In the 1990s and 2000s, bottle, crate, and pack transport almost exclusively used worm gear motors from various manufacturers that, from today’s perspective, have very poor efficiency. These drives are now increasingly subject to revision, repair due to wear. The costs for this are in part not inconsiderable, especially when it comes to the so-called Eco-drive from Krones (KRV063 and KRV080), a worm gear with belt transmission and three-phase motor. Here, the repair costs often exceed the new acquisition of a bevel gearbox with three-phase motor in IE3 or even IE4 design. Incidentally, this also applies to the transporter drives from SEW in the SA42/47 and SA52/57 design with old IE1 motors DT… and DV….
To this end, there are current bevel gear motors in compatible dimensions from various manufacturers, which have an amortization time of zero to a maximum of 1 year, assuming an operating time of about 5000 h/a, simply due to the improvement in efficiency. The advantage of these conventional drives compared to today’s modern drives with IE4 synchronous motors is that no or only minor changes need to be made to the control, because the old frequency converters can remain. Another advantage is that the old replaced drives could still be available as replacements.
We would be happy to provide you with a comparative quote for this with your preferred drive unit. Please enquire about your requirements, specifying the drive unit to be replaced, preferably with a well-readable photo of the nameplate of the gear unit and the motor, for Krones drives please also with the specification of the belt transmission.
