YE4 series three-phase asynchronous motor is in line with the first efficiency standard in the provisions of GB18613-2012 "Minimum allowable values of energy efficiency and energy efficiency grades for small and medium three-phase asynchronous motors". Meanwhile, IE4 efficiency standard is also be satisfied in the provisions of IEC 60034-30-1:2014.
Improvement on design of efficiency is in line with the state's requirements on the energy saving and consumption reducing of the manufacturing sector.
YE4 series motors with the mounting dimension in accordance with standard IEC 60034, it has good features like, optimum structure, attractive appearance, low noise, high efficiency, high protection class as well as high insulation class. YE4 series motors can be widely used in various kinds of general use machineries like fans, pumps, machine tools, compressors, transportation and so on, and can also be used in the hazardous areas with oil and chemical, steel plants, mining industry.
YE4 series motors are suitable for almost all applications and operate satisfactorily at temperature from -15° C to +40° C and the altitude is not more than 1000meters.
◆ Temperature andinsulation
155(F)classinsulationsystemandtemperature rise class B (80K) are adopted to the motor, which increase the motor useful life andreliability.
◆ Cooling andventilation
The standard cooling method is totally Enclosed Fan Cooled (TEFC) in accordance with IC 411 of IEC 60034- 6. Standard motors are equipped with centrifuge plasticfans.
◆ Protectionclass
The standard protection degree of motor is IP55, which make moist and dusty condition is also allowable. Higher degree of protection is also available according to customer’s requirement..
◆ Motorprotection
The protection and measurement equipment to Winding and bearing such as PTC, PT100 are available on request.
◆ Voltage andfrequency
Standardvoltageandfrequencyis380V/50HZ, 200-660V special value on voltage and frequency is available on request. The motors will operate satisfactorily with variations of ±5% from the rated voltage.
◆ Quality assurance
Stringent quality procedures are observed from first design to finished products in accordance with ISO9001 documented quality systems.
