What is the difference between inrunner and outrunner motors?
With conventional motors, the magnets are attached to a shaft that rotates on the inside of the stator coils. This is called an inrunner motor. With an outrunner motor the magnets are attached to a ring or sleeve on the outside of the stator coils.
What is an inrunner electric motor?
The term inrunner refers to an electric motor where the rotor (runner) is inside the stator. The term is in particular used for brushless motors to differentiate them from outrunners that have their rotor outside the stator. The vast majority of electric motors are inrunners.
How do I choose a brushless RC motor?
To compare speeds, you’re going to want to look for a KV number. KV = revolutions per volt. For every volt that’s fed to the motor, in a no-load condition, the number is how many times the motor would turn. This also means that increasing the voltage will make the motor spin quicker.
What’s the difference between brushed and brushless RC motors?
Whilst in a brushed motor there is typically a red positive and a black negative wire connected (as seen in the photo above), brushless motors rely on the ESC to switch up the power signals sent down these three wires.
What does the T mean on RC car motor?
The “T” stands for turns. This is the number of times the wire inside the motor is wrapped around the stator. A smaller number of turns typically equals less resistance, and more power. A higher number typically means more resistance, and less power.
Do Brushless RC motors wear out?
If you are looking for a motor with a long life expectancy, consider a brushless motor. Brushed motor life is limited by the brush type and can attain 1,000 to 3,000 hours on average, while brushless motors can attain tens of thousands of hours on average, as there are no brushes to wear.
How do I choose a KV RC motor?
If a kv rating is used, then you need to choose a motor with a lower kv value than the limit. Other ESC related factors to take into consideration include the size of the ESC, making sure it fits properly into your car.
How long can a brushless motor run continuously?
Operating Life: If you are looking for a motor with a long life expectancy, consider a brushless motor. Brushed motor life is limited by the brush type and can attain 1,000 to 3,000 hours on average, while brushless motors can attain tens of thousands of hours on average, as there are no brushes to wear.
