Lenze type MCS synchronous servo motors have been chosen by German automatic handling specialists Beewen for customised telescopic conveyors in their storage and retrieval systems. These double belt conveyors are used to place and remove goods in automatic warehouses. They are positioned by stacker crane and their design is customised according to the goods being stored. The small size and high performance of the Lenze MCS servo motors allows flexibility to meet customer requirements.
The telescopic conveyors are fitted with MCS motors up to 4kW in power. The controllers are Lenze 9300 servo drives mounted on-board of the stacker crane. After careful analysis of the operating conditions taking into account the intensity of usage and the desired maintenance-free lifetime, Beewen standardised on the MCS range. Motors deliver up to three times nominal torque with virtually zero cogging effects and energy efficiency far above that of asynchronous motors. Direct mounting to helical, bevel and planetary gearboxes aids the mounting flexibility. This is further enhanced by compact dimensions such that 4kW nominal power can easily be delivered with a motor body section of only 110 x 110mm.
