If you're going for speed runs, higher kv is better. Only to a point. IMHO, a lower kv motor is better suited for speed runs because you can run more power through it, which, in the end, will result in higher speeds.
Also know, does higher kV mean more power?
Two motors, same can size, with the same gearing, the higher KV motor will run hotter, because it pulls more amps. It will also be making more power, moving the car (or quad or whatever) faster.
Also, what does a higher kV mean? Answer: “Kv” refers to the constant velocity of a motor (not to be confused with “kV,” the abbreviation for kilovolt). A high Kv motor has fewer winds of thicker wire that carry more amps at fewer volts and spin a smaller prop at high revolutions.
Likewise, does higher kV mean faster?
The kV rating (not to be confused with kilo-volt) is the RPM of the motor (k) per volt (V) with no load. A motor with a higher kV will have more top end speed, but not as much acceleration/torque. A motor with a lower kV will not be as fast, but will accelerate faster and have more torque.
Does lower kV mean more torque?
In summary, a low KV motor has more winds of thinner wire - it will carry more volts at less amps, produce higher torque and swing a bigger prop. So yeah, lower kv motors have thinner wires. Thinner wires mean more resistance and less current for the same voltage.

Do brushless motors have more torque?
Without having to worry about burning up brushes, a brushless motor can handle more current - and since current creates torque that means a brushless motor can produce higher torque without having its lifespan reduced. Thus a brushless motor can be more powerful than a brushed motor of the same size.What is T in brushless motor?
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.What is a kilo volt?
Definition of kilovolt. : a unit of potential difference equal to 1000 volts.What do the numbers mean on brushless motors?
The configuration number tells you how many electromagnets there are on the stator, and the number of permanent magnets there are on the rotor. The number before the letter N shows the number of electromagnets there are in the stator. The number before the P shows how many permanent magnets there are in the rotor.What is a 540 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. 540 motors are usually used in lightweight 1/10-scale vehicles, like touring cars, 2WD buggies, and stadium trucks.What does brushless mean?
A drill with a brushless motor adjusts its speed, torque, and power supply to match the task at hand. It'll sense if you're driving screws into a light material like drywall or a dense material like mahogany, and use only enough power to accomplish the job.What does 3000kV mean?
The 3000kV motor is moving air at very high speeds. If you put the same large propeller on it as you use on the 1200kV motor, you'll burn it up; it will be trying to move too much air, too quickly. (The load will be around 2.5 times as high at 3000kV as at 1200kV with the same prop.)What does 12 turn motor mean?
RE: Motors - (12 Turn Verses 20 Turn) 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.What does torque mean?
Torque is the amount of “turning power” you have, in the same way that you turn a wrench. 369 foot-pounds means that if you had a wrench that was 1 foot long, and applied a force of 369 pounds directly perpendicular to that wrench, you would get 369 foot-pounds of torque.How can I make my RC truck faster?

What does kV mean in voltage?
A kilovolt (kV) is a decimal multiple of the SI derived unit for electromotive force, electric potential (voltage), and electric potential difference. 1 kV = 1000 V. By definition, one volt is the difference in electric potential across a wire when an electric current of one ampere dissipates one watt of power.What does turns mean on a RC motor?
Turns. Turns refers to the number of times the copper wire has actually been revolved around the armature. The higher the number of turns greater is the torque generated and hence greater is the power delivered. However that also means less RPM rating for your rc car electric motor.What is the best Brushless ESC motor combo?

How do you calculate kv?
The formula to calculate Kv for a brushed DC motor is to just divide the speed by the generated DC voltage that you measure using your multimeter. Another option for brushless motors is to buy a BL motor tester that will calculate Kv for you.What does KV mean in texting?

How do I know what size my RC motor is?
The maximum current and power is what determines how large of a prop and what size plane can be used with the motor. Simply multiply the current by the battery voltage to get power. The larger the propeller's diameter and pitch, the more current the RC electric motor will draw for a given RPM.Which kV motor for drone?
KV. It's an important parameter of brushless motors, which indicates the theoretical increase of RPM (rotation per minute) when voltage goes up (without load, i.e. propeller). For example, when powering a 2300KV motor with a 3S LiPo battery (12.6V), it will spin at around 28980 RPM without props on (2300 x 12.6).How do brushless motors work?
A brushed DC motor has permanent magnets on the outside of its structure, with a spinning armature on the inside. In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator. A computer then charges the electromagnets in the stator to rotate the rotor a full 360-degrees.How do you calculate the RPM of an electric motor?
RPM = (120 * Frequency) / # of poles in the motor.By formula:
- ((Synchronous Speed – Rated Full Load Speed) / (Synchronous Speed)) * 100% = Slip Rating.
- ((1800RPM-1750RPM) / 1800RPM) * 100%= (50RPM/ 1800RPM) * 100%
- (50RPM/ 1800RPM) * 100%= . 027 * 100%
- . 027 * 100% = 2.7%
- Slip Rating = 2.7%
