New parallel-shaft ac gearmotor

Paul Boughton

A new parallel-shaft ac gearmotor is the latest addition to the expanding Von Weise Drop-In Replacement gearmotor line from Bison Gear & Engineering Corporation. Available in eight standard models, the new VWDIR20 AC gearmotors feature 1/4 horsepower (186W) 115V, 60Hz split-phase electric motors.

The compact, integral gear reducers benefit from a phenolic high-speed gear for low noise and steel gearing in subsequent stages, with ratios ranging from 14:1 to 286:1. Corresponding fixed output speeds are from 120-6rpm, with continuous torque ratings from 11.3-67.8Nm (100-600inlb). The gearmotors feature built-in mountings, with overhung load (OHL) capability up to 136.4kg (300lbs).

Andy Petak, Bison Gear regional sales manager, comments: "This is the eleventh new Von Weise Drop-In Replacement Gearmotor we have introduced in the past 120 days and, based on demand, there will likely be more. We now have over 75 standard VWDIR models that can be referenced with CAD drawings at our website and all of them are available from Bison's distribution partners."

The new VWDIR20 AC parallel shaft gearmotors are designed for high-torque, single-phase commercial and industrial applications such as electromechanical pool covers and bleachers, compactors, can crushers, conveyors, commercial garage door operators and a wide variety of poultry and other agricultural equipment.

UL and CSA recognition are standard and CE recognition can be provided for OEMs. Bison Gear's Innopreneurial application and design engineering capabilities to customise standard models to meet specific OEM needs are readily available. All of the VWDIR gearmotors are manufactured in Bison Gear's suburban Chicago facility to Bison's high quality standards in order to ensure a short supply chain and reliable, long-life operation.

Bison's VWDIR line now includes right-angle, parallel-shaft and offset parallel-shaft designs utilising ac, dc and universal motors from 1/30 to 1/2 horsepower (25-373W), with fixed output speeds from 1.5-181rpm and continuous torque ratings up to 90.4Nm (800inlb).
