The enclosure protections of this series of motor are IP44, IP54 and IP55 in accordance with the standard of GB4942.1 and IEC34-5 Enclosure Protection Levels of Rotating Electrical Machine.
The cooling method is IC411 in accordance with the standard of GB/T1993 and IEC34-6 Cooling Methods of Rotating Electrical Machine.
The structure and Installation method of this series of motor is IMB3 (horizontal with footing, end cover without flange) IMB5 (frame without footing, end cover with flange), IMB35 (frame with footing, end cover with flange), which complies with the specifications of GB997 and IEC 34-7 Motor Structure and Mounting Type Code.
This sample table lists the technical data and installation sizes of 380V level series motor, and may derive the 440V and 660V level motors in all sizes.

Application RangesThis 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 -15ºC;
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 serie motor's squirrel cage rotors adopt 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 generally 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.

Starting of Squirrel Cage Type Induction Motor
The rotor of induction motor has adopted the advanced computer technique to calculate the temperature and pressure of the squirrel rotor, thus to avoid the motor's destroy at an early period because of the motor's overloaded while starting. So we suggest users to check the items as belows:

1. The moment of inertial (after being converted to motor's rotating speed) of the rotating part of the driven mechanical equipment should not over these values of (loading J) item shown in the technical table;
2. Customers should guarantee the voltage of electric network across the motor's terminals not lower than 85% of the rated value during starting;
3. The resistance moment feature of driven machines is the resistance moment feature of water pump and fan.

Under the above mentioned conditions, motor may be permitted to be started at actual cold condition for twice continuously, or at hot condition for once, the interval of two times starting is natural stoppage. If there is need to start over limit, it must wait for one hour.
If the moment of inertia of the mechanical rotating part of the driven machinery is over the value shown in (loading J) item of technical data, or there is a requirement to start motor frequently, or it is possible to start the motor under heavy loading, it is necessary to contact with our company for negotiating about specific design so as to ensure the reliable start-up of motor.
