Electric RC Car Subsystems

In any complex system like an Electric RC Car, as it is, there bound to be many subsystems. The life and performance of an Electric RC Car as a whole depends on, among others, the life, performance and efficiency of the subsystems, besides the usage conditions and the driver's skills. More over, if you are a mechanical enthusiast who assembles an Electric RC Car oneself, you are bound to know the subsystems well.

Similarly, if you want to upgrade your existing Electric RC Car all by yourself, you also need the know-how of subsystems for correct upgrade decisions. Because, not often it is the motor power that when increased can give improved performance, to the extent you expect. May be, a faulty steering system reducing the traction, an improper connection to the battery failing to drain it well or even just the tyres need to be changed or you need to learn that swaying the car on to dirtier parts of track may attract dust, reducing the friction and affecting the performance.

In an Electric RC Car there are mainly the following subsystems:

Drive Motor System of an Electric RC Car consists of a motor, cooling arrangements in the form of a heat sink with a little fan, ESC and Battery tray.

Battery system consisting of a battery tray to receive a battery pack of four or six cells of Ni-Cd type or Ni-mH type or one or two Lithium cells etc., of suitable range of voltage and current.

Electronic Speed Control System offers more advantages than Servo based mechanical speed control system.

Micro Controller System consisting of a circuit board that interfaces the microprocessor/ microcontroller with the optical sensors, the speed control systems and the drive motor and other systems. It also performs any other smart functions an Electric RC Car is designed to do.

Radio Controller System using Frequency Modulation (FM) with at least two to three channels.

In addition to the above, there are Steering subsystem, Transmission subsystem, suspension systems, wheels and axles, internal electrical systems etc. as well. So, have an Electric RC Car, know its subsystems well, care for it and enjoy it for long!
