Where the EPNMRV 025 Is Used
Typical installations include small-format packaging machines, laboratory sample conveyors, automated sliding gates, PCB handling systems, and compact rotary indexing tables. In Australia, we frequently supply the EPNMRV 025 to OEMs building benchtop automation equipment and precision dispensing systems for the pharmaceutical sector.
When to Choose This Model
Choose the EPNMRV 025 when your envelope constraint is the primary driver and the required output torque stays below 15 Nm at continuous duty. If your application demands higher torque or a wider motor flange, step up to the EPNMRV 030 (30 mm centre distance).
For detailed information on housing materials, worm gear efficiency characteristics, and installation orientation guidelines, refer to the EPNMRV Series overview.
