General DPN

DPN WEB EXCLUSIVE: Bison Gear & Engineering Corp. has introduced a series of parallel shaft ac TEFC gearmotors. Available in 5 gear ratios ranging from 5.8:1 to 42.8:1, the 880 series gearmotors produce up to 1060 in. lb of continuous duty torque.

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. Each of the motors feature: permanently lubricated
shielded bearings that have been preloaded to reduce endplay, and a
dynamically balanced rotor shaft. In addition the three-phase motor
utilizes a class F UL recognized insulation system designed to meet
NEMA MG1 Section 31 standards and protect against voltage spikes. Both
motors bear the UL, CE, and cUL marks. The 880 series two and three
stage integral gear cases feature: precision (AGMA grade 9) hobbed
gears that have been induction heat-treated.
