Baginto AB, a Swedish bakery, has upgraded its mixing and dough-preparation equipment with SMV inverter drives from Lenze.

The IP65 rating of the SMV drives allows them to be mounted directly to the machine frame close to the motors.

The resulting variable-speed control has improved productivity and the quality of the baked products.

This recent investment means many areas of the bakery are now controlled by Lenze variable-speed drives.

Supplied as retrofits, the SMV inverters provide smooth torque operation and fine speed control in areas such as flow mixing and dough folding.

The SMV is a high-performance sensorless vector inverter with IP65 enclosure available from 0.37 to 7.5kW.

It suits either single- or three-phase supplies.

A simple keypad and a plug-in memory module that holds all the drive settings simplify handling.

An optional lockable isolator allows safe isolation of the drive.

Mounting the drive on a machine surface close to the motor removes the need for a new cabinet or for space in an existing cabinet.

In addition, the motor power cables are shorter and usually EMC regulations can be met without the need for shielded cables, saving installation time and purchase costs.

At Baginto, some machines are moved around as part of the production process.

The SMV drives stay with the machine and operators can use the keyboard to make manual adjustments during production.

Baginto uses two types of Lenze inverter – the SMV for machinery where there is no panel and the IP20 enclosed SMD where a panel is available.

Both operate in a similar way and effectively make a single drive solution for all the bakery requirements.

The inverters have allowed Baginto to increase productivity with minimal disruption.
