Electric Rc Plane Motor Guide

Let s assume we have a 5055 3000kv brushless outrunner motor.

Electric rc plane motor guide.

We break the numbers out as follows. 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. Brushless motors use a standard numbering scheme to describe their physical size and kv rating.

3 5mm bullet 49 99 price reduced from 63 99 to 4 1 out of 5 customer rating. Electric motor power is stated in watts. 750 watts 1 horsepower. 50 55 3000 50 the first two numbers represent the diameter of the motor s housing in millimeters.

Park 480 brushless outrunner motor 910kv. 1 10 4 pole esc brushless motor combo 3000kv. At rc planet you ll find the largest selection of aircraft motors. When choosing a motor there are two basic things you need to look for.

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. For example the 200kv motor will run at 2400 rpm s regardless of whether it has a 10x6 prop or a 11x5 prop. The standard motor that you put in your rc plane is brushless which means it runs off of ac current. 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.

In this example 50mm 55 the second two numbers represent the length of the. Any load on the motor such as a prop will reduce this number. 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. But the 11x5 prop will cause the motor to draw more current.

This is why you need a speed controller to convert the battery s dc power into ac. Drawing too much current will destroy the motor. The motor above runs at 1400 kv.
