SEW-Eurodrive DR motor series

SEW-Eurodrive has extended its energy-efficient DR motor series with the inclusion of new 2- and 6-pole variants, complementing its established 4-pole DR motor varieties. Combined with many user options, the extended DR motor line-up provides enhanced motor choice and flexibility, delivering optimised energy efficiencies to a broad range of drive applications.

The addition of 2- and 6-pole DR motor options enables more precise matching of gear ratios to a wider range of end-user applications. 2-pole motors are suitable for high-speed applications, such as fans or pumps, while the slower-operating speed of 6-pole motors can be leveraged to circumvent the need for a multi-stage gear-unit. This both minimises the size of the gear-motor assembly and reduces the cost to the end user.

The 2-pole motor option is offered in outputs ranging from 0.25 to 9.2 kW and the 6-pole motor is available from 0.18 to 5.5 kW. The 2- and 6-pole options are available in IE2-class DRE (high-efficiency) and IE3-class DRP (premium-efficiency) motor variants within the DR family. These are all designed to exceed the efficiency requirements of IEC 60034-30 and the current AS1359.5.

The compact DR motors are available in a variety of form factors, including a choice of up to three different brake sizes per motor size and various onboard inverter options. Rated up to IP66, the DR series can be supplied with an extensive selection of features and mounting alternatives. Additional flexibility can be obtained via various incremental and absolute encoders and a built-in encoder.
