Induction motor parts by parts

Controlling something using my PC was one of my biggest dream. I have studied a lot on how to do that and finally with the help of Labview I have controlled LED blinking, LED intensity control, LED intensity control based on LDR value etc. on 2018 last quarter. Followings are the expertise I have gained in between 28 August 2018 to 02 September 2018 (On a 5 day streak). A.      How to configure Labview to work with Arduino board B.      Basic of Labview studied C.      Arduino Digital output programming by Labview D.      Arduino Analog output programming by Labview E.       Arduino Analog output based on analog input by using Labview F.       Case structure and While loop using in Labview G.      Data flow analysis, Sub-VI, Case structure, array analysis H.      Comparison of value event analysis Refering these expertise, it was a great enjoyment for me to work with LabVIEW. I wish one day I cauld get job, where I will get chance to work with LabVIEW. Anyway

The main testing parameters are noted down below. 1 to 3 no's are most Frequent test. While others are usually tested by steel supplier or R&D purpose by the motor experts. Hysteresis loss and eddy current loss in separate value. Permeability of the punched sheet. B-H curve generation. Maximum polarization Effective polarization Maximum field strength Effective field strength Remanence Coercive field strength Specific apparent power Hysteresis display Form factor J(H) values for graphic display Among them hysteresis & eddy current loss is namely core loss and it checked as regular checking parameter before giving to stator line feeding. Usually core loss value is checked in each roll of stator lamination from the Press punched lamination. There are 3/4 total renowned tester supplier worldwide. 

Round enamel wires specification should follow the boundary condition stated below- 1.      For copper wire  : a). Material : Round  wires  made  of  copper,  insulated  with  Polyester  or  Polyesterimide  Enamel and covered with Polyamidimide; copper material according UNI EN 1977 ed 06-2000 Cu-ETP 1-CW003A.

Material : Round wires made of aluminium, insulated with Polyester or Polyesterimide Ename

There are special grade of silicon steel used in hermetic compressor motor. As because the motor performance should be high enough to meet the requirement of compressor COP, we electric motor designer always prefer to use steel with low watt/kg (core loss) value. But, certainly we should keep in mind about the exponential price rise along with the core loss value. The range of core loss value can be allowed in the range of 1.85 to 2.5 watt/kg at 1 tesla.
