Motor Specifications – Voltage,Ampere and Frequency

These parameters are important to clarify our application design from voltage value,phases,full load ampere, overload setting and frequency setting if using Variable Speed Drive.

As an electrician,we must fully understand what is mean by voltage, ampere and frequency to ensure our application safe and working properly.

Ok…let we start our discussion and explanation about Voltage, Ampere and Frequency on Electric Motor Nameplate.


What is Rated Voltage?For simple understanding, rated voltage is manufacturer design for suitable operated voltage value with optimal performance.We can refer the motor voltage and phases on the nameplate also can decide either voltage/phases is available in our installation or not.Every country have different value of voltage.Please make sure your motor are followed standard country voltage.

Electric Motor Specifications

As we known,electric motor is an electrical equipment that convert from electrical source to mechanical energy and create rotating force.For Electrician or Electrical Engineer,to choose a right motor specification for installation or equipment is important and it’s critical decision have made.

We must know all about electric motor specifications to suit for our application.All important parameters or specifications  that we need for our application design must suitable with electric motor that we want to install to avoid any damage or failure during operation.

This time I would like to share about Electric Motor Specification that we must understand before we select or purchase new motor for our installation or project.How we can found about electric motor specification? Read More

ACTI 9 Miniature Circuit Breakers by SCHNEIDER ELECTRIC

Schneider Electric is the one of my favorite brand for electrical protection device.This time I want to share information about one of the Schneider Electric product.It is DIN rail modular Device- ACTI 9 Miniature Circuit Breaker by Schneider Electric.

DIN rail modular device have several range of products.Actually I want highlight about  miniature circuit breaker ACTI 9 device that used widely in low voltage electrical installation.

Schneider Electric produce the high quality products with advance technology for low voltage circuit protection like Miniature circuit breaker (MCB).That why I always choose products from Schneider Electric to my electrical installation. read More

How to use three phase motor in single phase power supply

This time,I would like to share some important knowledge that I used it when faced emergency or critical situation.What are you doing if have only three phase motor and single phase power supply available?

How to use three phase motor in single phase power supply?Actually three phase motor can operate in single phase power supply  with the help of a permanent CAPACITOR.This small thing (capacitor) very helpful to make three phase motor running in single phase power supply.

As per our last discussion about three phase motor,normally it’s have two(2) common winding connection ,STAR or DELTA connection.In this post,I explained how to wiring the capacitor in three phase motor,how to change motor rotation,how to estimate value of capacitance and selection of suitable capacitor.

Selecting a suitable generator for your application- Part 2

Last time,on my post “Selecting a suitable generator for your application – PART 1”,I’m promised to continue discussion about selecting a suitable generator for your application.In this post, I explained details and shared some tips to get a suitable generator for your application.

What’s this THD?

For ensuring smooth and continuous running of generator it is important to measure its THD –total harmonic distortion. When a significant portion of the load on a generator (or any power source for that matter) is non-linear, all the loads fed by the source will see this distortion. read more

Selecting a suitable generator for your application- Part 1

Ever tried to buy a generator? No? Then, you are saved a potential existential crisis, by God’s grace!! Ask someone who has tried to buy and actually landed with one.

And, he or she would tell you about the trials and tribulations involved in the process. It’s like trying to decode the proverbial riddle: horse before the cart or the cart before the horse!

Do you need a standby generator, single-phase, three-phase, kW, KVA, welder, or motor starting generators? Or, do you need a diesel run or a petrol run generator? read more

General Requirement For Motor Installation

Electric motor is the common application equipment in domestic or industry.If we have a knowledge and good guideline how to selected and install with proper way,It’s can smooth our installation project progress without any problem.

Motor selection and method of installation must suitable with our application to avoid any problem or design error.That why before installation we need have a design review with Electrical & Mechanical Engineer.This time I want share some information about requirement for motor installation that I hope it can gave some basic guideline how to handle motor installation project. read more
