Understand how the moment of inertia influence on the electric motor

If the electric motor has a coupled rotating mass at one point inertia is equal to that of the electric motor, the reversing times and departure and therefore, there are losses when it is compared the electric motor time to empty, tends to be double.

The original thermal equilibrium electric motor may be restored when there is a reduction in the number of reversals by 50%. The relationship between the time of the empty allowed and permitted load with reversal of time reversal usually occurs when it is equal to the relation between the moment of inertia of the electric motor and the moment of total inertia.

The inertia factor is the ratio between the total moment of inertia which is referred to and further to the electric motor shaft and where there is the inertia of the electric motor.

Electric motor performance characteristics must be carefully assessed

Two of the most important points to consider in the use of an electric motor are the selection and application of the electric motor. These two points are important because they involve many factors that relate to the installation, operation and maintenance.

Factors such as altitude, ambient temperature and ambient atmosphere are also aspects to be considered.

In addition to these, the engine performance characteristics must also be assessed. The most important points to be evaluated in electric motor baldors at best price performance are: the rated power, speed, speed (RPM) or the number of poles that the electric motor has; conjugates that can be nominal, maximum, minimum and locked rotor; the yield; the power factor; the chains may be blocked or nominal rotor and the electric motor operating conditions that may be continuous or intermittent basis.

The electric motor performance characteristics are usually available in electric motor catalog.
