BRUSHLESS MOTORS. what makes em so good? how do they work? why are they so expensive? gimme some details. thanks.
Brushless technology will be the future of RC Cars. What makes brushless so attractive is the ability of the motor to keep accelerating, the downside to that is it puts a large drain on the batteries. The windings are inside the can with the magnets wound on an arm rotating within the windings, but not touching them. As power is applied to the winding, the magnetic field is generated causing the magnets to rotate. More power applied to the motor, the faster the rotation. Because of no brushes, the can is cooler than regular brushed motors, and also more efficient. The most expensive part is the speed controller that controls the power and monitors the amp draw. Pretty soon we all will go this route as the posibilities of not purchasing brushes and replacement arms is becoming realistic, and cost effective.
