Rc brushless motor kv explained

Similar to the LIPO overview from a while back here is a short video to cover the basics of brushless motor. Even though brushless motors are a type of AC motor, the assumptions made allow us to use Kv. Ok, lets start with kV ratings.

Things like the kV rating , battery voltage, how heavy the RC vehicle is, and gear ratio or prop size. Is this the speed that the motor runs at without a load ?

The most efficient speed ? Сохраненная копия Похожие Перевести эту страницу авг. Dumber question: How does your run-o-the-mill brushless ESC know . Does not mean KiloVolts as in electrical terms. T 3brushless motor kv difference.

No one standard exists for measuring the speed of the brushless motor.

Some manufacturers measure the speed by turns. Other manufacturers use a KV rating. Answer: “ Kv ” refers to the constant velocity of a motor (not to be confused with “ kV ,” the abbreviation for kilovolt). 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.

Volt Its how motors are rated. Lower KV = more torque ? Другие результаты с сайта forums. This is where the KV rating comes in (not to be confused with kV , which stands for kilovolts). Most outrunner brushless motors follow the 12N14P configuration. There are some specialist low KV multirotor motors which have a higher number of electromagnets and permanent magnets which allow the motor to create more torque more efficiently, however due to the added number of magnets these . Kv actually refers to the RPM of the motor per volt “without a load”.

This number will obviously be less once you have the motor inside your RC vehicle but this is . In recent days I have come into the situation where I need a new brushless system for my Traxxas Slash RaceSpec. It had a Castle Creations Mamba Max 7Kv system.

I know that this can be a devastating blow for any racer. Normal RC ESCs cannot do constant torque control or torque limiting, since they lack current sensing circuitry as a cost and weight saving measure. Most 2WD off-road RC cars and trucks are suited for a more standard 5size, two-pole brushless motor , and a handful of fourpole sensorless setups as well. Motor Types Explained. Today we are going to explain some basic information about Turns and Kv rating.

What does Kv tell us? Well, it is related to the power out from a motor. Brushless motors – how they work and what the numbers mean. When you want to buy a new brushless motor for your RC car, have you ever been confused why the motors are interpreted by Turns (T) or by Kv rating ?
