The main purpose of motor enclosure is to provides protection from environment impacts such as rain,corrosive,rusty and many more in which motor installed.
This protection can make motor more life span and can running in suitable condition.It also provide a types of cooling system for a motor depend on their types of enclosure.
Before we select a motor enclosures for our application,please review about location,types of environment impact and ambient temperature to avoid any mistaken. read more
As we known,the electric motor is the one of important equipment to drive the operation smoothly from beginning to end of product.
Electricity cost normally around 60% came from electric motor running.It become more worth if installed motors are oversized,low efficiency,under design,poor maintenance or mismatched.
So to know the actual motor performance, we need to determine electric motor load and their efficiency to eliminated all problems that can cause the high electricity cost and breakdown.
We need to collected several important data from our electric motor to made comparison and analysis about load and efficiency.
When we need to evaluate the motor condition,HI-POT tester or High Potential tester is the common equipment are used.As we know,a multimeter or ohm meter reading only can determine if a motor winding is open or shorted but cannot checked winding insulation condition if shorted with ground or phase.
The main purpose of the Hi Pot tester is to verify the quality and integrity of the electric motor insulation materials used on the armature or stator and also safe to using it without any defect.
Sometime we not take a serious attention or not know about it to checked winding insulation.This step is important to ensure motor can running in good condition without any breakdown. read more
The most active post in Electrical Engineering Centre blog is Star delta starter and Star Delta motor connection.I received many comments and request for Star Delta circuit diagram.
So this time i want share my simple star delta circuit diagram completed with power and control line circuit.I hope it can be as basic reference for all electrician about star delta starter diagram.
Star delta starter is a common used in domestic and industry sector to drive variant application such as chiller water pump,machinery,air-compressor and many more equipment. read more
DC motor is the one of common types of motor that used for industrial application.It have more advantage and suitable for more heavy application in industry.
This time i want share some basic information how DC motor starting.It important because from this we can know how to build and setting the controller for DC motor.
As we known,DC motor types such as fractional-horsepower shunt, series, and compound DC motors can be started by connecting the motor directly to DC line voltage. read more
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
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
