Working Principle of Worm Gearmotor
Worm Gearmotor operates on the principle of a worm and a worm gear. The worm is a gear with a screw-like thread, while the worm gear is a gear with a cylindrical shape. When the worm rotates, it moves the worm gear. As the worm rotates, the worm gear moves in a circular motion.

Worm Gear Reducer Selection
We offer a wide range of Worm Gear Reducers to suit different requirements. The selection of the right Worm Gear Reducer depends on various factors such as the input speed, output speed, torque, and power requirements. Please see the table below for specific details.
| Model | Ratio | Input Speed | Output Torque | Power |
|---|---|---|---|---|
| WR 040 | 5:1 | 1440 rpm | 50 Nm | 0.25 kW |
