Demonstrating corresponding fixed output speeds from 120 to 6 rpm, Bison Gear & Engineering’s VWDIR20 parallel shaft AC gearmotors demonstrate a continuous torque rating from 100 in./lb to 600 in./lb (11.3 N/m to 68.8 N/m). The devices utilize ¼-hp (186-W) 115-V, 60-Hz split-phase electric motors, and act as Von Weise drop-in replacements. The units have integral gear reducers with a phenolic high-speed gear for steel gearing in subsequent stages with ratios ranging from 14:1 to 286:1. The instruments offer foot or face mounting with overhung load (OHL) capability up to 300 lbs (136.4 kg). The products perform in single-phase commercial and industrial applications, such as electromechanical pool covers and bleachers, compactors, can crushers, conveyors, commercial garage door operators, and poultry and other agricultural equipment.
