The problems a DC motor may present

We must highlight the importance of a DC motor, the more we cannot but mention that they also have their problems, first because there is nothing determine what the correct and clear sense of rotation at the time of his departure, however the motor can either have its beginning to the left or the right.

Another downside is that many times the brushes can have start touching both plates and eventually there is no advantage in this sense being that with this engine does not departure, and that his departure is a total trust and a sense it is necessary that the brush is always send a quantity x of current to the rotor, provided this does not occur in any circuit between the plates and the brush.

In most dc motors it is possible on redressing this requirement provided that this is done correctly with the coil and the switch plate.

Aprenda o que comer antes de depois de treinar

Saber o que comer para ganhar massa muscular e emagrecer é muito importante, pois ingerir os alimentos corretos antes do treino ajuda o corpo a ter energia necessária para o treino e comer os alimentos corretos após o treino auxiliam no ganho de massa muscular.

Antes do treino é indicado ingerir um carboidrato de absorção rápida, como por exemplo, um copo de suco de fruta natural sem açúcar. Os carboidratos de rápida absorção proporcionam ao corpo a energia necessária para que, durante o treino, a gordura seja queimada e haja o ganho de massa muscular. Treinar de estômago vazio pode causar perda de massa muscular.

Durante o treino, é importante manter o corpo hidratado, portanto beba muita água. Os líquidos são importantes durante o treino pois contém sais minerais, que ajudam a controlar as reações químicas do corpo durante o exercício.

Após o treino, o corpo necessita da ingestão de alimentos ricos em proteínas principalmente de origem animal, como iogurte, carnes, clara de ovo, proteína do soro do leite, etc. Saiba mais sobre o que comer para ganhar massa.

Two main types of motor

The electric motor may have two basic types of power supply, AC or DC, can have two types of functioning as a synchronous motor or induction motor.

The synchronous motor is functioning at a constant speed; and uses an armature that has a constant electromagnetic field that should be already pre-defined, it will increase the response to the process of drag created by a rotating field. This engine is generally used when it needs stable speeds on the action of variable loads, and this synchronous motor can also be used where high power and energy that needs a constant torque. what you look for is lp-cc-1

Induction motor generally runs with a stable speed, which varies slightly with mechanical load that is applied to the shaft by its great simplicity, robustness, and low cost, this type of engine ends up being the most widely used of all is easily suited to almost all types of powered machines found in the market, the cost of maintaining this engine is also low and the service is easily found.
