Gearmotors Types and Industrial Applications

Friday - 27/11/2020 09:54
A geared motor is an all-in-one combination consisting of an electric motor and a gearbox. Used for high torque and low speed applications, it is a particularly simple and cost-effective solution to achieve optimal energy efficiency.
Gearmotors Types and Industrial Applications
The gearbox allows to increase torque while reducing the speed of the prime mover output shafts. In other words, it works like a speed and torque converter. Specifically, it uses the mechanical advantage by transmitting motion from the input shaft to the output one.

Common types of gearmotors

There are different classifications of gearmotors. The first is made according to the power of the gearbox and distinguishes three main models: parallel shaft gearboxes, angular gearboxes, and planetary gearboxes. However, it also depends on the type of motor, with the main distinction being between AC or DC motor. In fact, gearmotors can use AC (alternating current) or DC (direct current) power, even if today the most common ones have a three-phase asynchronous motor or a permanent magnet synchronous servomotor. This distinction can affect various performance factors, including reliability, speed control complexity, and cost.

Industrial applications for gearmotors

Gearmotors are generally used in applications that require a high output torque and a lower output shaft rotation speed. Furthermore, they are a particularly ideal solution where space and power are limited thanks to their compact design and modularity. Among the possible applications of gearmotors we find many systems and machinery in different sectors, industrial and not. Some examples:

    Transport and logistics systems
    Automotive, throughout the production process
    Food & beverage, from packaging to filling
    Robots and handling machines

How to select the right gearmotor

    Review the application requirements for the gear motor, namely:

    General requirements, from mounting orientation to dimensions.
    Input power source: voltage, frequency, maximum current, etc.
    Gear motor specifications: dimensions, weight, noise level, etc.
    Gear motor performance: speed, torque, power, etc.
    Operating environment: application and ambient temperature, degree of ingress protection.

    Select the correct motor based on the application requirements.
    Make sure that the gearmotor is sized correctly for the desired application based on the speed and torque requirements of the load to be operated.
    Perform the necessary tests to ensure proper engine operation in a typical operating environment.
