Bison Gear & Engineering 011-348-3216 DC Gear Motor

Bison Gear & Engineering DC Gear Motor 011-348-3216 (also listed as 32-999-2904-028) is a direct-current geared motor with a 216:1 reduction and a published output of 9 RPM at 90 VDC. DC gear motors combine a DC drive with a reduction gearbox to achieve slower output and increased torque at the shaft. The 216:1 gear ratio means the motor’s input shaft spins 216 times for each output shaft turn, producing low-speed, controlled rotation according to the data provided. The two part numbers reference the same unit across catalogs, aiding cross-reference and replacement. The provided specifications—90VDC input, 9 RPM output, and 216:1 gearing—define the essential operating parameters needed to verify compatibility with a drive system and load requiring a low-speed DC geared solution.
