This sample table lists the technical data and installation sizes of 380V grade series motor, and may derive the 440V and 660V grade motors in all sizes.

Application Scope 
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 to drive 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.
The YR (IP23) series electric motor is capable of providing relatively large locked rotor torque under relatively small locked rotor current, and regulating speed within limits. It apply to the following situations extensively: (1) The larger locked rotor torque is required than squirrel cage type motors; (2) The capacity of transmitting line is insufficient to start squirrel cage type electric motor; (3) Long starting time and frequent starting; (4) The speed regulation is required within small range; (5) Synchronous rotation with Electrical Axis.formed by unity. Such as: compressor, presser, winch, bedrench, conveyor, printing machine etc.
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 frames and end-shields of this series motors adopts high rigidity casting iron, the stator employs the externally pressing structure. Stator winding (H315, 355) consists of flat copper formed hard coil or circular copper formed random coil. It employs class B or F insulating materials. the fixing of winding terminals employs the special binding process, fixed and reliable. The whole stator is treated by the vacuum pressure impregnation (VPI) F solventless paint. Thus, the motor has the excellent and reliable insulation performance, damp-proof and shock resistance.

The squirrel cage rotor in this series motor mostly adopts cast aluminum rotor, running reliable. The wound rotor employs the F-level insulation material and uses the vacuum pressure impregnation F-level solventless paint (VPI) for treatment.
The motor employs the rolling bearing structure and the basic protection class is IP23.
The motor (315~355) 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 IP54. They are generally installed in the right side of motor (view facing shaft end of the electric motor). It also can be installed in the left side of motor according to the requirement of users. The box has the separate grounding terminals.

Starting of Squirrel Cage Type Induction Motor
The squirrel cage rotor of induction motor has adopted the advanced computer technique to calculate the starting temperature and pressure of the squirrel rotor, thus 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 below:
  1. The moment of inertial (after being converted to motors 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 above limit, it must wait for one hour.
If the moment of inertia of the mechanical rotating part of the machinery being drive 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.

Certifications

We have obtained such certifications as CE, CCC, EAC, ISO 9001, ISO 14001, ISO45001, etc. Our motor series comply with IEC, NEMA, GOST, ISO, IEEE, JIS, AS standards.
