But when you get to the motion portion of the design, there are several technologies to consider, primarily [Brushless DC](https://www.portescap.com/products/brushless-dc-motor/ultra-ec-brushless-dc-motors), Coreless DC and [Stepper](https://www.portescap.com/products/can-stack-linear-actuators). 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.   [Read More](https://blog.portescap.com/selecting-the-optimum-motion-technology-for-your-application) Topics: [Others](https://blog.portescap.com/topic/others), [Motor Application Tips](https://blog.portescap.com/topic/motor-application-tips), [Quality](https://blog.portescap.com/topic/quality) ## [Learn More - Ultra EC Brushless DC Motors - Videos](https://blog.portescap.com/click-play-and-learn-more-about-portescaps-ultra-ec-motors) Posted by [Dave Beckstoffer](https://blog.portescap.com/author/dave-beckstoffer)   Jan 14, 2019 Portescap invites you to learn about the Ultra EC Brushless DC motors, which contain three optimizations to meet all application requirements.

The more powerful the motor in a smaller envelope, the higher the power density. Volume power density is an important consideration where space is constrained or where maximum output is needed in a fixed space. High power density enables miniaturization of applications and end devices or higher capability in current devices.
