The "Lenze Drive Package" stands for efficiency
Hamelin/Hanover, -- Higher levels of performance and dynamics for less: thanks to the combined decentralised 8400 motec frequency inverter, brand new three-phase AC motors and high efficiency gearboxes, Lenze has been able to offer an impressive L-force drive package. What will bring music to purchaser's and ROI calculator's ears: the "Drive Package" handles energy extremely economically.
The new MF L-force three-phase AC motors outperform the minimum degree of efficiency of class IE2 and as a result of their special design are able to fully utilise the options provided by frequency inverter operation for the first time. As such, the frame size can be reduced by up to two levels for the same output power. When compared with conventional three-phase AC motors, a significant increase in performance is observed, due to the high degree of energy efficiency as well as the compactness and dynamics which are characteristic of servo motors. In essence, the latter is the result of lower mass inertia, due to the lower axis height with the same performance level. The moment of inertia which is lower than that of standard motors further reduces the energy consumed in the case of speed variations.
The "Drive Package" means that you can take full advantage of the benefits of optimised three-phase AC motors in one complete drive system. With this in mind, the decentralised 8400 motec frequency inverters mounted on the motor and the directly fitted right-angle or coaxial gearboxes deliver compactness in the first instance together with energy efficiency. In addition to the high efficiency of the gearbox and motor, the 8400 motec intelligently adjusts the magnetising current, this is performed in VFC eco mode. Particularly during partial load operation, three-phase AC motors have until now been supplied with a higher magnetising current than is actually required for operation. The VFC eco operation, on the other hand, now adjusts the magnetisation of the load and thereby reduces the energy demand of the "Drive Package" by up to 30 percent.
