LS ELECTRIC, INDUSTRIAL INNOVATION: FOCUS ON PLANETARY GEARBOX
The future of smart energy, LS ELECTRIC
LS Electric is a Korean company founded in 1974, so this year it celebrates its first 50 years in business; it currently has 3,500 employees and branches scattered around the world, and a mission: to create innovation in the world and bring about change at all times..
Ls Electric will be present in the coming days, May 28-30, 2024, at the SPS Italy 2024 in Parma: the trade show dedicated to the latest trends and innovations in industrial automation.

LS Electric, as a leading company in the industry, offers a complete range for factory automation, from PLCs – Programmable Logic Controllers – to servomotors and gearboxes of all types and for a wide variety of industrial applications . LS Electric is committed to providing all-round solutions in the factory automation market by offering a wide range of products with high performance and quality, including motion controllers, servo drives, and motors.
Today we focus on precision planetary gearboxes.
Ls Electric planetary gearbox, the best solution in the industrial automation market.
Planetary gearboxes are gear -driven speed reduction devices that are particularly useful when the following requirements are placed on an automation: high reduction ratios, high transmission torques and a good degree of load bearing capacity. Sometimes they can be coupled with electric motors for specific requirements. The LS ELECTRIC planetary gear reducer is a device that transfers more torque to the application, going to lower motor speed.
Epicycloidal gearboxes: operation
A planetary gearbox – also called planetary gearbox – is characterized by a single input and output shaft–coaxial–and a 3-type gear mechanism.
- Satellite gears – or planet gears-they connect the sun gear to the crown gear
- Gear solar – or solar pinion – from which rotary motion – incoming motion – starts, and which is connected to 3 or more other satellite gears
- Crown-the outermost gear connected to the satellites
The advantages of planetary gearing
Why are planetary gearboxes used? Planetary gearboxes offer many application advantages in various industries.They are also used as a viable alternative to parallel gearboxes.
- High reduction ratios: pbetter performance with lower cost and size
- Supporting higher loads
- High torques to transmit
Planetary gearboxes have input and output shafts aligned coaxially-this type of assembly results in greater compactness. Planetary gearboxes manage to transmit high torque in a simple and compact design, with high torque density and low backlash, adequate stiffness and low noise. Due to better load distribution, they have longer service life and allow large speed reductions through high gear ratios.
In our Online Shop there are mainly two types of planetary gearboxes:
Straight and Angular. Below we can see technical drawings provided by LS Electric outlining their differences and structure.
