How to size and select gearboxes: A Motion Engineer’s Guide
Updated May 2016. || Application-tailored and custom gearboxes are increasingly common, mainly because they’re easier than ever to manufacture to specification. That’s not to say that the design work isn’t challenging. However, modern manufacturing lets some suppliers make gearboxes and components to meet specific application requirements. New supplier approaches to giving engineering support as well […]
How to Select a Gearmotor in Four Simple Steps
Updated May 2015. || Consider key design parameters when selecting a gearmotor for a motion control application. Step One: As the motor or gearmotor selection process begins, first gather the relevant technical and commercial requirements. This first step is often overlooked, but it’s a critical component in the design process. The gathered information will then be used […]
How to Choose a Servo Motor
Correctly sizing motors in a motion control application is more difficult than sizing an AC induction motor because not only must acceleration, deceleration and running torque be taken into account, but also the ability of the servo motor to tightly control the load’s speed, position or torque. This means the peak torque measurements must be […]
How to size and select servo systems in eight easy steps
Updated July 2016 by Lisa Eitel || Servo systems provide amazing levels of speed, accuracy, and flexibility in automated equipment when the correct servo is chosen for the application. Unfortunately, choosing the wrong servo can lead to difficulty in tuning, poor accuracy, or underwhelming performance. With so many different servos to choose from, how do […]
How to select and specify stepper motors: A design engineer’s guide
Updated July 2018 || Stepper motors are a good choice for many motion control applications, if they’re selected properly. Here’s a quick review of some key tips for making the right choice. First, define the motion profile. This includes such parameters as required positioning time and acceleration/deceleration time. Related factors include the required positioning increments […]
How to size and select a dc motor: A motion engineer’s guide
There are many motor choices on the market today, from heavy-duty AC motors to tiny DC brushless and stepper motors. To select the right motor for the application, users must have a full understanding of the application parameters, including power, speed, torque, physical size, efficiency, lifetime expectations, and other requirements. There have literally been books […]
