The Operation of Engines

The electric motor is essentially a machine that aims to convert electric energy into mechanical and the operation of these electric motors is based entirely on the principles of electromagnetism, since the conductors located in a magnetic field and crossed by an electric current will undergo the action of a mechanical force, called torque.

The electric motor is proven to be the most applied of all other types found, since it can be transported in a simple way, be economical, be easy to clean, easy to operate, and easy to build and adapt to different loads.

Nowadays, the machines do not produce energy, that is, they convert other types of energy, into mechanical energy, thus guaranteeing its operation. Taking into account the great precision of the ozone layer’s preservation of the emission of pollutant gases, the electric motors need to be used in automotive vehicles, in order to save energy.

Some pollutant gases, such as carbon dioxide, that emanate from exhaust fumes from industries and automotive vehicles, have a dangerous capacity for damage to the ozone layer.

Solid Outboard Motors

Solid outboard electric motors do not have a squirrel cage in the rotor. The polar shoes at the time of departure have the behavior similar to that of a cage. The configuration of the pole shoes of this type of motor can be configured during its design, in order to adjust starting current and starting torque of the motor, adjusting to the load to be driven, the method and the starting conditions required by the application of the motor .

Because of the causes that are manifested in the polar shoes during the start and the very principle of getting the starting torque, we achieve high levels of torque in the match with low current levels. The effect of the eddy current formed by the rotating field on the surface of the pole shoes at the time of departure generates high currents in these regions.      VUHM3542-5

These currents produce high electromagnetic fields that relate to the rotating field produced by the stator, resulting in the starting torque of the machine. The transient high eddy current in the pole shoes causes high temperatures in this region, which in the design of the machine should also be analyzed, in relation to the insulation materials, material of the shoes themselves and fixing the field windings and also the cooling mode two poles.
