It varies with motor type. It will spin a 12x6 prop at 6900 rpm on 7 cells and draw only 27A producing 249W.

The continuous current rating of a motor is the Amps that a motor can handle safely over a long period of time.
Engine kv rating. Rating of a brushless motor is the ratio of the motors unloaded rotational speed measured in RPM to the peak not RMS voltage on the wires connected to the coils the back EMF. Brushless Motor Kv Rating. The motor Kv constant is the reciprocal of the back-emf constant.
The engine has to be able to turn the alternator of course but if we can assume thats true and it should be than the KW and KVA ratings will depend on the current rating of the alternator. Inrunner or outrunner number of poles number of turns winding resistance etc. Kv refers to the constant velocity of a motor not to be confused with kV the abbreviation for kilovolt.
Generally speaking the more Kv a motor has the more RPM and more power. Read on to learn more about Kv ratings. The definition of the Kv value is how many RPM a motor outputs per every volt.
I often get asked what motor size and KV should be used for FPV drones of certain prop size and LiPo voltage. Kv not to be confused with kV the abbreviation for kilovolt talks about the constant velocity of a motor. Is there more in this rating.
This motor has more torque and you might want to increase the voltage to take advantage of that characteristic but watch the amps because this motor has an amps limit of 52A for 60 seconds. This current is measured in Amps. This directly translates in to unloaded RPM for any specific application when the Battery Voltage is known.
What is the Kv rating of an electric motor. For example a 9000Kv motor would be faster than a 2200Kv motor. To estimate the RPM of a motor simply multiply the Kv value by the battery voltage.
So I made this list based on the builds I have flown and seen over the years. As we saw before the Kv rating is the relationship between input voltage and maximum RPM. Prop Size Motor Size KV LiPo Cell Count and Weight for DIY FPV Drones.
The higher the KV rating means higher top speed but lower torque. RPM Kv Voltage. A 2300 Kv motor will generate a 1 V back-emf when the motor is rotating at 2300 RPM.
When you have lower the KV rating means higher torque but lower top speed. Id say it depends as much on the alternator as it does on the engine HP. I know a higher Kv rating translates into more RPMvolt and a lower Kv into more torque at a lower RPMvolt.
However since through gearing two otherwise identical motors can be configured to have the same RPMvolt and ft-lbvolt it seems there must be more to consider when purchasing a brushless. If your street racing you would want to go with a higher KV While for off-road a lower KV will be better. If Kv is like horsepower then Turns is the physical attribute of.
There is no single answer but a range of options you can explore. It is measured by the number of revolutions per minute rpm that a motor turns when 1V one volt is applied with no load attached to that motor. Kv is in units of RPMVolt.
The KV rating means the motor has one or the other high torquelow rpm or low torquehigh rpm. It has a KV rating of 985 - much lower than the hotter 30256. So Kv tells us the relationship between motor speed and generated back-emf.
It is common practice to use Nominal voltage values for the unloaded RPM. Real-World Effects of Brushless Motor Kv Rating. Kv or RPMVolt is way of determining the use of a motor.
At 23000 RPM that motor will generate 10 V. For example an unloaded motor of 5700 rpmV supplied with 111 V will run at a nominal speed of. Motors are labeled with turns or a Kv rating--what does that mean.
Kv describes the RPM revolutions per minute a motor does per Volt that is put into it. This represents the average unloaded RPM throughout a full battery discharge. You can normally find the estimated current rating of a motor on the factory specs sheet.
The Kv rating designates the RPM a motor will spin at full throttle when unloaded given an input voltage. Therefore the Kv rating for a motor is an indication of the number of revolutions per minute RPM of the motor. The RC model brushless motors are often characterized by their Kv rating.
Motors are usually marked with dimensions and Kv together so a typical mark on the motor would look like 22062300. Another seldom-seen rating is Ke the reciprocal of Kv and adjusted for angular speed. The kv can be used to find the maxium voltage that can be applied to a certain motor.
Whether you are using brushed or brushless motors the principle of electromagnetism is at the root of your motors. The max current rating refers to the maximum amount of current that a motor is able to handle safely. The second number is referring to the Kv rating of the motor.
