SEW-Eurodrive has added two- and six-pole versions to its established four-pole DR motor series.
According to the company, the new versions will mean motor applications can be matched to the most correct gear ratio.
Two-pole motors are ideal for high-speed applications, such as fans or pumps, while six-pole units have a slower-operating speed and can be used instead of multi-stage units.
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.
The new two- and six-pole options are available in high efficiency IE2-class DRE and premium efficiency IE3-class DRP motor variants.
The manufacturer says these variants are designed to exceed the efficiency requirements of the International Motor Efficiency Standard IEC60034-30 and the current Australian Standard AS1359.5.
The units are available with a choice of up to three different brake sizes per motor size and various inverter options.
The motors have an in-built encoder, but various incremental and absolute encoders can be added.
