The basic operating principle of the electric motor is connected with the electromagnetic fields. For those unaware, this engine has the function of making the transformation of electrical energy into mechanical energy and for this it needs internal parts responsible for this function.
Today there are several types of electric motors single motors l509t baldor, but they have similar features. What is even change the size and strength of the machine, this because each will be suitable for a different type of end use, then we have many variations. The basic or complete operation is not difficult to understand, so you’ll have no trouble about.
From the moment in which the motor can convert electrical energy into mechanical energy it can be present in various end applications as well. When buying an electric motor is very important that the person knows what is the most suitable type for the desired application.
The electric motor’s basic function is to perform the conversion of electrical energy into mechanical energy. The better the electric motor, the better the conversion that the electric motor performs the transformation of electrical energy into mechanical energy.
When the electric motor does not work well, the losses occur by friction, losses short circuit. best prices for tension control magpowr
The friction loss is driven by mechanical characteristics of the electric motor when running on the bearings generating minimal friction possible and in practice it is not possible to reduce friction and so the losses occur.
The mechanical pressure that is suffering the brushes on the electric motor rotor causes friction losses occur as a brake and generate heat so that there is greater loss of income from the electric motor.
Losses due to short-circuit occur when the brushes change the contact and move from one winding to another rotation of the electric motor and the contact occurs in the two windings at the same time.
The supply voltage at which the electric motor is submitted should present a sinusoidal behavior called. It is common now that the electric motor is driven by electrical drives and these drives are the ones that cause the shapes of waves of voltage and / or current.
Because of the harmonics, the electric motor is no longer an AC classified as pure and it will cause losses there, reducing the torque that is available to the load and also the presence of conjugated called Pulsed. All this will cause the electric motor has problems such as heat, vibration, and drop in income.
The harmonics can cause the life of the electric motor is reduced because there may be damage to the bearings, shaft fatigue, or even deterioration of the insulation system.
Another factor that causes harmonics in the power supply are electronic devices that control the speed of electric induction motor.
