Product ReleaseNew Shaded Pole Gearmotors Available With Fail-Safe Disc Brakes
 American-made, parallel shaft AC gearmotors available in either open or closed fan-cooled design, with full-load torque from 42 to 113 in-lbs. Many OEM applications require the use of a fail-safe brake, which operates on the power-"off", brake-"on" principal. To fulfill that requirement, the new fractional horsepower parallel shaft VWDIR08 and VWDIR88 gearmotors from Bison Gear & Engineering Corp. represent a safe, long life, value solution with their dependable, unidirectional shaded pole motors. Designed as Von Weise Drop-In Replacements, the Bison VWDIR08 and VWDIR88 gearmotors are available in 14 standard models. With gear ratios from 27:1 to 750:1, fixed output speeds range from 2 to 60 RPM, with output torques from 42 to 113 in-lbs. These Bison drop-in replacements for VW08 and VW88 gearmotors feature UL and CSA recognized 1/10 and 1/20 hp shaded pole motors with clockwise rotation and 115 Volt, 60 Hertz input as standard. The gearmotors are grease lubricated for long life and all-position face or foot mounting with a 150 lb. overhung load rating. In addition, the shaded pole electric motors can be speed controlled with a simple, inexpensive triac drive. "With either open or enclosed fan-cooled construction and foot or face mounting, this is a versatile, excellent value gearmotor design that fits perfectly into such applications as conveyors, automated displays, rotisseries and other restaurant and foodservice equipment," said John Burch, Bison Gear Regional Sales Manager. "By design, shaded pole motors offer the fail-safe feature of starting in only one direction. That feature is further enhanced by the optional fail-safe brake available on the open motor designs. The shaded pole AC motor's running efficiency will increase with load, while also offering relatively constant speed with variations in load. These motors have no internal switches or brushes and are, therefore, ideal for continuous duty application." Manufactured in Bison Gear's St. Charles, Illinois facilities to the highest quality standards to ensure dependable, long-life operation, Bison's new VWDIR08 and VWDIR88 gearmotors are supported by Bison's Innopreneurial(TM) application and design engineering capabilities to customize standard models to meet specific OEM needs. The VWDIR08 and VWDIR88 AC gearmotors are part of the expanding Bison Gear line of Von Weise Drop-In Replacement gearmotors, which encompasses over 75 standard models. |

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.)
