Parts of induction motor

Large Electrical motor consist of many part these are:

Stator : 

Stator is main part of induction motor made up assembly of many silicon steel sheel. Silicon steel sheet are used to removed eddy current loss. Winding coil is mounted on it 
It is static part of induction part. 


 



Rotor :

Rotor is rotating part of 
Induction motor it is also made up assembly of many silicon steel sheet. Some rotor are wounded by copper rod and short circuit by end ring. 




Radiator :

Radiator are generally used in water cooled induction motor. To reduce motor from over heat two radiators are assembled in motor and connected with permanent water supply. 


Blower :

Blower is used to blow air for cooling of motor. Blower generally used in air cooled motor differ from water cooled. One side of motor connected with blower and another side is connected with silencer to reduce noise of air blower.

 Copper Rod /coil :


Copper rod and coil is very important part of motor used for winding. Copper rod/coil is conductor of electricity. Copper rod or coil is used for two type of winding lap winding and wave winding. Electric current flow in copper winding make a magnetic flux which generate torque used for rotor rotating.

RTD (Resistance temperature detector) :

RTD is a platinum rod which is fitted under each winding in stator of motor. It is high temperature detector thus it is used for resistance temperature rise of motor
RTD consist of length of thin wire wrapped around around a cremaic or glass core

BTD : Bearing Temperature Detector:

It is same platinum rod little bit thicher than rtd it used to to detect bearing temperature rise of electrical motor 
 

Bearing : 

It is very important part of motor which is used to hold motor shaft and provide smooth rotation 
According to the motor Power and capacity various types of bearing used these are 
1. Ball bearing - it is used for small domestic motor 
2.Roller bearing - it is used some bigger motor to hold more load and rotation 
3. Tapered roller bearing - it is mostly used in slip ring induction motor 
4.sleeve Bearing - it is used for very big industrial motor providing permanent oil supply to the bearing.

Three phase induction motor is made up of which metal

Image
  Metal required for making induction motor :- 1. Silicon steel metal sheet -     Silicone steel is used for making rotor and             stator of induction motor. Many sheet                   connected together to make rotor and stator       to reduce eddy current loss. 2. Mild Steel -       Induction motor shaft is made up of mild              steel. 3. Copper -       Winding Rod or wire of induction motor is              made up of copper it is very good conductor         of electricity. 4. Cast Iron -       Outer Body or casing of motor is made from          cast Iron.

What is IP ratings in Electrical Motor

Image
What is IP Enclosure Ratings and standard in Electrical Motor   *. IP ratings defined as Ingress protection or international protection ratings        ( BS EN 60529 : 1992) *. This standard used to define level of sealing        effectiveness  of electrical enclosure against     dust, dirt, moisture, water etc * What is two digit in IP ratings.  It is consist of letter IP followed by two digit. Higher the number better the protection if number is replaced by X it means it is not rated for that specification     * IP65   =  First Digit – Solids       The first  digit of IP indicates the level of protection that the  enclosure  provides  against the  ingress of solid foreign objects, from tools or fingers that could be  hazardous if they came into  contact with electrical conductors or moving  parts, to airborne dirt and dust that could damage c...
