They operate very smoothly at low speeds and have excellent speed control.
Well, this was all we had on the best 550 brushed motor after hours of research. Hopefully, you’ve already found the perfect fit for your needs regarding this issue. If you’re one of the indecisive ones, then pick our top pick.
