SEW-Eurodrive DR series two- and six-pole motors

SEW-Eurodrive has extended its DR motor series with the inclusion of two- and six-pole variants. The addition of two- and six-pole DR motor options enables more precise matching of gear ratios to a wider range of end-user applications.

Two-pole motors are suitable for high-speed applications, such as fans or pumps, while the slower operating speed of six-pole motors can be leveraged to circumvent the need for a multistage gear-unit. This minimises the size of the gearmotor assembly and reduces the cost to the end user.

The two-pole motor option is offered in outputs ranging from 0.25 to 9.2 kW, and the six-pole motor is available from 0.18 to 5.5 kW. They are available in IE2-class DRE (high efficiency) and IE3-class DRP (premium efficiency) motor variants within the DR family. These are designed to exceed the efficiency requirements of current international and Australian standards.

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. Various incremental and absolute encoders are available, as well as a built-in encoder. SEW-Eurodrive also offers more compact copper-rotor variants of the DRE and DRP induction motors in addition to the traditional aluminium-rotor motors.
