A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source. After all of the motor cleaner has leaked out, it is time to let the motor dry. This could be required every 20 minutes of runtime for a fast motor, like a 3000kv 20t. If you want to lubricate the commutator, make sure to use comm drops only. The best way to refresh a commutator is by using a lathe. While your brushed RC motor is disassembled is also a good time to clean it following the above-mentioned steps and check if all the bearings are in good condition and move freely. A comm stick can help, but it cannot substitute a proper lathe cut since commutators will slowly erode and wear out at the area where they make contact with the brushes. Most hobby shops have the necessary tools and can do it for a small fee. Brushed Motor BREAK-IN Tip: For Breaking in a Brushed Motor, Best method is run the motor on low voltage less than 3 volts. Make sure to drive it both forward and backward. (You may have to repeat this step two or three times to ensure quality cleaning.) Just dry run it 30 to 40minutes in the correct direction at 3 to 4.5 volts.There are other methods but you would have to get real friendly with a rc car racer because … Usually it's necessary to "break-in" a new brushed motor so that the flat brushes get a curved surface and thus increasing the contact area with the commutator. Considering there is a good number of... Hi I'm Paul Good. This can either destroy the motor or cause it to lose performance. Hold the motor by the two cables (the flying leads) upside down over the container. Wrap the sandpaper around the commutator and spin the commutator using the rotary tool at very low speeds. The problem with brushed RC motors has always been that they require more rigorous and frequent maintenance and cleaning (compared to brushless motors). Usually, breaking in is more important to brushed motors with hand-wound armatures than to motors with machine-wound armatures. You don’t want to let the water sit inside the motor, as this can lead to corrosion and rusting. Secure Motor Mounting. There maybe a defect from assembly (i.e. Often people think their RC motor has burned out, and they replace it without even knowing that it may have stopped working simply because it has gummed up. we can buy these actuator as itself, but i collect it all from junkyards and scraps. Breaking in a brushed RC motor is not mandatory, but it can give the motor a slight boost in performance and improve the longevity of the brushes and the commutator. Hold the sandpaper and apply light pressure until the commutator has been thoroughly cleaned. This is a fairly easy process, which may require a few basic tools that you probably already have lying around your home. You can use a standard 3-in-1 multi-purpose oil or an electric motor oiler. They will clean the tires, the suspension, and the various electrical components of the RC car. Most people will avoid letting their commutator go below 0.270″ in diameter. After the water break-in process is done, the motor should be thoroughly dried, sprayed with motor cleaner, and the bushings lubricated. The break-in process is needed because it allows the brushes and the commutator to sit properly. They generate more power than brushed motors, and they are very low maintenance. It is considered good practice to break in a new brushed RC motor. The other thing to look for is performance. This article aims to introduce the concept of brushless RC at a basic level, explaining the core differences and offering examples of them in use. You can also take it apart and dry with a towel, then break it in to warm the parts and evaporate remaining dampness. With time and use, dust, sand, and dirt accumulate inside the brushed RC motor, causing it to gradually lose performance and eventually stop working.

Your brushed motor will need brush replacement, it is only a matter of time! When lubricating the motor, make sure only to place one drop of oil near the motor shaft on each side of the motor. Brushed DC Motor Cons Wears Quickly. Comm stands for commutator. This is a method leftover from the racing days of old. You'd have to go a LONG way to convince me that running an oiled electrical device underwater is a good idea. People who own RC cars know that they need to care for them. I just dunked it on a cup of water and hooked up a single AA to it. It is considered good practice to break in a new brushed RC motor. However, a few telltale signs will indicate if a motor is near the end of its life.
