4 Step Guide To Select A Geared Motor

The selection of the right geared motor sometimes resembles to the high school popularity contest – it is always easy to look at what others are using, thus assume that the same will work for you as well. But, maybe it is time to re-think this strategy, don’t you think so?


It is no secret that for design engineers, one of the most difficult components to source during the selection of the best components for a particular application, is the geared motor. What makes the selection even harder is the fact that today’s market is overflowed with a bevy of different promising models of geared motors that scream ‘unmatched quality’, ‘super-efficiency’ and ‘highest precision’.

When it comes to geared motors, there are few key design parameters to follow, so this is why we have prepared a simple 4-step guide to take you to the best geared-motor selection for a particular application.

  • Step No.1 – Determine The Application RequirementsAs a fist and extremely important ‘to-do-, the determination of the application requirements is often overlooked, which usually leads to making the wrong choice. For the entire selection process, a gathered design inputs information is crucial, as this is what will dictate the ideal motor for the specific application. It is recommended to create a checklist of the most important parameters and different requirements specific to your project.
  • Step No.2 – Select The Motor TypeThe next step is to find out the type of geared motor technology that will ideally match the intended application. The design inputs may be considered a selection matrix for the decision process. Each application features different (unique) characteristics, so it is very important to determine which parameters need to be considered for the application. Parameters such as: lifespan, horsepower, efficiency, noise ratings and starting torque.
  • Step No.3 – Select The Matching Speed And The Torque Output For The Geared MotorThere are two methods offered for successful accomplishment of this task:

    – Select the motor and the gearbox separately and assemble

    – Select a pre-engineered gearmotor

    However, the second option is preferred, as it reduces the design time and the project risk. In other words, the pre-engineered gearmotor solution ensures that the manufacturer has done a lot of heavy lifting to make sure that the motor and gearbox matching will work impeccably together.

  • Step No.4 – Ensure That The Application Yield Strength And Pull Up Torque Match The ApplicationThe last but not least step is to perform a couple of test runs in a sample environment in order to make sure that the installed geared motor works as supposed. If test results reflect in motor stress, unnatural noises or extreme motor heat, you should contact the manufacturer itself.
