Factory View
Product Description
IE2/YE2 series three-phase asynchronous motors are high-efficiency three-phase asynchronous motors, which are produced in accordance with the national GB18613-2020 "Functional efficiency limits and energy efficiency levels of small and medium-sized three-phase asynchronous motors" and the relevant industry standards. The efficiency standards of YE2 series motors meet the national requirements of energy efficiency level 2 and are consistent with IEC60034-30, and meet the national requirements of evaluating values of energy conservation for motors.
Applicable scope: General-purpose places that need energy conservation and continuous operation, such as fans, pumps, etc.
Applications
This series of motor may be used for driving all kinds of general machines such as the compressor, ventilation fan, water pump, stock-removing machine, transportation machines and other mechanical equipment, and are applied as the prime mover in all industrial and mining enterprises such as the mine, machinery, petrochemical industry and power plant, etc. If the users place an order for the motors that are used for driving the machines with huge rotary inertia such as the blower, coal grinder, rolling machine, crusher, belt machine, etc., they shall provide us with relevant technical data, sign the technical agreement with us as the basis for specific design of motor to ensure the reliable operation of motor.
Normal operation conditions for motor:
1. Sea level is not over 1000m;
2. The highest ambient temperature is not over 40ºC, The lowest ambient temperature is -20ºC;
3.In moist month, the monthly overage highest relative humidity is 90%, at the same time, the monthly overage lowest temperature is not over 25ºC;
4. The frequency of power source is 50Hz±l%;
5. The variation of work voltage is not over rated voltage±5%;
6. Motor rating is continuous operation system SI.
Construction Description
The frame and end-shield of this series motors are made of cast iron; the stator employs the external pressing structure. Stator winding (H315, 355) is composed of flat copper formed hard coil or circular copper soft formed coil; the winding is made of class F or H insulation; the fixing of winding terminals employs the reliable special binding process. The whole stator employs the vacuum pressure impregnation class F solventless paint (VPI) for treatment. Thus, the motor has the excellent and reliable insulation performance and damp-proof and shock resistance.
This series motor's squirrel cage rotor adopts cast-aluminum rotor running reliably. The wound rotor adopts F class insulation material, and employs the vacuum pressure impregnation class F solventless paint (VPI) for treatment.
The motor employs the rolling bearing structure and the basic protection class is IP55. If the motors have higher protection class, the bearing protection class will be increased accordingly.
The H 315~355 series motor has the special oil filling tools may be used for filling and exhausting the oil without stopping the machine.
The main terminal box employs the sealed structure, and the protection class is IP55. They are installed in the motor's right side (view facing shaft end of the electric motor). It also can be installed in the motor's left side according to the requirement of users. The box has the separate grounding terminals.
