When we plan to install an electric motor for our application,the one of important parameter that we MUST verify is about VOLTAGE.Ensure the voltage is balance between phase to phase. Motor voltages should be kept as close to the nameplate value as possible, with a maximum deviation of 5 %. Normally motors are designed to operate [...]
Breakdown causes by electric motor failures always happen in our operation due to of 2 major factors.It is Mechanical component defect and Electrical circuit failure. Typical instruments used for troubleshooting motor operation problems include a Multimeter, Clamp-on Meter,Insulation Resistance Meter, and Infrared Thermometer. These instruments are used to measure voltage,current, resistance, insulation resistance, and temperature. But when [...]
How many second we need to setting for changeover timer from STAR to DELTA sequence for Star Delta Starter?This question is very popular among electrician around the world when handling the Star Delta Starter for their application. From my experience,honestly,it quite difficult to get the accurate times for star delta changeover.But we can get the approximate times [...]
The main purpose of this 16 steps is to look at the systematic and proper work sequence on disconnecting the wiring,check the motor nameplate, specification when replacing the motor until complete the task. I would like to share my routine standard procedure for replacing a new motor.I created this procedure follow the safety guideline and reference from [...]
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 [...]
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. [...]
Star Delta starter is the most widely used application especially for Air-compressor and HVAC system.This starter used for 6 or 12 wire for motor terminal depend on electric motor that chosen for the application. Basically this starter used 3 unit contactor,1 unit timer delay,1 unit overload relay and start/stop button to control the star delta [...]
