Product ReleaseBison Gear Debuts Pair of Parallel Shaft Von Weise Drop-In Replacement Gearmotors Print
 Responding to the shortened supply chain needs of a broad range of established OEMs, Bison Gear & Engineering Corp. introduces its new VWDIR84 parallel shaft, fractional horsepower gearmotors designed as Von Weise Drop-In Replacements. The Bison VWDIR84 is available in 13 standard models, with output speeds from 6 to 85 RPM and torques from 50 to 600 in-lbs. Three models are powered by a dual voltage (115/230V), dual frequency (60/50Hz) permanent split capacitor 1/12 hp AC motor. Ten standard DC models are available driven by either 12V or 90V permanent magnet DC motors. The Bison drop-in replacements for VW84 gearmotors feature standard 0.75 inch output shaft diameter and built-in foot mounts. "This is a proven design with a reasonably high overhung load capability of 250 pounds that makes it ideal in applications like foodservice, agricultural, and woodworking equipment, as well as electrical switchgear, conveyors and automated file systems," said Andy Petak, Bison Gear Regional Sales Manager. "The gearmotors are reversible and their grease lubrication allows mounting with the output shaft up, down or horizontal." Manufactured in Bison's U.S.A. facilities to the highest quality standards to ensure dependable, long-life operation, Bison's new VWDIR84 gearmotors are available with U.L. and CSA recognition and are supported by Bison's solid application and design engineering support to customize standard models to meet specific OEM needs.

By: John Morehead, Bison Gear & Engineering, St. Charles, IL The focus should be placed on improving and replacing more-ubiquitous fractional horsepower devices. With the concerns over the growing energy crisis, the efficiency of electric motors has become an important, timely topic. The reason: electric motors consume from 63% to 70% of the electricity used in domestic manufacturing, and represent 23% of the total electricity consumption in the U.S. However, most motor efficiency efforts to date have focused on only about 10% of the total electric motor population. A unique opportunity exists for OEM machinery designers to contribute to energy conservation efforts by carefully selecting and applying appropriate new electric motors, gearmotors, and drives. Legislating efficiency The 1992 Energy Policy Act (EPAct) and the Energy Independence and Security Act of 2007 (EISA ) have done a lot to legislate new levels of increased motor efficiency. For good reason, these efforts have been primarily directed at integral (greater than one) horsepower electric motors. ...More >> AC Parallel Shaft Gearmotor is Bison Gear's Latest Von Weise Drop-In Replacement
