broyeurs hz de highfreqncy

Why we use 50Hz, 60Hz or 400Hz frequency? | GoHz

In actual applications, the high frequency will make the reactance increase, electromagnetic loss, and increase the reactive power. Motor, for example, the current will decrease greatly, the output power and torque will decrease evidently, which does not has any benefit.

Utility frequency - Wikipedia

The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in an electric power grid transmitted from a power station to the end-user.In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz.

CM - Frequency and Voltage Converters - Olivibra

Frequency and Voltage Converters consist of an electric motor coupled to a permanent magnet generator that reduces the single-phase (230 V, 1 ph) or three-phase (400 V, 3 ph) input voltage into one lower than 50 V increasing the frequency to 200 Hz, necessary for correct operation of electric internal vibrators, thus ensuring operator safety as occurs with low voltage equipment.
