Dual voltage motor

17/06/2011 by 18 Comments

If we take a look at electric motor nameplate,we can see the several important information and specification about electric motor.This time i want explain about dual voltage for power supply.

It is like a simple thing and not so important BUT if we make a mistake about electric motor voltage power supply,it can cause the winding damage and burn out.That why i would like to share about this information to avoid serious damage for electric motor.

The reason why motor manufacture design dual voltage is to make this motor available for any country used because every country have a different voltage value such as 200 VAC,600 VAC and 415 VAC.It also so for marketing strategy to increase their profit margin. read more

Motor cooling

13/06/2011 by 4 Comments

Electric motor generated the heat from inductance process.So the temperature is important factor to ensure the electric motor can operated smoothly without any problem.

Heat can effected the efficiency of motor,maximum load capacity,duty cycle and winding lifespan.That why heat from motor operation must be controlled by motor cooling.

How to control temperature for electric motor?The best method is with motor cooling system.Basically heat generated during motor running will be transferred to the ambient air surrounding. read more

Belt drive

12/06/2011 by 2 Comments

Drive method is a important for rotating equipment or machine operated such as pump,blower,fan,vacuum,compressor,grinder,turbine and others.

Several kinds of drive method we can found and it design depend on application or types of work load.One of common drive used for equipment is a belt drive.manufacture design many type of belt to ensure it suitable with any application.

The advantage of belt drive it is relatively efficient and readily available. We also easily setting the speed of drive with selected a combination of pulley size (ratio) with electric motor speed (RPM). read more

Sizing for magnetic contactor

07/06/2011 by 12 Comments

When we design or replaced the magnetic contactor for motor starter or for others application,the important point is how to sizing the size of magnetic contactor.This is critical point because if we not sizing properly,it can cause a serious damage and our application maybe failure to perform in perfect condition.

This time i want  shared some information and basic technique how to sizing the magnetic contactor with properly method and suitable with our application needed.It is to ensure our application design is correctly function and have a good resulted. read more

Terminal connection for induction motor

09/04/2011 by 28 Comments

When we install a new electric motor for our application,we need to determine the voltage of power supply.Why it so important when we dealing with electric motor?

Ok..electric motor manufacture design their product can suit with several value of power supply around the world.It made the motor can used at any countries without worried about their power supply value.

The value of voltage for all country’s around the world have variant such as 200 VAC,220 VAC,415 VAC or 440 VAC  for 3 phase.That why some motor manufacture design their motor can operated with 2 types of voltage.So it available for use to any country around the world. read more
