As a design engineer, there is always excitement when you get to work on new product development. But when you get to the motion portion of the design, there are several technologies to consider, primarily Brushless DC, Coreless DC and Stepper. Which technology is best and where do you start? The challenge can be difficult as there are several factors to consider including output speed, torque, lifetime, mechanical envelope, noise, weight, cost and precision. It is not practical to analyze, purchase and test multiple technologies as this would be expensive and time consuming. Fortunately, there are guidelines that can assist in the initial review of the different technologies to narrow the selection.
Throughout the other posts in this series, we will look at the different factors and detail the guidelines to use for each. This will develop a Motor Decision Tree that will help you determine the best technology or technologies to consider for your application so you can shorter your initial design time.
