Horizontal geared motors operate on the principle of gear transmission. The electric motor provides high-speed, low-torque input power, which is reduced in speed by a multi-stage gear pair (such as cylindrical gears, bevel gears, or planetary gears) within the reducer, thereby increasing the output torque. The reduction ratio is determined by the gear tooth ratio, with common reduction ratios ranging from 5:1 to over 100:1, selectable according to actual needs.
For example, when the electric motor operates at 1500 rpm, a reducer with a reduction ratio of 10:1 reduces the output speed to 150 rpm, while simultaneously increasing the output torque by approximately 10 times (ignoring efficiency losses). This characteristic makes horizontal geared motors suitable for applications requiring low-speed, high-torque drive.
