Electric motor and Generator

Most electric motors operate through the interaction between the magnetic field of an electric motor and winding currents to generate force. In some applications, such as in the transport industry, in the Renaissance braking with traction motors, the electric motor can be used in contrast to the generator as well as to convert mechanical energy into electrical power.

AC and DC motor usage

Found in various applications such as industrial fans, blowers and pumps, machine tools, home appliances, power tools, and disc drives, electric motor can be operated directly from sources (DC) sources, such as batteries, automobiles or rectifiers, or by , Or from alternate current (AC) sources, such as power grid, inverter or generator. Small motors can be found in electric clocks. The general purpose motor with high standardized dimensions and characteristics provide convenient mechanical strength for industrial use. The largest ship of an electric motor is used with 10 and more MW rating for propulsion, pipeline compression and pumping storage applications. The electric motor can be classified by electric power source type, internal construction, application, type of seed production, etc.

Electric motors are used for the production of linear or rotary force (torque) and should be separated from instruments like magnetic solenoids and loudspeakers that convert electricity into motion but do not produce usable mechanical strengths, which Respectively known as actuator and transducer.

When the flow flows through an operating wire, and an external magnetic field in that flow is applied, the operating wire experiences vertical forces in the direction of that region and current flow. The left hand shown in the depiction can be arranged so that the three interconnected orthogonal axes can be represented on the thumb, precursor and middle finger. Each finger is then assigned to the amount (mechanical force, magnetic field, an electric current). Right, and left hands are used for generators and motors respectively.

The magnetic field of the electric motor and generator

If the external magnetic field is applied horizontally, then it crosses the flow of electrons (in the wire conductor, or in the electron beam), both the magnetic fields will interact. Michael Faraday presented a visual parallelism for the form of frictional magnetic lines of force: in the conductor, they make the circle centered around the conductor; Running in parallel lines in the exteriorly applied magnetic field. If people on one side of the conductor are walking in the opposite direction (from north to south magnetic pole) in the opposite direction of the conductor, they will be removed so that the conductor on the other side (because the magnetic lines of force cannot be used one another Opposite cross or race).

As a result, on that side of the conductor, there will be a large number of magnetic field lines in a small space, and they will be reduced on the original side of the conductor. The magnetic field lines of force are no longer straight lines but are winding to run around the electric conductor, they are tension (like an elastic band) with stress in energy in the magnetic field.

The energetic field is now mostly obsolete, its direction or elimination creates a force in the direction of Newton's Third Law Motion in one direction. A system is only a running object in this power (electric conductor). the net effect is a physical force which works to carry the electric conductor out of the applied magnetic field in the direction outside the magnetic flux (Motor) if the conductor is taking up conventional current. The external magnetic field is moving away from the viewer, then the physical force conductor He will work to push the left side. This is the reason for the torque in the electric motor. (Electric motor is constructed so that the removal of the conductor from the magnetic field can be placed in the next magnetic field. and this switching can be continued indefinitely.) This difference is between electric motor and generator.

Faraday's law

The induced electromotive force in a conductor is directly proportional to the rate of change of the magnetic flux in the conductor.
