Rc Brushless Cars
RC brushless cars are those electric radio controlled cars that run on electric motors without moving parts. While a seemingly simple change to the regular electric motor is what a brushless motor is all about, the change it actually brings about to RC brushless cars is almost incredible. With greater performance and reliability in the picture, RC brushless cars are the best way to make your RC electric cars turn over a new leaf.
There are many ways to make things better in the world of RC electric cars and one of the most important and interesting ways is to turn those life-guzzling electric motors into the brushless motors. To understand exactly how a simple technological change to the motor can be, you need to understand the way the electric motor works.
In a regular RC electric car, the motor contains an armature coil that rotates in the middle of the two poles of an electro-magnet. The armature coil basically spins through 180 degrees, and to make it take a complete turn of 360 degrees, the poles of the electro-magnet need to be reversed. The brushes, in the motor, are responsible for changing this polarity and despite their effectiveness, there are several flaws in this design.
The speed of the brushes limits the speed of the motor and since they can only turn at a limited pace, there is always an upper limit to the motor. The electromagnet rests in the centre of the motor and that means that the motor will take a longer time to cool down. The number of poles on the armature is also limited by the use of brushes.
However, the biggest problem remains the reliance on these brushes which tend to wear out really quickly. This, accompanied by their tendency to make/break connections with sparking noises is a common factor with motors that contain brushes. With cheaper computers and technology coming into the play, the motor has been turned inside-out, making the entire motor more stable and long lasting.
In RC brushless cars, the motor has a static magnet, which has the armature coil rotating around it. There are computers that control the RC brushless cars' motors and that means that your motor runs more efficiently. There is absolutely no sparking or electrical noise while the brushes don't wear out at all because there aren't any to wear out.
The electromagnets rotate around the coil and that means that it is easier to cool while a lot more electromagnets can be placed to make the control more precise.
Thus, RC brushless cars have been a magnificent addition to the world of RC models and in terms of technology and general advances in the field of radio controlled electric models, there are few things better than RC brushless cars.
