How do I choose the right motor for my RC car?

What motor should I use in my RC car?

What’s perhaps still the most common motor size used in RC cars, is often called “540”. These are used in many lighter 1/10 cars, while larger “550” or “1/8” sized motors are often used in heavier 1/10 vehicles and 1/8 scale cars. Brushless motors in this size are today often “4-pole” motors.

How do I know what size brushless motor I need?

The physical size of a particular brushless motor is usually indicated by a number that looks like this – ‘22-05′. The first number, 22, indicates how wide the motor is whilst the second number, 05, indicates the hight. Usually, these are written on the motor casing themselves to show you how wide and high they are.

What turn motor is best for RC drifting?

RC motors are measured in turns, which is the amount of winds in the electric motor’s coil, and the lower the number, the more powerful it is. A 9T motor for example, has a lot more power than a 17T motor. For drifting you ideally want a sensored brushless motor for the best throttle control, but other setups do exist.

How do you match a motor to an RC plane?

Simply multiply the current by the battery voltage to get power. The larger the propeller’s diameter and pitch, the more current the RC electric motor will draw for a given RPM. For example, the 200Kv motor will run at 2400 RPM’s regardless of whether it has a 10×6 prop or a 11×5 prop.

How do you determine the rpm of a brushless motor?

To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt. The more torque a motor needs to produce, the more current it will draw. The Kt rating designates the amount of torque a motor will produce given a current.

How do I know what size my RC motor is?

Electric motor power is stated in watts. 750 watts = 1 horsepower. 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.

How many turns is a 3300kv motor?

3300 is 13.5 equiv if it were a Novak motor.

Does lower KV mean more torque?

Kv allows you to get a handle on the torque that can be expected from a particular motor. Torque is determined by the number of winds on the armature and the strength of the magnets. A low Kv motor has more winds of thinner wire—it will carry more volts at fewer amps, produce higher torque, and swing a bigger prop.
