All you need to know about gear motors and their components

What is a gear motor ?

Gear motors are mechanisms that adjust the speed of electric motors, allowing them to operate at a certain speed. They are made up of a series of gears that form a kinematic chain, working on a set of rotary parts.

Their main objective is to allow the initial high speed to decrease without negatively affecting the mechanism. In addition to this adjustment, a gear motor is in charge to adjust the mechanical strength of a system.

Types of speed reducers and gear motors

If we focus on their intrinsic nature, we can classify motor speed reducers as follows:

Planetary speed reducers

Planetary gear motors are arranged in stages, each with the following structure:

• Sun, central gear. It revolves around the central shaft of the system
• Carrier, which carries up to 3 gears and meshes with the sun
• Ring gear attached to satellites

The central shaft can also be used as a center of rotation, making it easy to switch directions.

This type of gear motor is highly reliable. It is for this reason that it is used in many automated transmissions. Also, it is quite versatile, making it ideal for many fields - from industrial automation to robotics..

Among the advantages of planetary gear motors we can find:

• Their great angular rotational stability and, therefore, their high degree of precision.
• Their limited vibration when handling different loads
• Their uniform transmission capacity allows more repetition

It should also be noted that these motor speed reducers have a high contact surface. This means that they engage more easily and generate lower noise levels.
