Motor Specifications – Voltage,Ampere and Frequency

These parameters are important to clarify our application design from voltage value,phases,full load ampere, overload setting and frequency setting if using Variable Speed Drive.

As an electrician,we must fully understand what is mean by voltage, ampere and frequency to ensure our application safe and working properly.

Ok…let we start our discussion and explanation about Voltage, Ampere and Frequency on Electric Motor Nameplate.

RATED VOLTAGE (VOLT)

What is Rated Voltage?For simple understanding, rated voltage is manufacturer design for suitable operated voltage value with optimal performance.We can refer the motor voltage and phases on the nameplate also can decide either voltage/phases is available in our installation or not.Every country have different value of voltage.Please make sure your motor are followed standard country voltage.

Determining electric motor load and efficiency

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.

The causes of electrical motor insulation failures

Basically electrical motor have a phase to phase winding coil around armature to created a magnetic field.To avoid shortage between phase to phase winding,the insulation systems needed.

It consists of the groundwall insulation and turn to turn insulation. Typically for induction motor insulation is the slot of paper to protect between cooper and ground surface.For phase to phase insulation normally used sheet of insulation paper laid between phase. read more

Types of Molded Case Circuit Breaker MCCB

Before we make a decision to install Molded case circuit breaker for our application,firstly we need to know about types of MCCB.It important information that we must know to make sure our MCCB can functioning properly to protect our application from electrical failure.

As we know the main function of MCCB are to protect our electrical application from short circuit or earth leakage and overload current.Manufacture have a their own design and types to suit domestic and industrial application.

To make a right selected for MCCB,the key point is to know what is our application or system and what protection we needed to install.After that,we can know which one of MCCB types we need for our application. read more

Terminal connection for induction motor

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
