What Brushless Motor For Rc Car

Jika anda sedang mencari What Brushless Motor For Rc Car, anda berada di tempat yang tepat! Disini saya akan mencoba membahas beberapa pertanyaan mengenai What Brushless Motor For Rc Car.

How do I choose a RC brushless motor?

The physical size of a particular brushless motor is usually indicated by a number that looks like this – ’22-05′. The first number, 22, indicates how wide the motor is whilst the second number, 05, indicates the hight. Usually, these are written on the motor casing themselves to show you how wide and high they are.

What motor should I use for RC car?

What’s perhaps still the most common motor size used in RC cars, is often called “540”. These are used in many lighter 1/10 cars, while larger “550” or “1/8” sized motors are often used in heavier 1/10 vehicles and 1/8 scale cars. Brushless motors in this size are today often “4-pole” motors.

What is the fastest brushless motor for RC car?

“The Traxxas XO-1 is the fastest RC car, full stop. The largest brushless motor on offer propels the car from 1 to 60 in 2.5 seconds. Not only is this car stylish, but it also reaches speeds over 100 miles per hour.”

What does the KV mean on a brushless RC motor?

Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor. If Kv is like horsepower, then Turns is the physical attribute of a motor.

Can you use any motor with any ESC?

Short answer is no. Not all brushless esc’s are compatible with all brushless motors.

How do I choose a KV motor?

Choosing the correct KV is very important, it’s critical for the motor operation and high motor performance which is critical for the project. There are few things that determine the top speed: Battery voltage, gear ratio (if any), wheel size ( if any) and the motor KV.

What is the fastest 540 brushless motor?

RE: fastest brushless motor 3.5r Novak or 5700 Mamba on 3s li-po are probably the fastest 540 sized brushless with a practical number of cells and not something ridiculous like 16-20 cells.

Is 30 mph fast for an RC car?

The Altair Power Pro 4×4 can reach speeds up to 30 MPH! With the included 2 Speed Settings a beginner will be able to have as much fun as an RC Truck expert! Kick the Power Pro into high speed once you get the hang of how it handles and then you can experience this extremely fast and powerful RC Truck.

What is the most powerful RC brushless motor?

What is the most powerful RC motor? The MGM Losi 5-T brushless motor is regarded as the most powerful RC motor. The model comes with soldered battery, PC cables and motor connectors for providing very high power.

What size is a 540 brushless motor?

540 has a diameter of 36mm.

What is the difference between a 540 and 550 motor?

The difference between a 540 and a 550 motor is the length of the motor’s cylindrical case, or “can.” Both motors are the same diameter, but a 550 motor is about a centimeter longer than a 540.

What does t mean in RC motors?

The “T” stands for turns. This is the number of times the wire inside the motor is wrapped around the stator. A smaller number of turns typically equals less resistance, and more power. A higher number typically means more resistance, and less power.

How big ESC do I need?

If you are using 30amps ESCs, you should choose motors that are bigger than 2205 or faster than 2300kv, and propellers should be bigger than 5 inches. For examples 30 amps is required for the 2204 2700kv, 2204 3200kv, 2205 2700kv or 2206 1900kv(with 6 inch propellers).

What ESC do I need for 4S?

What size ESC should i use on a 4s setup? The ESC should be a match to the motor , and both should be rated to handle 4S . I find the max amps the motor can handle and get esc over that by 20 amps. I would at least consider a switch-mode ESC or consider an external BEC.

How many turns is a 3300kV motor?

3300kV is closer to 13.5 in most situations, apples for apples. Another big diff in motor kv ratings – some test motor kv unloaded and some test with the motors loaded and not all of them will tell you which method you’re looking at.

How many turns is a Velineon 3500?

The Velineon 3500 motor is a 10-turn, 3500 kV motor optimized for the best speed and efficiency in lightweight 1/10 scale models.

How many KV is a 13.5 motor?

That chart, a few posts up, is probably at the far end of maximum Kv rating scale. I have some 13.5T, and 17.5T motors that have some very different Kv “numbers” associated with them when compared to the chart, e.g., my mild 13.5T is said to be a 2550Kv motor, and one of my 17.5T motors is said to be 2250Kv.

Can you mix and match ESC and motor?

For the most part, yes, you can. A few things you have to consider…in most cases, you can’t run a sensored motor on a sensorless ESC for example. Mostly you have to make sure the ESC can handle the motor wind or KV.

Can any brushless motor work with any brushless ESC?

Any brushless esc will work with any brushless motor. Making sure you have a large enough esc is another thing. That ESC will work fine for that motor, as the motor is rated at 18A max and the ESC will handle up to 40A.

Is a higher amp ESC better?

A high amp esc will usually have better internals than a lower amp esc. Keep tthe questions coming, you do not learn without asking! Amp rating generally means you can run a more aggressive motor (mod motors) with higher amperage. For example, the Hobbywing Justock is just a 45a ESC.

Can you replace a brushed motor with a brushless one?

In order to change over from brushed to brushless, you must first purchase a new brushless motor. It is not possible to convert the motor itself from one type to the other. In addition, the brushless motors take a different type of electronic speed controller (ESC), so that must also be replaced.

Do I need a new ESC for a brushless motor?

Yes, you need a brushless ESC for a brushless motor. You need an esc that can handle the current that the motor pulls. Just the fact that it says its rated to 14 amps means that it will work up to 14 amps.

Does lower KV mean more torque?

Kv allows you to get a handle on the torque that can be expected from a particular motor. Torque is determined by the number of winds on the armature and the strength of the magnets. A low Kv motor has more winds of thinner wire—it will carry more volts at fewer amps, produce higher torque, and swing a bigger prop.

What does 12t mean on RC motors?

A 12 turn motor will be tons faster and will drain a battery faster . Just as he said. a twelve turn motor will have more RPM, less torque, and draw more current. The number or turns refers toi the number of times the wire is warpped around your armature in the motor.
