BMG’s new Nord DuoDrive unit – an integrated geared unit that combines the recently launched Nord IE5+ synchronous motor and a single-stage helical gear unit in one compact housing – has been designed for optimum system efficiency.
That’s according to Deon Crous, National Product Specialist, Nord Drive Systems, Electromechanical Drives division, BMG, who said that by installing the motor and the gear unit in a single housing, the lightweight DuoDrive offers many benefits, including high power density, low noise emissions and reduced installation space.
“With the launch of this new integrated system, Nord Drive systems is setting new energy efficiency standards of drive systems in food and pharmaceutical production, as well as the intralogistics sector.”
Crous said other benefits of the new DuoDrive are fewer wearing parts, which reduces maintenance requirements and the simple commissioning of a complete solution via plug-and-play, decreases the Total Cost of Ownership (TCO) compared to existing drive systems.
“This corrosion resistant unit has an advanced wash-down design and is suitable for safe use in hygiene-sensitive and harsh environments. Because this unit is easy to wash, cleaning costs are reduced.”
He said the DuoDrive system currently offers the highest efficiency of a gear unit/motor combination in this power class and achieves high system efficiency in the partial load range. This is an advancement on Nord’s LogiDrive concept, where the IE5+ synchronous motor is combined with a NordBLOC.1 bevel gear unit.
DuoDrive units available from BMG cover gear unit speed ratios of i = 3.24 to i = 16.2 and are designed for torque ranges of up to 80 Nm and speeds of up to 1,000 min-1.
As with all products in the Nord portfolio, DuoDrive is compatible with Nord drive electronics and can be equipped with common hollow shaft dimensions (20 to 40 mm) and flange versions (B5 and B14) or a torque arm. Depending on specific requirements, Harting HAN connectors, M12 round plug connectors or direct wiring are provided for the motor connection. Other options include an encoder feedback or holding brakes.
