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

special electric motor for speed-reducing YE2
The three-phase asynchronous engine of the YE2 series is based on 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 design is in line with 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 possible structure, attractive appearance, low noise, high efficiency, high protection class in addition to high insulation course. YE2 series motors could be widely used in various kinds of general use machineries like enthusiasts, pumps, machine equipment, compressors, transportation and so forth, and can also be found in the hazardous areas with essential oil and chemical, steel plant life, mining industry.
◇ Site conditions
YE2 series motors air suitable for virtually 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 were created 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 completely Enclosed Lover Cooled (TEFC) it accordance with IC411 of IEC60034-6. Standard motors are equipped with radialflow plastic fans
