Hybrid Drive
AMS developed the Enclosed Belt Drive (EBD) unit to fill a gap between the Flat Plate and E-Gear. Where the E-Gear utilizes gear reductions for both the first and second stage, the EBD keeps it simpler and lighter weight by using a belt-driven first reduction stage. This helps keep the cost of the unit down a bit and gives the user more control over speed. The drive pulley size can be decreased for more speed like the Flat Plate (not without sacrificing lifting capability however) but unlike the Flat Plate, the EBD requires no regular maintenance to the gearing.
