Dunkermotor's Gearmotor Solution is More Energy Efficient than Electric Motors

To meet the needs of OEMs requiring a high torque, low output speed non-backdrivable gearmotor without sacrificing energy efficiency, Dunkermotor, now part of AMETEK Precision Motion Control, has 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 new Dunkermotor 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 WormetaryTM 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 WormetaryTM configuration can be applied to Dunkermotor's long-life brushed permanent magnet DC (PMDC) motors in frame sizes from 42 to 80 mm.

"We believe that for many OEMs the WormetaryTM gearmotors offer a better value solution than bevel or hypoid gearing where energy efficiency is important and their application requires a non-backdrivable gearmotor," said Wilfrid Vinson, president of Dunkermotoren USA, Inc. "This is just one more example of the many types of solutions which are made possible by the modular Dunkermotor system of engineered components made up of brush and brushless DC motors up 530 Watts (0.71 hp), our planetary and worm gearboxes, encoders, and brakes, as well as a family of integral controls and fieldbus interfaces."

WormetaryTM gearmotors in the 53 and 63 mm sizes can be provided with integral 4-quadrant speed controllers as well as IP 65 environmental protection.

To meet the international sales requirements of its customers, Dunkermotor's brushed DC motors employed in the WormetaryTM 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.
