PMDC and LRPX Gearmotors

The LRPX series BLDC gearmotors (Brushless DC) are efficient, compact, and specially integrated with a planetary gearbox. Due to its peak operational efficiency at low rpm, the LPRX series operates quietly, boasts a low power consumption and offers high torque.

The PMDC series (Permanent Magnet DC) of brushed gearmotors offer smooth control down to zero speed and continuous operation throughout an 8:1 speed range making them suitable for a wide range of industrial applications.
