An Essential Guide To Selecting Gearmotors

May 12, 2022

When it comes to industrial applications, gear motors remain one of the most used devices. Essentially a combination of an electric motor and a gearbox, gearmotors are primarily used to alter speed and torque. While it is excellent for torque multiplication and speed reduction, these devices are quite variable in terms of application and design. Thus, it’s fundamental to select the right one for a particular project. To execute that, here are 4 steps that you can undertake to make the best selection for your specific application.

4 steps to selecting a gearmotor.

Collect All Essential Technical Requirements

To select the right gearmotors, it is first essential to collect technical requirements such as torque, speed, rotations per minute (RPM) and power. A gearmotor’s speed and torque matter in particular because they will affect the overall system’s performance. For example, if the gearmotor has low speed, then it will not be able to produce a high torque, which may not be sufficient for some applications, as a high-speed gearmotor is needed for applications that require a high-speed output.


Determine The Number of Gearmotors

The number of gearmotors will also vary depending on the application. For example, a robot might use one gearmotor for each of the four wheels. Alternatively, designers can use motors connected to a drive shaft that runs through all four wheels and is driven by an encoder or potentiometer. Thus, ensure that you know how many devices you might need to run a smooth operation.


Choose Between Pre-assembled And  DIY Assembly Motors

Pre-assembled gearmotors are a set of gears, shafts, bearings and sometimes a motor that is ready to be installed in a project. These are the most popular choice for many projects because they are easy to install. Plus, pre-assembly saves time as it bypasses the assembly process.


On the other hand, when gearboxes are assembled in-house, teams can customize the gear ratios and configurations to exactly match the system’s needs. Thus, it offers better efficiency for your gearmotor, although it might take longer to assemble and operate. 


Perform Test Runs

Lastly, after addressing all the above points and purchasing your gearmotors, it is now time to test them. A new gearmotor could cause issues with other components in the system if it does not operate properly after installation. Hence, a test run is important so that you can identify and address these potential issues before they cause problems during everyday operations.


Thus, by following this guide, you can secure the right gearmotor for your application.
