Transmit rotation between the perpendicular shaft (not intersecting, there is an offset between them). The worm resembles a screw which can be right handed or left handed. Worm gear sets usually used when high reduction in speed is desired. It transmits rotation from the worm to the worm gear, but not the opposite. Range from 20 Watt to 3 HP.
A Worm Gear PMDC Motor is a permanent magnet DC (PMDC) motor combined with a worm gearbox, featuring a screw-like worm that meshes with a spur or helical gear to provide high torque and speed reduction between perpendicular, non-intersecting shafts. These motors offer high efficiency, low noise, and high radial load capacity, with common applications in material handling, packaging equipment, and industrial machinery due to their ability to produce high output torque at low speeds and their self-locking ability.

PMDC Motor:
This motor uses permanent magnets in the stator to create the magnetic field, replacing stator windings.
-
Worm Gearbox:
This component consists of a screw-like worm that drives a mating spur or helical worm gear. The worm is typically a right or left-handed screw.
- The worm, driven by the PMDC motor, rotates.
- The worm meshes with the worm gear, transmitting rotation.
- The worm gear is designed to provide a significant reduction in speed and a substantial increase in torque at the output shaft.
- High Reduction Ratios: Worm gearboxes excel at achieving high reductions in speed.
- High Torque: They are ideal for applications requiring high output torque.
- Self-Locking: In many cases, worm gears are self-locking, meaning the gearbox will not turn backward from the output side, providing mechanical braking.
- Compact Design: Worm gearboxes offer a compact solution for high reduction ratios.
- Low Audible Noise: They are known for their low noise operation.
- High Radial Load Capacity: These motors can withstand high radial loads.
