a Solution to Reduce the Environmental Impact of electric vibrator

The electric vibrator is an electromechanical reversible energy converter, which in motor regime converts electrical energy absorbed at terminals into mechanical energy available to the rotor shaft and in generator regime it converts mechanical energy into electrical energy. Rarely, electrical machines can work in the brake regime in which both electricity and mechanical energy is transformed into heat.
Whatever the operation regime, the conversion process is always accompanied by irreversible transformation of the energy into heat.
Like many other industries, electrical machine building industry is a polluting one. It can be considered without any doubt that environmental pollution begins in the phase of exploitation of minerals from which metals are extracted from which components are manufactured (Al, Cu, Fe, etc.).Pollution continues throughout the life of the machine, through: development of heat, generation of external magnetic fields, noise, vibration, emissions of volatile substances in electrical materials, loss of lubricants in service. When the unity power of electric machines is larger, the values of these parameters are higher.
At the disposal of the electrical machines, the environmental impact consists in gas emanations, smoke, dust and other substances resulting from dismantling, in order to return the materials to the economic cycle.
As previously shown, electric machines transform a primary energy form into another form of usable energy; this transformation also generates a quantity of energy that’s either unusable directly or very difficult to recover – the heat. Schematically, this transformation at the electrical machine level can be represented as follows:
From the standpoint of the environmental protection process, in addition to the useful forms of energy (mechanical or electrical), the electrical machines also produce losses, as heat[4]. The lost energy can be recovered by taking the heat from the cooling circuit either directly or from the space immediately adjacent to the machine and using it in a different process than the electromechanical conversion process by which it was generated. If it’s not used, this heat can be regarded as a waste that adversely affects the environment.
In accordance with the above analysis, a direction to reduce environmental effects of electric machines is the minimization of the heat loss residue. It is obvious that environmental effects depend on the type of conversion used, on the construction and machine size. Therefore, a solution to mitigate the impact of the heat over the environment is to recover the heat and reuse it. However, this can be achieved only for large machines (either motors or generators).
For the new electrical machines, solutions need to be found from the project phase to: increase the power efficiency (by using new materials), insure easier dismantle, simplify the construction method.
For the machines that are already in production, the impact over the environment can be reduced by increasing their life through a rational maintenance plan and by finding overhauling solutions, which is requires less resources and less energy than the dismantling and replacement of the defective parts. Such a solution is described below, for a certain kind of motors, having a single demountable bearing shield.
