Selecting the Optimum Motion Technology for your Application Series: Accuracy

Posted by Dave Beckstoffer   Sep 06, 2019   0 Comments

Another factor to review is the accuracy required from the motion system in the application.  Is the motion continuous or incremental?  What is the resolution needed from the motor during incremental operation?  Does the motor need to have different resolutions for different points in the operation?

Selecting the Optimum Motion Technology for your Application Series: Mechanical Envelope

Posted by Dave Beckstoffer   Aug 21, 2019   0 Comments

The next factor for consideration is the mechanical envelope for the motion system.  What is the space in the product that is dedicated to the motion system?  Is there flexibility on the diameter or length?

Selecting the Optimum Motion Technology for your Application Series: Lifetime

Posted by Dave Beckstoffer   Jul 19, 2019   0 Comments

The next factor we will consider is the lifetime requirement of the motion system.  How many cycles must the motion system execute within the life of the product?  How many hours does that require from the motion system?

Selecting the Optimum Motion Technology for your Application Series: Torque

Posted by Dave Beckstoffer   Jun 28, 2019   0 Comments

The next factor we will consider is the output torque requirement of the motion system.  What is the continuous torque requirement during operation?  Is there a peak torque for a limited time that needs to be considered?  Is the safety margin enough to compensate for the other factors in the application?

Selecting the Optimum Motion Technology for your Application Series: Speed

Posted by Dave Beckstoffer   Jun 06, 2019   0 Comments

One of the first factors to consider in your new product development is the output speed requirement of the motion system.  How fast does the motor need to rotate to drive the mechanism in the application?  And are there various speeds that need to be accommodated?  There are some general guidelines that will help you narrow down the technologies to consider:

Selecting the Optimum Motion Technology for Your Application

Posted by Dave Beckstoffer   Feb 15, 2019   0 Comments

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.

Application Torque Range

Posted by Dave Beckstoffer   Dec 19, 2018   0 Comments

In our blog post DC Coreless Speed vs Torque Curves, we talked about how to read speed vs torque curves and the linear relationship of speed and torque for a DC motor.  When comparing speed vs torque curves for various motors, the range of torque required in the application should be identified to ensure a proper comparison.  The curves will show the torque capability of the motor over the entire speed range, but the application torque range is typically limited to a narrow band.

Power Density Increases Performance

Posted by Dave Beckstoffer   Nov 06, 2018   0 Comments

Power density is the amount of power (time rate of energy transfer) generated per unit volume of the motor. 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.
