the nameplate of the electric motor

 Explanation of the nameplate of the electric motor:

1- (4 poles) the number of motor poles.

2- (1 horsepower) the horsepower of the engine, i.e. horsepower, and the horsepower is 0.75 kilowatts, and also to convert the horsepower to Watt, W, multiplied by horsepower * 746.

3- (0.75 KW) the electric power of the motor, which is its unit KW.

4- (50 HZ) frequency range from 0 to 50 Engine speed increases.

5- (1420 revolutions per minute), which is for aerodynamic engineering at its maximum speed at a frequency of 50 Hz.

law, which is equal to:

RPM = HP * 5250 / T.

6- (INS F) is called the Insulation Class, which is a letter indicating the degree of tolerance of an isolated case.

The following table shows:

7- (AMP 40C), which is the temperature of the medium at which the air varies.

8- (Cont Rating) The nature of the work of the electric motor is divided into many types, such as:

   It continues to operate efficiently for a long time.

   Intermediate, i.e. he works for a period and is separated for a period.

   - short time duty, i.e. he works for a short period, after which he must stop (and this period is written next to the type of engine) and others

9- (Bearing type) A number indicating the type and specifications of the bearing, a bearing that is installed in the electric motor.

10 - (serial number) And this is a number belonging to the factory to help identify the characteristics of the product.. and it does not help us in anything

11 - One of the most important information as it determines the voltage and current at which the engine must operate in its running state, Star and in its operating state.

Delta, and if these values ​​of efforts are not adhered to, the engine may burn out.

12 - (IP Code) is a code that determines the degree of protection of the motor m where dirt or water enters it.

13 - date of manufacture of the engine

14 - The weight of the engine .. It is very useful when you want to move it or lift it with a winch.

15 - A number indicating the dimensions of the engine.. There are tables that show the significance of this number.
