I broke it in exactly as instructed and then ran the new motor again in water using the LiPo pack, but this time under half-throttle. If you have any of the above symptoms, it’s probably time to grab yourself a new motor. A flashlight D-cell battery, 3 or 4 connected in series, would work. By logging into your account, you agree to our. From time to time, you should remove your brushless motor and do some general cleaning and maintaining. A. A brushed motor. i never broke my motors is untill my buddy broke one in for a race, dang it was night and day. I just run my car for 15 minutes at half speed then I squeeze the trigger for a minute. As far as the brushed motor goes, a 3s will almost surely burn up a brushed motor eventually (trust me, I've done it many times. The brushed motors are the original, older style, and the brushless are newer. It shouldn't because the boat is LiPo compatible up to 2S and even recommended. I bet the motor will burn out before a 5000 mah lipo hits lvc. In most cases this is a bearable thing to do if you find the result useful. Do you find this helpful? Does anyone "break in" brushed motors anymore, The following errors occurred with your submission. This one is out of an old Traxxas RC car. he did it in a cup of warm water with c batterys for two hours. The only maintenance I did was lubricating the driveshaft. This is a quicker option if you have bullet connectors. However if you have spent some time soldering your motor connections then this setting quickly becomes your best friend. Brushed motors use a rotating switch called a commutator to periodically reverse the current direction in the coil, switching that side of the armature to attract or repel the fixed magnets in the motor. When I got back I noticed the pack didn't discharge completely. There are two different types of rc motors. On the surface, it is easy to differentiate a brushed motor from its brushless counterpart. Re: Do you have to break in brushless motors? Run it for a couple of minutes. How often you have to do this depends on use. You can use this simple equation with all RC motor sizes. Solder 'em up and let 'em rip! If the carbon (a brush is essentially a carbon block with a metal spring tail) shows any signs of breakage, crumbling, or burning, the brush needs replacing. This is a method leftover from the racing days of old. Motors in electric-powered radio-controlled (RC) cars use one of two types of motors: brushed or brushless. My next vehicle for sure is going to be brushless. Brushed motors run hot naturally, cooling coils only do so much. The "break-in" may be done by running the motor without load (without prop), at about 1/2 its rated voltage for about a hour or two. BRUSHED MOTOR REPLACEMENTS Closed Can-20T Electric Motor- AX24003 27T Electric Motor- AX24004 The above questions need to be answered before picking the correct motor. I see no mention of any maintenance after the 6 runs. DISASSEMBLE THE MOTOR. They consist of stator magnets which are stationary and permanent magnets, and they are mounted inside the shell of the motor. The key point to know is that this was done because it rapidly wore or “seated” hard brushes. If you have any questions, let us know! It uses a brushed dynamite motor. - Motor Timing Explained - If you have a sensored brushless power system, you’ve probably noticed timing marks on the end of the motor’s can. This is where even the less efficient brushless motors still outshine a brushed motor - no "break in", and no ongoing maintenance. This will be mentioned in the respective motor's manual. I was just wondering if my LiPo was burning out the motor. where I = motor initial short circuit braking current (see below) and . A quick and simple way to break in a brushed motor is to put it into a glass of water, and use a low voltage battery. Thank you very much. They also often have vents, since the constant … Some high-quality motors do not need to be "broken-in". The 540 motor is the ideal choice for 2WD RC electric vehicles of 1/12 and 1/10 scale. CW – clock wise rotation. Privacy Statement - I'm awaiting arrival of the Xtreme 180 motors/engines, with silver brushes, any specific notes on these silver ones? I use the manufacturer's marine grease and never over-discharge so I wonder why it gets so hot. Usually, apart from the labels, you will directly know that it’s a brushed motor if it has 2-wires. Sealed endbell motors need a lot of running to break in their hard compound brushes. 4. Brushed motors are longer and more cylindrical, owing to the increased bulk needed by brushed commutator.

First you have to find out what you want. Currently Active Users Viewing This Thread: 1, Painting, Designs, Graphics and Photography, Other Items: For Sale/Trade or Wanted to Buy, Buyer/Seller dispute and discussion forum. All things being equal, a LiPo battery will make a brushed motor get much hotter because a LiPo delivers a lot more current, continuously, than a NiMh battery. #4 Brushless Motors are Smaller and Lighter Another big pro for brushless motors is that they are far smaller and lighter than a brushed motor. A heavy user might want to do this once a month, where a light user can get away with once a year. Brushed motors are cheap but very ineffecient and lact power. As we have already calculated, the current I necessary for a torque of 0.008 Nm is 0.357 A U0 = I x RM + k x ω = 0.357 x 10.2 + 0.0232 x 419 = 13.4 volt BRUSHED MOTOR APPLICATIONS MEDICAL Powered surgical instruments Dental hand tools Infusion, Volumetric & Insulin Pumps Diagnostic & … A lipo battery will provide consistent amps through out the run while a NIMH starts to degrade within a few minutes. Do Not Sell My Personal Information -. To break in my race motors, I run them in a tub of cool tapwater on a 3.3v lead from an old hotwired computer power supply. Powering a small, lightweight on-road car is definitely different from a heavy 1/8 scale off-road buggy or truck. Use of this site indicates your consent to the Terms of Use. Brushed and Brushless. mind, you probably would save money with a brushless motor over time, although they do tend to be a bit more expensive than brushed motors. None to the motor. There's about 800 different ways to do it and they're all wrong. Welcome to model boating and the forums JB. This commutator physically rubs against brushes to make and break the connection required and this is where the name comes from. You actually need to make sure that you have the right amp level for the type of ESC that you have for your vehicle. the only way I know to check brushed or brushless, is to open the motor … It can seem a little intimidating at first, but fret not, it's a simple process. This frustrates me though because it was the replacement motor and I don't want to replace it again. The 6th run, I ran it for less than a minute and it got extremely hot and slowed down. There is a guy over at rcm who is converting a pickup to BL, uses a massive motor and lots of 12v batteries in parrallel- a slow progress project, but when its all finished it'll be awesome. This is something that only applies to brushless motors. R/C car modelers have special transformers for optimum breakin on high performance motors. This is how we used to break in our Neo & Cobalt 700 race motors. For a third opinion.. no, no gentle break-in required. This speeds up the break in process and keeps the motor cool as well. The ESC's are also cheaper. For example, if you have a 14 amp rated vehicle, it will be a good idea to have at least a 15 amp ESC, so that it can deal with the “pull” that the vehicle has. Or just the same as with the carbon ones? Most cars and trucks that fall into this category work best with a standard 540 size electric motor. Cookie Policy - The Horizon Hobby rep told me I needed to break the motor in simply by running it out of water at quarter throttle using the stock 6-cell 2400mah NiMH battery. The brushes should get a curved surface without sparks/arcing. The reason is that 550 motors have too much power and weight for most 2WD setups. For detailed instructions on breaking in your remote control vehicle's engine, watch this RC hobbyest how-to. Do you have to break them in and if so whats the best way to do it? You do not need to unsolder the motor’s power leads or unplug the sensor harness, but doing so will give you more freedom to work. In case of doubt, just break it in. Brushed motors only have a few parts, so let’s talk a bit about each one. But now it's time to talk about sensored vs sensorless. This is only partially true. A brushed motor has 2 wires and you can change the rotation by changing these wires around. Due to their affordability, brushed motors are usually supplied with most entry-level to mid-range radio control car kits. I guess that's just a normal motor temperature. The ESC cuts-off at 3.3v (per cell) but my hobby-grade charger read it discharged to 3.8v (per cell). Running it partially submerged in water helps break them in faster. A little bit of in and out movement is ok, but side to side generally means the bushings have worn out. I took it to my local hobby shop and got the motor replaced under warranty. Terms of Service - Repair an angle grinder that stops working randomly - replace the carbon brushes Hey all, I'm fairly new to te RC Hobby. Electric RC Helis - Brushed Electric Motor Break-In Guide (Not Just For Heli's) - Thanks a lot for this info! I'm definately going to break … DO NOT water break-in your brushed motor! Without an esc, your motor would just do nothing or go full throttle when you wanted to drive. What issue am I experiencing? Hard brush compounds paired with a brush that was not pre-cut like so many are now made this method a way of seating the brushes, "breaking in" the motor. I own a ProBoat Stealthwake 23". Braking power is about I^2R . If you have ever owned a ready-to-run electric rc car, chances are that you would have used a brushed rc motor at some point. Water dipping is a trick old-school guys used to break in their motors, but it would also help clean your brushed motors. a stepper motor will have four leads coming off it, one for each coil 9each coil turns the shaft 90 degs, which is why it is controleabul. Shaft Wobble- Does the motor shaft move side to side? Contact Us - Mark says virtually - not sure why - unless he means geared, in which case gear lubrication is important...a You dont have to, but they generally last a bit longer if you do. Ideally you'd like to run the motor at about 1/3-1/2 it's rated voltage with no load (without prop) for an hour or two—long enough to wear the brushes down without arcing. I have a low-voltage alarm in addition to the cutoff for my LiPo. Archive - Advertising - As a general rule, if either brush has worn to about a quarter inch long, it is time to replace it. Never use this method on brushless motors. CCW counter clock wise rotation. Thanks for the help! The main idea of breaking in your engine is to wear down your engine's brush so as to maximize surface contact with the commutator, reducing resistance (and therefore waste energy) and thereby increasing power. What speed and runtime do you want to achieve? Each motor type has its own kind of ESC (Electronic Speed Controller). It was hot enough that I could only touch it for a half second. They indicate a range of stator/sensor timing that adjusts how the motor’s RPM builds throughout its powerband, and you … If the motor has three wires, then it is brushless. We have talked about Brushed vs Brushless, read it here. After removing the motor, wipe it with a rag to remove dust and dirt. Yes, you do need a brushless ESC for the brushless motor. In order to change over from brushed to brushless, you must first purchase a new brushless motor. This is how I chose to break in my brushed motor using the water break in method. Many RC enthusiasts will point out that old school RC racers used to purposely dunk and run brushed motors in water to break them in for higher performance. This is so that it doesn’t cause any malfunction. Copyright © 2021 MH Sub I, LLC dba Internet Brands. Brief break-in period required for Titan 12T motor Article #542355 The Titan 12T 550 motor will require a short break-in period to ensure optimum performance and longer motor life. Choosing the right, either sensored or sensorless, is important as they both have different qualities and downsides. Driving in something like an empty street or parking lot, slowly rolling in the throttle, no sharp turns, don't touch the brakes or move in reverse, and keep it under 3/4 throttle. R = resistance of circuit formed including motor-rotor resistance + wiring + brush resistance if relevant + any external resistance. Brushless motors have very few parts, so it’s easy to … Like I said, many different opinions here! Dry it off with compressed air, if you have it. Did you at least oil the bearing's? I ran it about 6 times and used a Venom 40c 5000mah 2S Lipo. Brushed motors are great to get you in the door for cheap, and if you’ve never driven a hobby grade RC before then they have more than enough speed and power for the first time driver, but once you get the hang of driving, you’re going to want more power. Well, we have talked about KV, check it out here. but i would only do this for racing, Yup, breaking in a motor is just like NiCd/NiMH battery maintenance and the correct way to shut off a nitro engine. It should also be noted that brushless motors do not really require a break-in because they do not have brushes, and instead work on FM (frequency modulation, a type of a/c power), and brushed motors work on current regulation through voltage (current is directly correlated with voltage, if the resistance stays the same, and the voltage goes up, then the current will go up also). Our motors …
