A complete burn out can result in an extensively heated working environment of alternator, so arrangements for keeping a controlled temperature should be put in place. In the rare case of fully burnt out stator coils, the solution is a complete replacement. The remedy to this effect is rewinding of short circuited group of coils in case of a partial damage. This causes a few or all of the coils to burn and your alternator stops working. The current produced tends to expand the copper wires, which, despite being very highly and sophisticatedly insulated, sometimes meets each other and gets short-circuited. The burning of any level in a stator happens due to short circuiting of very closely wound copper coils in the stator assembly. Actually, it is the stator which gets partially or completely burnt, while the latter being a rare accident. Despite its complicated structure, the stator mainly develops a single fault, which is commonly termed as a burned up alternator. The next and most complicated part of alternator is a stator assembly, which is wounded with carefully placed copper wires, very sophisticatedly insulated amongst each other and the rest of the body. Other than that, there is not much to malfunction in a rotor as it is, in effect, only an electromagnet. One of the important and most common cause is tightness of the belt, which can either be loose or tighter than desired. The rotor moves with the action of its bearings, which although have been made to wear in a long period of time, but certain factors can accelerate the wearing down process. Hence, the parts responsible for the rotary action are subjected to frequent wear and tear. The alternator works on the mechanism of rotation of rotor assembly. This device prevents overflow of the current and at the same time fulfills the deficiency of current supply to the system, as and when it occurs. For this purpose, an automatic voltage regulator device is attached to the system. Upon production of electricity, its output or the supply to different devices needs to be controlled. This induced current therefore produces electricity for the operation of all other devices attached. The turns of rotor creates a rotating magnetic field which results in the induction of alternating current in the stator. Classically speaking, a rotating magnet known as rotor is made to turn within a conducting material, which is wounded by coils in an iron core, and is called stator. The principle is the induction of alternating current in the conductor, when the magnetic field around it changes. The principle of generation of electricity by the alternators is similar to that of a DC generator. They have further subparts in them, details of which can conveniently be found in technical manuals or on internet. An alternator consists of essentially four parts the diodes, rotor assembly, stator and voltage regulator. Let’s have some understanding of what this alternator is all about and how it works. The alternators installed in power stations are of a huge size and capacity and are turbine driven. When a permanent magnet is used for electricity generation, the alternator is called magneto. There are certain types of alternators based on the method of electricity production. Then, the electricity that is formed provides the necessary voltage that helps run the electrical systems and components that are found in forklift trucks. The alternator creates AC power using electromagnetism that is developed through the interaction of the rotor and stator. Alternators generate power for the other electrical components of the forklifts, including the instrument panel. Forklift alternators form essential part of their charging systems. The charging system of a vehicle consists of a battery, the voltage regulator and an alternator.
