Understand the protective mechanisms of the electric motor compared to a short circuit

When installing an electric motor, the ideal is that a protective system is followed which aims to protect the electric motor.

The power network where the electric motor is installed must be against occasional short circuit in the electric motor, as this will ensure that in case of short circuit, the electric motor does not suffer from this problem.

The electric motor can not also suffer from excessive heat, as this may cause the electric motor to burn or premature shortening the life of the electric motor.

To protect the short circuit electric motor is important to make use of fuses that are delayed action because they protect the electric motor efficiently and cost is very low.


The magnetic circuit breakers also protect the electric motor short circuit, but they have a higher cost, they are resettable and need not be replaced.

Meet the electric motor service system

The rotor current – blocked is the maximum effective current value showing stable conditions that will travel the electric motor stopped when the electric motor is powered at rated voltages and frequencies.

The NBR 17094 shows maximum values of current to the locked rotor due to the function of the rated power of the electric motor.

The indication of the locked rotor current is the electric motor JM3120 1.5HP nameplate is held directly and points out the value of the relationship between the starting current relative to the rated current.

The service system is the system that the electric motor is subjected when the electric motor is running and it covers the ranges that are empty, at rest or no power over their durations and sequence it in time. The electric motor is designed to operate on a continuous basis.

Synchronous electric motor

Synchronous electric motor is not used much because it has a high operating cost

The electric motor’s main function perform transformation of electrical energy into mechanical energy and for this reason, the AC electric motor is always the most used, because the way the engine power transmission happens is alternately. But the synchronous electric motor is used when you need a lot of power or the working speed does not vary, but this kind of electric motor has a high operating cost.

The electric induction motor has AC MagPowr DFP-2 and is simple to build, it is robust and has a low operating cost, so it is the most used. Its speed is always constant, but may vary slightly when the load is on the shaft. The induction motor enables the speed to be controlled with the aid of frequency converters.

Electric Motor Parts

To find parts for electric motors would be interesting if you’re looking for specific stores, whether online or physical. It has many companies specializing in this. Only the most exclusive pieces is that they have more affordable. In addition, they may also be missing in stock.

Finding parts for electric motors requires research in the market, as well as any other service that you are purchasing. You must preferably for stores that offer cost and more affordable benefit to the product you wish to purchase mrosupply ts 150 magpo. This will require you to search and compare.

Parts for electric motors is not difficult to find, but those most exclusive parts ended up not being present in most stocks of stores. This does not prevent you get your, you just make a request, it will take a little longer to reach, but worth it, especially if you are in need.

Brazilian electric motor has been modified to save energy

The electric motor is largely responsible for making the world to develop and change the technological progress of the world. The electric motor has changed people’s lives and today the electricity is also used in favor of people’s needs. The electric motor was the invention that helped to make the world continue moving both economically as social way.

The electric motor produced in Brazil was subjected to change to meet the energy efficiency of the whole world. Thus, these driving machines will make their income levels were increased.


The purpose of submitting the electric motor all these changes is to make it more efficient and save more electricity. The electric motor consumes a lot of energy because the electric motor is responsible for making the electrical energy is transformed into mechanical energy and so it goes into operation.
