Electric Rc Plane Motor Guide

But the 11x5 prop will cause the motor to draw more current.

Electric rc plane motor guide.

We break the numbers out as follows. 1 10 4 pole esc brushless motor combo 3000kv. The larger the propeller s diameter and pitch the more current the rc electric motor will draw for a given rpm. The kv rating gives you the no load rpm that you can expect per volt of current.

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. The motor above runs at 1400 kv. This is why you need a speed controller to convert the battery s dc power into ac. The standard motor that you put in your rc plane is brushless which means it runs off of ac current.

For example the 200kv motor will run at 2400 rpm s regardless of whether it has a 10x6 prop or a 11x5 prop. For example when powered by an 11 1 volt battery a motor with a kv rating of 860 will produce a no load rpm of 9546. Any load on the motor such as a prop will reduce this number. Let s assume we have a 5055 3000kv brushless outrunner motor.

Electric motor power is stated in watts. 750 watts 1 horsepower. Drawing too much current will destroy the motor. 3 5mm bullet ec3 74 99 price reduced from 84 99 to 3 6 out of 5 customer rating.

The chart below also lists the roughly comparable glow and gasoline power systems for reference. Park 480 brushless outrunner motor 910kv. 50 55 3000 50 the first two numbers represent the diameter of the motor s housing in millimeters. When choosing a motor there are two basic things you need to look for.

At rc planet you ll find the largest selection of aircraft motors. Brushless motors use a standard numbering scheme to describe their physical size and kv rating. From the electrifly ferrite motors and c28 30 brushless motors to the rimfire outrunner brushless motors ammo brushless inrunner motors and more all at a guaranteed low price.
