8400 motec drive packages by Lenze

By the use of frequency inverters, electrical energy can be converted to motion in an especially economical manner – in particular directly at the process. Since by means of decentralised drive technology functions can be transferred to where they are really needed, such solutions create real added value, especially in expanded systems of assembly technology and handling technology.

A high dynamic performance, energy efficiency, and power density: With the 8400 motec drive packages, Lenze has succeeded in putting together some extremely compact drive packages. For this purpose, the specialist for drive and automation technology cleverly combines his new inverter-optimised L-force three-phase AC motors of the MF series, highly efficient gearboxes, and the 8400 motec motor inverters which are also new. Inverter operation provides the basis to increase the motor power with a higher speed. The high ratio of the Lenze gearboxes on its part provides comparable torques. This drive solution is rendered possible because the gearbox input pinion is pressed into the motor output shaft in a friction-locked manner via taper interference fit – a Lenze speciality – and because it can therefore be considerably smaller than a gear wheel placed on the shaft.

Altogether this constructive finesse produces a size which, measured from the centre of the output shaft, is just as great as a standard motor directly coupled to the mains with a comparable power. Hence the mechatronic units can be very easily integrated into existing systems – for instance if switched motors are to be replaced by a modern controlled solution, which furthermore is excessively low-current. Another advantage results from the great speed setting range of 1:24. It offers a maximum range to still actuate the units at comparatively low speeds without an additional separate fan.
