Product ReleaseNew Bison Gearmotors Offer More Torque, More Power, and Backward Compatibility
Parallel shaft gearmotors powered by 1/2 HP (373 W), single-phase AC electric motors deliver 800 in-lb (90.2 N-m) continuous torque Until now, 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 continuous torque output. To fulfill that requirement, Bison Gear & Engineering Corp. introduces its new one-half horsepower (373 watt) VWDIR40 gearmotors in 3 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. "For their size, these are high torque, single-phase AC gearmotors with a rugged 400 pound (182 kg.) overhung load capability. That makes them ideal in such high torque applications as electromechanical pool covers and bleachers, compactors, can crushers, conveyors, commercial garage door operators and a wide variety of poultry and other agricultural equipment" said Gary Dorough, Bison Gear Regional Sales Manager. "The torque and power capability of this package are also greater than what most competitors offer in a comparable size gearmotor." Bison's new VWDIR40 parallel shaft AC gearmotors are available with U.L. and CSA recognition and are supported by Bison's Innopreneurial(TM) application and design engineering capabilities to customize standard models to meet specific OEM needs. Customers' shortened supply chain requirements are fulfilled by the units being manufactured in Bison Gear's St. Charles, Illinois facilities to the highest quality standards to ensure dependable, long-life operation. The VWDIR40 AC gearmotors are the latest addition to Bison Gear's rapdily expanding 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.  |

Bison Gear and Engineering has added their own drives to the already vast product line currently being offered to their customers. The drive product will consist or SCR (silicon controlled rectifier), PWM (pulse width modulated), SCR regenerative, and AC variable frequency drives. Now Bison offers a complete solution which includes the motor and drive from a single source, backed by industry leading engineers, outstanding customer service and the indoctrination of lean manufacturing practices. Bison is a family-owned business that has been supplying gearmotors, reducers and motors for use in heavy-duty commercial products for more than 45 years. Bison standard gearmotors are available up to 3hp/2.2kw, in both U.S. and European Union frequencies and voltages.
Available from stock, Bison's new 12 Volt DC parallel shaft products are available in horsepower ranging from 1/20 Hp to 1/6 Hp.
The new motors are mounted on our most popular gearcases, the Bison 100 and 300 Series. The 100 Series offers a wide speed range and many voltage options in an ultra-compact package. Torque ratings are up to 100 in-lbs continuous. For up to 300 in-lbs our 300 Series is unmatched in voltage and speed options.
Bison motors and gearmotors are available throughout the US and Canada.
There’s a simple philosophy behind the design of every Bison product: start with the highest quality components and then, through better design and manufacturing techniques, maximize the throughput those components can produce. Higher quality components means more dependable performance, fewer field failures, up to 200% more torque than typical - leading to a lower cost per inchpound of torque, a more compact product, and longer service life.
1) Housing – Single Piece aluminum housing – Lighter and dimensionally stronger than zinc, our gearcase is machined on automated mills for superior alignment of bearings and gearing.
2) Finned End Bell –Bison’s finned rear end bell not only reduces weight, but more importantly improves the thermal resistance of the frame.
Using the same high quality components that have set the industry standards for over forty years, Bison is proud to introduce our 562 series hollow shaft gearmotor. Robusticity… Increased low speed center distance, coupled with greater clearance for wider faced gears, the 562 allows users to obtain close to twice the continuous torque ratings! (1100 in-lbs. continuous vs. competitor’s 600 in-lbs.)
