New integrated unit ensures high system efficiency

Industrial products provider 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.

“By installing the motor and the gear unit in one single housing, the lightweight DuoDrive offers many benefits, including high power density, low noise emissions and reduced installation space,” says BMG NORD drive systems national product specialist Deon Crous.

He adds that with the launch of this new integrated system, NORD DRIVESYSTEMS is setting new drive systems energy efficiency standards in food and pharmaceuticals production as well as the intralogistics sector.

“Other important benefits of BMG’s new DuoDrive unit is that there 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 compared to existing drive systems, highlights Crous.

This corrosion resistant unit has an advanced wash-down design and is suitable for safe use in hygiene-sensitive and harsh environments. Owing to this unit being easy to wash, cleaning costs are reduced.

The DuoDrive unit 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 80Nm 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 mm to 40mm) 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.

NORD DRIVESYSTEMS, developed by the manufacturers of drive technology – for mechanical and electronic solutions Getriebebau Nord and assembled locally by BMG, comprise optimum drive configurations to ensure high-performance of mechanical speed control for specific applications in almost every industry.
