Which motor is used in RC helicopter?

An RC helicopter is a type of remote-controlled aircraft that is powered by an electric motor. The motor used in an RC helicopter is typically a brushless DC motor, which is a type of electric motor that uses permanent magnets to generate torque. Brushless DC motors have several advantages over traditional brushed DC motors, including higher efficiency, higher power density, and greater reliability.
Brushless DC motors are typically used in RC helicopters because they are more efficient and reliable than brushed DC motors. Brushless DC motors are also more powerful than brushed DC motors, which allows them to generate more torque and lift more weight. This makes them ideal for powering RC helicopters, which often require a lot of power to stay in the air.
Brushless DC motors also have a longer lifespan than traditional brushed DC motors, which is important for RC helicopters. The motor is the most expensive and important part of an RC helicopter, and having a motor that lasts longer can save money in the long run. Brushless DC motors also require less maintenance than brushed DC motors, which is another benefit.
When it comes to choosing a brushless DC motor for an RC helicopter, there are several factors to consider. The size of the motor is important, as it needs to be able to generate enough torque and power to keep the helicopter in the air. The KV rating of the motor is also important, as it determines how quickly the motor can spin. Higher KV ratings mean faster motor speeds, which is important for RC helicopters.
The type of ESC (electronic speed controller) used with the motor is also important. ESCs control the speed and direction of the motor, and they need to be compatible with the motor in order to work properly. The ESC also needs to be able to handle the current draw of the motor, as too much current can cause the motor to overheat and fail.
In conclusion, the motor used in an RC helicopter is typically a brushless DC motor. Brushless DC motors are more efficient and reliable than brushed DC motors, and they are also more powerful. When choosing a brushless DC motor for an RC helicopter, it is important to consider the size, KV rating, and type of ESC that is used with the motor.
