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. 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.
Is it better to have a higher Kv or lower?
Generally speaking the more Kv a motor has, the more RPM and more power. A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor. The turn rating is inversely proportional to the power generated by the motor.
Do higher Kv motors use more battery?
Both motors are using the same amount of power to produce the same RPM. (Power(watts)=Current(I) x Voltage(V)). So the lower KV motor with the high voltage battery is using the same relative amount of power(watts) as the higher kv motor with the lower voltage battery.
What does Kv mean in voltage?
Definition of kilovolt : a unit of potential difference equal to 1000 volts.
What does 1000Kv motor mean?
Suppose if you are having a motor with 1000Kv rating it means that it will produce 1000 RPM when 1 volt is supplied. Suppose you are using a 3 cell battery which gives 12.6V.
How many turns is a 3300kv motor?
3300 is 13.5 equiv if it were a Novak motor.
What does 12T mean on RC Motors?
Twelve turns around each motor pole using triple wires. Three wires are would twelve times around the pole. A 12T double would use two wires wound twelve times and a 12T single a single thicker wire wound twelve times around each rotor pole.
How many amps does my motor draw?
Calculate the amps used by dividing the wattage by the voltage. For example a 500-watt motor — running on 50 volts — will draw 10 amps. A motor with the same wattage — running on 20 volts — will use 25 amps. This is the theoretical number of amps used by the motor.
How do I choose a Kv motor?
The KV value can be determined by the number of copper wire windings on the stator. Generally the higher number of winds decreases the KV of the motor, while lower number of winds increases the KV. The magnetic strength of the magnets can also affect the KV value, stronger magnets will increase KV.
What is the fastest brushless RC motor?
“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.”Oct 29, 2020.
How many volts is a police taser?
The electrical output of the TASER is 50,000 Volts. The voltage may seem high, but the amperage on both systems is well below safe limits.
Is kV higher than volts?
One kilovolt is equal to 1,000 volts, which are the potential difference that would move one ampere of current against one ohm of resistance. The kilovolt is a multiple of the volt, which is the SI derived unit for voltage.
How do you use kV?
To convert a volt measurement to a kilovolt measurement, divide the voltage by the conversion ratio. The voltage in kilovolts is equal to the volts divided by 1,000.
What does 2300kv mean?
See all questions about this product. Showing 1-4 of 4 answers. Brushless motors are rated in a few things, KV being one of them. KV Means RPM/Volt. For instance, if you have a brushless motor rated at 2300kv at 12 volts, the motors RPM will be 2300X12=27,600rpm in an unloaded state (no prop).
Why does a brushless motor have 3 wires?
there are 3 wires because it’s a 3 phase brushless system. at any given time two provide power and the other is a sensor. So even though they may split their time doing each, at a split second in time two provide power and the third is a sensor.
What is the rpm of brushless motor?
In practice, brush motors tend to be run below 10,000 RPM. A brushless motor of similar size and magnetic design can be operated at much higher speeds, reaching 100,000 RPM in some cases. These are perfect motors for applications where speed is critical.
How many turns is a castle 4600kv?
11 turn Technical Specs Input Voltage Range: 2-3S LiPo Kv: 4600 Max. RPM: 100,000 Size: Length: 49.5mm Diameter: 36mm.
What is the difference between a sensored and sensorless motor?
All brushless motors used in RC applications have three main wires, but sensored motors have an addition multi-wire loom that connects the “brains” of the speed control to the motor. Sensorless motors simply do not have sensors inside the motor—hence the name sensorless.
How do you make an electric motor spin faster?
The speed of rotation of the coil can be increased by: increasing the size of the current; using a stronger magnet; increasing the number of turns of wire in the coil; reducing friction between the coil and the axel it rotates on.
How can I make my brushed motor faster?
Sealed endbell motors need a lot of running to break in their hard compound brushes. Running it partially submerged in water helps break them in faster. Water dipping is a trick old-school guys used to break in their motors, but it would also help clean your brushed motors.
What is Kv rating on RC motors?
The Kv rating (not to be confused with kilo-volt) is the RPM of the motor (k) per volt (V) with no load. For example, a brushless motor with a Kv rating of 3000 powered by a 12V power source would be capable of 36,000 RPMs (multiply 3000×12). This is the max RPMs that this motor can reach under no load.
Is the Titan 12T motor waterproof?
