Gear motors are compact and suitable for high-load capacities. They have a high starting torque and are most often used for low-speed rotation. Hydraulic motors use a hydraulic power source to create mechanical energy to run winches, conveyors, balers, process equipment, mixer and agitator drives, and other industrial, agricultural, and process equipment. Gear motors, sometimes called low-speed, high-torque (LSHT) motors, have fixed displacement to provide constant torque and output motion. This listing is for each.
