Rc cars- Operation and high-performance drives

The Rc cars operation of the variable resistance 3 terminals is very simple it is to use a 3-terminal resistance between the battery and motor. As soon as you get your radio control cars you will become familiar with everything. For example, depending on this current flow terminal will cover more or less length of resistance as heat disperses more or less energy. This translates into a higher or lower voltage so the motor will spin faster or slower.

In this case we have 3 speeds, smaller speed corresponds to the passage of current through the entire length of the resistance and the highest speed corresponds to no current flows through the resistive element of it. For varying the current Rc cars flow further provides a circuit of tracks over which rotate in one direction or another by a pair of contact terminals that carry current to the motor.

 The twisting motion will give it the servo motor according to the orders given from the transmitter. While the station's stick in the neutral position one of the terminals will not contact any board leaving the engine off (in the case of a station sticks, in the case of a station with wheel and trigger without pressing the trigger). The reversal Rc cars is achieved by reversing the polarity so the motor rotates in the opposite direction. These drives have the disadvantage that they are not very progressive and significant note that the passage of a drive for speed rheostat.

 It consists of a variable resistor wound on a contact that slides driven by the servo motor. With the movement of the contact electric current passes do more or less length of resistance and having many turns the rheostat speed jumps are much smaller. With these Rc cars types of drives there is no retreat but instead have an electric brake. When we stop feeding the left engine with the battery and a resistor connected between the motor terminals so now the engine due to the inertia that has generated current is dissipated in this resistance and create a magnetic field to stop quickly.

These mechanical drives are much cheaper, hence, the Rc cars is lowered. They are ideal for beginners. In terms of maintaining contacts should be kept free of dust and prevent excessive friction to the drives to be protected from dust with a plastic cover you can use a special grease for electrical contacts which reduce friction and to prevent sparks what tracks will wear more slowly.
