What is HI-POT tester? When we need to evaluate 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 [...]
Star Delta completed wiring diagram 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 [...]
DC motor starting information. 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 [...]
What is dual voltage for electric motor? If we 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 [...]
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 [...]
Some people do not concern about the correct method to storage the electric motor.This matter look like simple and easy but if we not take serious action,it can cause serious damage and involve high cost for repairing when electric motor defect due to not proper storage method. I hope my post this time can make [...]
On my last post,i already showed my video about how to install soft gland packing seal for water pump.This time i want share some information on my video how to install water pump complete with alignment. This is common technique for maintenance person to install back the water pump to electric motor.To operated water pump,we [...]
Why measurement of insulation resistance so important? This measurement important to determine the winding condition for electric motor,electric cables,electrical installation,transformer,circuit breaker,heater and electrical equipment.From the data of insulation resistance,we can make a perfect and clear decision either the electrical equipment in good condition or not. The insulation resistance testing also can avoid serious damage,fire or [...]
