How To Replace Bearing For Electric Motor?

With advance technology,we can found the root cause for abnormal sound using Vibration Analysis for rotating equipment.When vibration owner confirm that bearing are defected,we must plan to change or replace a bearing.This time I would like to share video completed method how to replace electric motor bearing.

This is common activities for Electrician to perform bearing replacement during daily routine or turnaround / shutdown.We must ensure all bearing condition for our electrical motor in good performance to prolong bearing life time and can avoid unplanned downtime that can increase maintenance cost.

How To Disconnect THOMAS Coupling From Induction Motor Hub?

Hi,

This post I would like to share video how to disconnect or dis-engage THOMAS Coupling from motor hub during maintenance works.In this video,technician plan to replace new bearing for the motor due to abnormal sound detected from bearing.Normally in industry or chemical plant,Thomas Coupling is the one of common application to connect electric motor as a drive and pump as a rotary equipment for the process.

The main reason why Thomas coupling are used :-

  1. To transmit power from one shaft to another, efficiently and effectively.
  2. To accommodate slight shaft misalignment which develop in service.

Thomas coupling application also can protect our equipment from mechanical damage and misalignment. Below several protection when using Thomas coupling :-

1. Absorb shock, vibration and pulsations.

2. Decrease cross load on bearings.

3. Accept load reversals.

4. Minimize backlash. Read More

How To Use Bearing Induction Heater ?

This post I would like to share a video How To Use Bearing Induction Heater.Normally when we dealing with bigger motor or pump bearing,it’s quite difficult to install bearing into shaft because a tolerance gap is small.If we use a bearing pusher to install bigger size bearing into shaft,it’s risky and probably percentage of bearing was damage is high.That why we must use bearing induction heater for more safe and easy bearing installation.

In this video, I used old version of SKF bearing induction heater but still working perfectly without any problem.For latest version and model of Induction Heater from SKF,please visit SKF website  Read More

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

General Requirement For Motor Starter

When we plan to install new motor starter,we need to consider a few requirement that we want to apply to get a best design,tidy and easy to troubleshooting if have any problem.

Normally motor starter component includes a drive (VFD),electrical wiring,control panel,communication system (Ethernet / Devicenet) and types of starter that we plan to use.

From the design stage,we must follow general requirement for Motor starter to get a best result for our installation.Below I listed some of requirement to build a motor starter.I hope it’s can give a clear view or guide line during design a motor starter. read more

Introduction of Servo Motor

In the industrial application for automation technology,Servo motor is the one of common used for high technology equipment that provided more efficiency and precision tune for movement.It’s have a rotary actuator that can make it have a precise control for angular position.

Servo motors have small diameter rotors for low inertia to provide a rapid response. They are fractional to small integral Hp in size and they typically have resolver or encoders to provide very precise speed and position sensing.

They are also almost always Totally Enclosed Non- Ventilated (TENV) enclosures.Below I had listed 3 types of servo motors that commonly used for industrial application. read more
