Is a higher Kv brushless motor better?
Quick answer: no, higher Kv is not better. It’s not worse either. It’s a key property of the motor that you need to look at to get a motor that fits your system (batteries, ESC, car).
What is the difference in Kv on brushless motors?
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.
What do Kv ratings mean on brushless motors?
The Kv rating of a brushless motor is the ratio of the motor’s unloaded rpm to the peak voltage on the wires connected to the coils. Knowing the Kv rating of a motor will help you determine how fast that motor will rotate when a given voltage is applied to it.
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.
Is lower Kv more efficient?
Usually high voltage, low amp setups are more efficient than high amp systems. Ymmv. Lower KV motors have more Kt and are more efficient.
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 turns is a 3800kv motor?
1 turn. Location: RIP ‘Chopper’, 4/18/13 miss you bud:( Why do you want to know? Kv rated motors don’t relate to motors rated in turns.
How do I know what size brushless motor I need?
Electric motor power is stated in watts. 750 watts = 1 horsepower. An easy way to estimate power needs for RC hobby applications is to use 100 watts per pound for sport flying, 150 for aggressive aerobatics, 200 watts per pound for 3D flying.
Do lower Kv brushless motors have more torque?
Lower Kv motors do have a higher torque constant. However, by nature they are not able to sustain the same amount of current output as a higher Kv motor.
How many Kv is a 8.5 turn motor?
A 5000 KV motor is a 5000 KV motor. A Novak 8.5 “turn” is rated at 5000 KV but another manufactures 8.5 may be different as most do not post their KV rating.
How many Kv is the Traxxas Velineon motor?
3500 kV
The Velineon 3500 motor is a 10-turn, 3500 kV motor optimized for the best speed and efficiency in lightweight 1/10 scale models.
What is motor KV rating?
The Kv rating designates the RPM a motor will spin at full throttle when unloaded given an input voltage. To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt.
What Kv motor is best for crawling?
20t CrawlMaster, or 2200kv brushless for slow going and long run times or a 27t TorqueMaster, 13t CrawlMaster, or 3300/3500kv brushless for more power and wheel speed. Don’t let your motor temperature get over 160°F (70°C) for best motor life!
What Kv is a 10.5 t?
Novak’s 10.5s are 4,200KV.
How many KV is the VXL?
3500 KV
Traxxas Velineon Vxl-3s 3500 KV Brushless Motor 3351r 4 Pole Slash Rustler.
What do outrunner motor numbers mean?
Magnet Configuration 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. Most out-runner brushless motors follow the 12N14P configuration.
What size is Velineon 3500 brushless motor?
Can Diameter: 1.42″ (36mm) Can Length: 2.22″ (56.3mm) Total Length Including Shaft: 3.02″ (77mm)
What does kV mean on a brushless RC motor?
Understanding Brushless RC Motor Specifications. 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. A motor with a higher kV will have more top end speed, but not as much acceleration/torque.
What is the Kv rating of a motor?
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…
How are RTR brushless motors rated?
Most of these RTR brushless systems are rated on a kV (or KiloVolt) system. Basically, the higher the kV, the more powerful the motor will be. However, that’s not the only way a brushless motor is rated. There’s yet another system in place that ranks how powerful a motor is – Motor Turns.
What is the max rpm of a brushless motor?
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.
