Functioning on the power-“off” brake-“on” principle, Bison Gear & Engineering’s VWDIR08 and VWDIR88 fractional horsepower parallel shaft AC gearmotors work with fail-safe disc brakes. The instruments include gear ratios from 27:1 to 750:1, fixed output speeds from 2 rpm to 60 rpm, and output torques from 42 in./lbs. to 113 in./lbs. The motors offer UL- and CSA-recognized 1/10 and 1/20 hp shaded pole motors with clockwise rotation, 115 V 60 Hz standard input, and speed control via a triac drive. The open or closed fan-cooled designed devices are grease lubricated, and have all-position face or foot mounting with a 150 lbs. overhung load rating.
