DC Worm Gear Motor is a kind of motor widely applied in daily life. For example, the range hood in the kitchen is a typical application.

Dc Worm Gear Motor has the following characteristics:
1. Achieve great speed reduction through high gear ratio. Normally reduce the speed as low as 10 rpm.

2. Achieve vertical transform by the worm gear

3. With self-lock function to prevent the back-driving.

However, no matter 3v DC Worm Gear Motor or 6V Dc Worm Gear Motor, the disadvantage is low efficiency, that is about 40%

58mm DC Worm Gear Motor mainly includes 58W31ZY

58mm dc worm gear motor

According to the number of stages, 58Mm Dc Worm Gear Motor has following types:

For 3 stages worm gearbox, we have 49, 74, 101, 218, 290 gear ratios;

For 4 stages worm gearbox, we have 505, 634 gear ratios
