An electric motor is an electric machine that converts electricity into mechanical energy. The majority of electric motors operate through the conversation between the motor’s magnetic field and electric current in a wire winding to create force in the form of rotation of a shaft. Electric motors could be powered by direct current (DC) sources, such as for example from batteries, automobiles or rectifiers, or by alternating electric current (AC) sources, like a power grid, inverters or electric generators. A power generator is mechanically identical to an electric electric motor, but operates in the reverse direction, converting mechanical energy into electrical energy.
Electric motors may be classified by considerations such as for example power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors could be brushed or brushless, may be of various phase (see single-phase, two-stage, or three-phase), and may be either air-cooled or liquid-cooled. General-purpose motors with standard dimensions and characteristics provide convenient mechanical power for commercial use. The largest electric powered motors are utilized for deliver propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electrical motors are located in industrial enthusiasts, blowers and pumps, machine tools, household appliances, power equipment and disk drives. Little motors may be within electric watches.

special electric motor for speed-reducing YE2
The three-phase asynchronous electric motor of the YE2 series is in line with the third efficiency standard in the provisions of GB 18813-2012 “the energy efficiency limit and the energy efficiency rating of small and medium-sized three-phase asynchronous motors’. And the improvement of the efficiency in its style is based on the state’s requirements on the energy saving and consumption reducing of the manufacturing sector.
YE2 series motors with the mounting dimension relative to standard IEC60034, It has good features like the best structure, attractive appearance, low noise, high efficiency, high protection class and also high insulation class. YE2 series motors could be widely used in a variety of kinds of general use machineries like followers, pumps, machine tools, compressors, transportation and so on, and may also be found in the hazardous areas with oil and chemical, steel plants, mining industry.
◇ Site conditions
YE2 series motors air suitable for almost all applications and operate satisfactorily at temperatures from -20℃ to +40℃ and altitudes up to 1000 meters above sea level
◇ Temperature and Insulation
The Maters’ insulation system are designed by Class F(155℃), operated with Class B(80K). Which incerase the motor useful lifestyle and reliability.
◇ Cooling and ventilation
The typical cooling method is totally Enclosed Lover Cooled (TEFC) it accordance with IC411 of IEC60034-6. Regular motors include radialflow plastic fans
