The new parallel shaft AC gearmotors from Bison Gear & Engineering are available in five gear ratios ranging from 5.8:1 to 42.8:1. The 180 Series gearmotors can produce up to 1,060 in.-lbs. of continuous torque. According to the company’s press release, two 1-1/2 hp motor options provide the specifier with the option of a single phase 115/230 VAC 50/60 Hz motor or a three-phase 230/460 VAC 50/60 Hz motor for greater efficiencies and heavy duty inverter applications. Motors are totally enclosed and fan-cooled, therby protected from common hazards. Special motor features include permanently lubricated shielded bearigns that have been preloaded to reduce endplay and a dynamically balanced motor shaft for smooth operation. The 880 series of two- and three-stage integral gear cases features precision hobbed gears that have been induction heated, a helical high speed mesh that is skive hobbed for minimum gear noise, and oil bath lubrication in the permanently sealed gear cases.
