20-90 ASPECTE ENERGETICE LA ALEGEREA UNEI ANTRENĂRI ELECTROMECANICE

ENERGETIC ASPECTS AT THE CHOICE OF AN
ELECTROMECHANICAL DRIVE
This paper estimates an important criterion regarding the choice of an
electromechanical drive: energetic efficiency. The efficiency of the driving
system is analysed taking into account the transformer and power network,
frequency converter, motor, a belt transmission, a gearbox and the coupling
between the gearbox and the driven machine.

21-56 MULTIPLICATOARELE INSTALAŢIILOR ENERGETICE EOLIENE ( II )

MULTIPLIERS OF THE WIND TURBINES ( II )
This paper emphasizes the changes appeared in the technique of the
wind turbine driving in the last two decades.
Three schemes of multipliers used now are presented and the
calculus elements are done allowing the structural optimization of these
transmissions.
