Troubleshooting guide when motor overload trip

On my last post,I’d discussed about motor overload relay that are common used for motor starter application.As we known,the main purpose of motor overload relay is to protect our electric motor winding from mechanical overload that can result the serious damage.

This time I want share basic guideline or troubleshooting method how to troubleshooting when motor overload relay trip.I hope this post can give some ideas or clear view when you face this similar problem during your routine jobs. read more

Basic of Motor Control

What is definition of motor control?This is familiar question from electrical person around the world.Motor control is common practice for machine application and industry operation.

Basically motor control definition is to STOP and START the electric motor.Technology and innovation of motor control is always developed to parallel with current application needed.

Motor control have a two basic methods.There is MANUAL control and MAGNETIC control.I describe detail about manual and magnetic control circuit diagram and basic operation. read more

Electric Motor starter method

Basically motor starter designed for asynchronous motors or induction motor is a mechanism  to start and stop the motor operation.It also provides over current,overload and short circuit protection during operation.

The main task is the starter motor to reduce motor starting currents,High inrush current and prevent the motor from operating when suddenly the power supply to be connected.It is for safety and to avoid serious damage of equipment or person.

Motor starter also capable to controlling the forward reverse rotation, speed motor, braking and various other duties as appropriate.In industry,motor starter very common used to control of equipments and application using electric motor for production or any process. read more
