July 19, 2012 -- Dunkermotor paired a right angle worm gear to turn the corner with an efficient planetary gearbox for high reduction ratios as well as high torque capability. The Wormetary gearmotor configuration is 2.5 times more energy efficient at an overall 80:1 ratio than what can be achieved through worm gear reduction alone. The Wormetary gearmotors can be designed to be non-backdrivable or self-locking and are offered with overall gear reduction ratios ranging from 22.5:1 to 35,000:1, with peak torque capability up to 320 N-m (2,832 in-lbs).
The Wormetary configuration can be applied to Dunkermotor's long-life brushed permanent magnet DC (PMDC) motors in frame sizes from 42 to 80 mm. Wormetary gearmotors in the 53 and 63 mm sizes can be provided with integral 4-quadrant speed controllers as well as IP 65 environmental protection. Dunkermotor's brushed DC motors employed in the Wormetary gearmotors have received UL and cUL certifications for the U.S. and Canada as well as CE and CCC certifications for the European and Chinese markets.
