Bison's parallel shaft gearmotors deliver more torque and power

Engineers designing equipment requiring heavy-duty torque and power from a standard 115 volt wall outlet faced a frustrating challenge. Few, if any, standard single-phase AC gearmotors offered as much as 800 in-lbs of continuous torque output. To fulfill that requirement, Bison Gear & Engineering Corp. introduces its one-half horsepower (373 watt) VWDIR40 gearmotors in three standard, off-the-shelf models. With gear ratios of 19:1, 28:1 and 56:1, they offer corresponding output speeds of 92, 62 and 31 rpm, and continuous torque ratings of 287, 400 and 800 in-lbs (32.4, 45.2 and 90.4 N-m), respectively. These Bison drop-in replacements for VW40 gearmotors feature split-phase, open drip-proof AC motors and integral gear reducers with all-position foot-mounting and grease lubrication for long life. 
Bison's VWDIR40 parallel shaft AC gearmotors are available with UL and CSA recognition and are supported by Bison's Innopreneurial application and design engineering capabilities to customize standard models to meet specific OEM needs.
The VWDIR40 AC gearmotors are the latest addition to Bison Gear's line of Von Weise drop-in replacement gearmotors, which is now made up of more than 80 standard models of AC and DC parallel-shaft and right-angle gearmotors.
