Electric motor slot frequency is also classified as a basic frequency

The electric motor slot frequency is also classified as a basic frequency.

The electric motor of the air gap slots occur in the stator and the rotor, because they generate vibrate when they create an imbalance of the forces that are magnetic in attracting and the consequence is the result of the variation of reluctance that appears in the electric motor circuit driven by function the rate of passage through the slots in both the stator and in the rotor.


To measure the vibration of the electric motor is necessary to take into account the structure of the machine that acts as a buffer and thus it is possible to measure the rotor vibration in the electric motor by means of sensors that have no contact.

Machines with rotary assembly and lightweight structures that are robust and heavy and also has the majority of forces generated by the electric motor rotor when there is relative movement between the shaft and the bearing.

More used electric motors

Difficult to define what type of electric motor used more time, that because there is a wide variation of these machines and they are present in an increasing number of segments. It is interesting to have knowledge about what are the areas that this engine can meet, so that we understand the importance of it.


The single-phase and three-phase models are among the most used. Final applications are huge and the engine now has its importance both in the industrial sector, but also in the commercial. Since that lift you use up to numerous apparatuses equipment, all this moves through the engine functionality.

The function of this motor will convert electrical energy into mechanical energy. This functionality can meet the needs of various customers and also various processes. It also has who innovates and tries to electric motor at home, these are best suited for small experiments and are not difficult to set up.

Electric motor with power up to 100 kW

Electric motor with power up to 100 kW must follow the ABNT magpowr c-10

The electric motor has power up to 100 kW according to ABNT NBR 17094-1 indicates that the electric motor should have a grounding terminal inside the terminal box, as it allows for a protective conductor connection or grounding conductor and thus the electric motor with power over 100 kW must rely not only on the ground inside the junction box over to a fixed terminal on the housing.

The electric motor WEG has developed a superior way the norm and therefore, all carcasses have a ground terminal placed in the connection box and a second in the adjacent housing to the junction box.

When the model of carcasses is 225S / M to 355 A / B has two additional ground terminals that are provided to be equalized the electrical potential of the electric motor and provide greater certainty for operators.

Hammer should not be used in electric motor bearings

The electric motor suffers a lot with problems in their bearings. To combat this, it is important that the electric motor bearings undergo a periodic inspection, as well the electric motor will be free of noise, vibration and lubrication system will always be on time.

By introducing the electric motor bearings on the shaft it should be done with the aid of a press with support on the track from inside the bearing, or even by heating in an oil bath or by equipment that is heated by induction.

miter gears where to buy

The hammer and no other device giving blow should be used in the bearings, because despite bearing endure high loads that are always constant, the electric motor is very sensitive to pulsating loads, because their spheres mark the circulating path and thus causes deterioration is rapid and there are also waste electricity.

Electric motor operation

Electromagnetism is used in the operating principle of the electric motors. These engines have evolved in recent years and today we have many kinds that I will meet the varied purposes. Who studies the electric motors knows how important they are for various segments, especially the industrial segment.

This machine will receive power and make the conversion to mechanical energy. It is the mechanical energy responsible for giving motion to the process where this driver. This function is the same for both industries, as well as for equipment which we use daily.

To give you an idea, the electric motor is even used in elevators. The latest studies are trying to bring this machine to the automotive industry, because it seems a more favorable economy and maintain than traditional methods being used.

The various commercial and industrial segments have used the feature provided by the electric motor, we can clearly see how it has expanded.

Electric motor models

Since its inception, the electric motor has undergone significant changes and that contributed to its evolution. Today we have different types and models of electric motors pump motors jm31, the intention is that the machine is present in very different segments and it has become increasingly true.

The models electric motors are there to show how this machine has changed significantly. Today he can be present in single segments and also in more complex segments. Its function is always the same, to the transformation of electrical energy into mechanical energy, very important this functionality to applications.

Who is making the purchase of an electric motor have to analyze well the ideal model for the desired application. Today the price is set according to model and also the brand, so it is very important to have these aspects defined so you can buy the right machine for what you need.

Learn about common problems of the single-phase electric motor

As the three-phase electric motor, single-phase electric motor can also burn for several reasons and among these reasons are: short circuit between the turns of the main stringing.

The electric motor can suffer from the short circuit between the turns of the main stringing, because there may be a failure in the enamel making wire insulation, impregnating varnish was placed poorly or electric motor has its contaminated inside.

The problem may also occur in the turns of the auxiliary electric motor winding, as they may also have short circuit reason also for failure to enamel that makes the wire insulation, impregnating varnish was placed poorly or the electric motor had its contaminated inside.


The electric motor can also suffer from half the superheated electric motor winding and it can be driven by the fault on the switch voltage switch when the switch is positioned on the lower voltage when peak loads reach cause occurs the closing of the centrifugal switch and thereby the electric motor is powered by platinum higher voltage or when only half of the firing signal winding is that it is not placed in parallel with the auxiliary winding.

Manual Electric Motor

You will find the electric motor manual on the product you purchase. In the event of the loss or damage of the document you may be finding another option over the internet. The most important is that you have is that document because it will be necessary for various purposes. eletrical transformer t2535

Usually people use the electric motor manual in order to address some questions regarding functionality, maintenance or even mount this machine. So that the document is very important and even indispensable for professionals to work properly with the electric motor.

On the internet you can also find different types of manual so that you can use. See which one is most suitable for the engine that you are using. You have several options, but the ideal would be to use the manual that is motor itself that you purchased. Just get another if it does not find the original.
