electromechanical generator for converting mechanical vibrational energy into electrical energy are disclosed, electromechanical generator is elastically connected to the body by a biasing device, having a osci
More materials are piezoelectric than you might think. DNA, bone, and silk, all have this ability to turn mechanical energy into electrical. Scientists have created a variety of synthetic piezoelectric materials and found applications for...
Controlling electric motor speed is as “simple” as controlling the amount of electrical power delivered to the motor. In the following article, we are going to assume that we are looking at a steady state condition where there is no acceleration. To be more precise, for a given mechanical...
In this way, the rotor transfers its mechanical, rotational energy to the shaft, which enters an electrical generator on the other end. Generator - At its most basic, a generator is a pretty simple device. It uses the properties of electromagnetic induction to produce electrical voltage - a...
In an electric car,batteries produce electrical energy that is carried through a circuit(电路)) to an electric motor. The electric motor changes electricity from the batteries into mechanical energy, the energy of movement. This is what causes the wheels of the car to turn.When a person is ...
Just keep in mind that they all work on the same basic principle of converting mechanical energy -- spinning turbine -- into electrical energy. Of course, using a generator to make electricity is just the beginning. After you get your electrons moving along, you'll need an electrical circuit...
A speaker usually uses one rapidly moving diaphragm to make sound. The LRAD uses an array of piezoelectric transducers. A transducer is simply a device that changes one kind of energy into another kind of energy. In this case, it changes electrical impulses into sound. A piezoelectric material...
As we've already discussed, a generator converts mechanical energy into electricity. A motor works on the same principles, but in the opposite direction -- it converts electrical energy into mechanical energy. To do this, a motor needs a special kind of magnet known as an electromagnet. In...
What You Can Do With a Mechanical Engineering Degree. A bachelor's degree in electrical engineering is the standard entry-level credential within this field, though a master's orPh.D. degreein this area can improve a job candidate's marketability and allow that person to obt...
