How do I choose the right motor for my RC car

Which motor is best for RC car?

The higher efficiency of brushless motors compared with brushed DC motors has two major implications for RC aircraft projects: Brushless motors use less electricity to output the same power as a comparably-sized brushed motor, meaning Makers get more power from the same battery.

How do I choose an RC motor?

Inrunners run better at higher RPM (2000-10000 RPM/V roughly) and outrunners run better at lower RPM (1000-2000 RPM/V roughly). Inrunners tend to be bigger for lower RPMs than outrunners. You can guess that the first thing you need to decide then is what speed (RPM) you want your motors to run at.

What size RC electric motor do I need?

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.

What is the fastest brushless RC motor?

“The Traxxas XO-1 is the fastest RC car, full stop. The largest brushless motor on offer propels the car from 1 to 60 in 2.5 seconds. Not only is this car stylish, but it also reaches speeds over 100 miles per hour.”

What type of motor is used in RC cars?

There are two different types of rc motors. Brushed and Brushless. Each motor type has its own kind of ESC (Electronic Speed Controller).

Is a higher kV motor better?

Generally speaking the more Kv a motor has, the more RPM and more power. … A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor. The turn rating is inversely proportional to the power generated by the motor.

What is a good RC car to start with?

The Traxxas XL5 RC car range is a famous line up with models such as the Traxxas Slash, Rustler, Stampede and Bandit which are all specifically designed for beginners and have helped thousands get into the hobby.

What is a 540 size motor?

Those numbers refer to the motor diameter. 540 has a diameter of 36mm. 380 has a diameter ~28mm. 280 has a diameter of 24mm. The S, L or XL after the numbers refers to the motor length.

Which electric motor is equal to what glow engine?

25 size engine equals about 500 watts, a . 60 size engine equals around 1200 watts and a . 90 size engine equals about 1800 watts of electrical power. When considering a 4-stroke glow engine, the conversion factor is around 1500 watts per cubic inch.

What do the numbers mean on RC electric motors?

Generally, the first two numbers indicate the diameter of the entire can of the motor OR the diameter of the stator (the inner part of the motor) only. … Similarly, the second pair of numbers can indicate either the height of the entire motor, or only the height of the stator.

How do I choose a BLDC motor?

The key to rating a BLDC motor is torque. This particular design is rated at 6.9 inch-pounds of torque and like all brushless DC motors, the maximum torque rating is independent of speed. The only limitation is that when the speed is lower than 300 rpm, cogging may occur with the motor.

How do you determine the RPM of a motor?

How to Calculate Motor RPM. To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.

Which motor is used in tramways?

The DC motor was the mainstay of electric traction drives on electric and diesel-electric locomotives, street-cars/trams and diesel electric drilling rigs for many years. It consists of two parts, a rotating armature and fixed field windings surrounding the rotating armature mounted around a shaft.
