Electric Rc Plane Motor Guide

Park 480 brushless outrunner motor 910kv.

Electric rc plane motor guide.

Drawing too much current will destroy the motor. 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. Let s assume we have a 5055 3000kv brushless outrunner motor. 750 watts 1 horsepower.

When choosing a motor there are two basic things you need to look for. The chart below also lists the roughly comparable glow and gasoline power systems for reference. For example the 200kv motor will run at 2400 rpm s regardless of whether it has a 10x6 prop or a 11x5 prop. 1 10 4 pole esc brushless motor combo 3000kv.

The standard motor that you put in your rc plane is brushless which means it runs off of ac current. 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. 3 5mm bullet 49 99 price reduced from 63 99 to 4 1 out of 5 customer rating.

At rc planet you ll find the largest selection of aircraft motors. The kv rating gives you the no load rpm that you can expect per volt of current. This is why you need a speed controller to convert the battery s dc power into ac. The motor above runs at 1400 kv.

50 55 3000 50 the first two numbers represent the diameter of the motor s housing in millimeters. 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. Any load on the motor such as a prop will reduce this number. In this example 50mm 55 the second two numbers represent the length of the.

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. Electric motor power is stated in watts.
