The power that an electric motor provides within its characteristics is called nominal power. The nominal power concept is closely linked to the winding temperature rise. The electric motor will be able to drive loads of powers much bigger than its nominal power, until reaching the maximum conjugate.
If this overload is too high, when the engine is too high, the normal heat will be exceeded by shortening the engine life and may burn quickly. We can understand that the power requested to the motor is defined by the characteristics of the load, regardless of the power of the motor.
An electric motor SUM76004-4 should be supplied to the machine in which it is coupled and it is recommended that we have a margin of slack, as small overloads may occur and are common, and depending on the service regime, the motor will be able to supply the power.
The correction of the power factor is the increase of this factor, carried out with the connection of a capacitive load, will generally be a capacitor or super excited synchronous motor, in parallel with the load.
Reactive power is the portion of the power that “no” performs work, and it is only transferred and stored in the passive elements, such as capacitors and inductors.
