Grandiose rc cars motors evolution

Most rc cars motors have evolved. After the first bushes and motor system, manufacturers soon created a servo motor that replaced the relay that made the connection. Subsequently, the lower prices of electronic components and improved radio equipment, making the motor is regulated by trains of pulses of variable width, as opposed to a voltage variation, get the speed variation without unduly reducing engine torque delivered. But despite all these advances and improvements, are still less efficient than the engines, which are brushless. Look for the best rc cars models to ensure the best performance. You must search and select from the wide variety of engines, too.

Brushless motors have a particular relevance to the rc cars engines- they are the new phase or "brushless" (without brushes) with high performance and low power consumption. These engines are built in two ways:

1.       Inrunner or inner rotor, were first applied to model aircraft, in them, the wound is on the outer casing, while the rotor is in the interior, are the with smaller diameter and less torque but higher speed, its main use currently is in the turbines EDF and propeller propulsion gear reducers, especially planetary.

2.      Outrunner or rotating body. These are modeled on motors that are used in computing, in which permanent magnets are arranged in a ring around a group of coils arranged radially. These rc cars engines are larger in diameter, the pair is much higher, and work to schemes that allow the direct use of propellers, even with fairly large diameters relative to the total weight to apply to any specialty model aircraft.

To dispense the power of these electric motors, it is important to use specific drives, which generate a three-phase current which varies in frequency. These rc cars are powered by batteries that should be independent to power other electrical devices inside of the aircraft such as receiver and servos, although almost all general purpose drives have a power supply from batteries motor, and is responsible for, the lower the battery voltage when discharged, cutting engine power to maintain the radio equipment.

Depending on the nature of the batteries, the system of regulation changes to avoid damage, and a regulator for Ni-Cd or Ni-Mh short with voltages lower than the latter LiPo, its low weight and high charge density, are the most commonly used, however, there is a especially developed rc cars model that is required for intense shock and short nickel batteries still have a scope.
