A 15hp gear motor is an electric motor with a 15 horsepower (HP) power rating, combined with a gearbox. This unit provides both high power output (15 HP) and torque multiplication, making it suitable for heavy-duty industrial applications like pumps, compressors, and conveyors. The motor itself can run at speeds up to 2930 RPM or more, while the gear reducer lowers the output speed and increases torque.
