Equipment for PLC programming

25/03/2011 by 1 Comment

Now in automation industry,the common practice for programming the PLC is using a desktop or laptop.It easy to handle and more comfortable when perform the design or troubleshooting job.

PLC manufacture also in advance to produce a user friendly PLC software in market today.It made our programming task more easy and can get the best result and design for our project.Everybody can learn about PLC programming because it easy to understand and have many option functions for design,programming and fault finding task.

To ensure PLC programming done properly,we should prepare all equipment or tools for programming matter is available and working in good condition.

motor nameplate information #6 – Construction

15/03/2011 by 1 Comment

This information is very useful when we selected the electric motor.From this data we can estimate the type of motor and the suitable application to ensure it running full capacity and more efficiency.

This is a basic data that we can get from electric motor name plate.Normally it tell about enclosure,motor frame,and bearing.This information can make we easier to rectify any problem when motor is defected.

Example we can know the size and type of bearing used for that motor.We can know the information without dismantle the motor.Only from the nameplate of motor. read more

motor nameplate information #5 – Reliability

14/03/2011 by 1 Comment

This information is useful for troubleshooting and commisioning.It can tell us about the reliability of electric motor.We can design the area or room with such as good ventilation,enough space for maintenance works and suitable with motor application.

This information also can use for safety purpose.we can design the safety working area for that motor and can protect a user or operator from any electric shock or others danger.

The work load is important to ensure the motor can run efficient and not over their capacity.We must design the motor application suitable with working load. Read more

motor nameplate information #4 – Safety

13/03/2011 by Leave a Comment

Now in stater motor industry,their design a new advance technology for control a electric motor.In industry the Variable speed drive,soft stater and inverter very common used.It is very efficient and can save a electricity cost.

This time i want explain about safety information for electric motor.This information is safety certificate from third party.For more better electric motor design and function,the manufacture must alert about new technology for motor.

They can design a motor suitable with new technology of motor controller.It can make motor more efficient and can running in full capacity.The important thing is the motor can have more long life span. read more

motor nameplate information #3 – Performance

10/03/2011 by Leave a Comment

Last time i already discuss about Electrical input and Mechanical output parameters.This time i try to describe about performance parameter.Normally this parameter tell about motor efficiency,services factor and motor duty.From this parameter we can decide and design the system for efficiency motor.

We can determine the suitable stater such as inverter,VSD or soft stater to control the motor running operation.If motor can running in high efficiency,we can save a maintenance cost,electrical cost and improve productivity.

Here i explain detail about performance parameter that normally state on electric motor name plate :- read more

How to replace bearings for electric induction motor?

25/02/2011 by 6 Comments

For electric motor failure causes,the common defected for mechanical part is bearing.Normally 1 unit motor have a 2 pieces of bearing and type of bearing for induction motor is ball bearing full metal cover ( ZZ ).

Root cause for bearings problem usually such as rusty due to condensation process,ball in housing broken,grease was burn out,a ball bearing nest broken and overload or motor shaft connected with load is not alignment properly.

For electrician or maintenance person,this is a routine jobs and it is a compulsory skills for this person who involved in electrical motor field.

This time i want share my little experience how to replaced bearing for electric induction motor.Don’t worry, i explain detail step by step how it done in my video.I hope it can be a guideline  to do it yourself in actual workplaces. Read more

Usually the generator is designed to capable to delivery the power supply required due to time basic ( hour ) to ensure reliable operation and prevent serious breakdown.

Typically a given set can deliver more power for fewer hours per year, or less power continuously. That is a standby set is only expected to give its peak output for a few hours per year, whereas a continuously running set, would be expected to give a somewhat lower output, but literally continuously, and both to have reasonable maintenance and reliability. read more
