Encoders make motion control possible by sensing the motor’s speed and position and sending feedback signals to control components. Two square waves, or channels, shifted 90 electrical degrees from each other, along with an optional index pulse that occurs once per revolution, encode the angular position data.  [Read More](https://blog.portescap.com/how-encoders-provide-motor-speed-and-position-control) Topics: [Motor Application Tips](https://blog.portescap.com/topic/motor-application-tips), [Encoders](https://blog.portescap.com/topic/encoders), [motor performance](https://blog.portescap.com/topic/motor-performance) ## [Motor Selection Tips: Understanding Thermal Parameters of DC Motors](https://blog.portescap.com/understanding-thermal-parameters-of-dc-coreless-motors) Posted by [Manoj Pujari](https://blog.portescap.com/author/manoj-pujari-1)   Jul 08, 2021 Motor Selection Tips: Understanding Thermal Parameters of DC Coreless Motors *With the help of simple thermal modeling* When trying to understand the phenomenon of heating of coreless dc motors, its helpful to express it as a simple thermal model and to draw an analogy with an electrical system. Looking at Fig. 1, you can see the power dissipated (heat) is the difference between electrical input power and the mechanical power (speed & torque) generated by motor shaft. With this basic understanding , let’s next examine the thermal model of a [DC coreless motor](https://www.portescap.com/en/products/brush-dc-motors/brushed-dc-motor-basics).

While some simple surgical tools can be manufactured inexpensive enough to be economically thrown away after each use, more sophisticated tools such as drills, saws, and shavers must be reusable and therefore[sterilized](https://www.portescap.com/en/solutions/autoclave-sterilization). The motor is a critical part of these tools, and if not protected properly, its electronic components can be susceptible to the moisture and temperature of the steam sterilization process (autoclave).

Our AEs will gather valuable information during the motor selection process, to ensure that they use the right motor for the allotted space and application.  After a thorough analysis and discussion, they can provide speed/torque curves for various motor options. If they know the duty cycle, they can help to determine whether or not to use a smaller motor in a temporary overdrive application.

Often a product catalog only lists a selection of available motors and coils, so the ideal solution can't be found by browsing through available standard options. Some motor manufacturers offer customizations, which require time and money to be invested and might not always be an option depending on the size of the project.

A rotor, balanced or unbalanced, wants to revolve around its mass center axis. The balancing process brings these two axes together. As illustrated below, when the mass that causes the imbalance is removed, the two axes merge.   [Read More](https://blog.portescap.com/a-balancing-act) Topics: [Others](https://blog.portescap.com/topic/others), [Motor Application Tips](https://blog.portescap.com/topic/motor-application-tips) ## [Selecting the Optimum Motion Technology for Your Application](https://blog.portescap.com/selecting-the-optimum-motion-technology-for-your-application) Posted by [Dave Beckstoffer](https://blog.portescap.com/author/dave-beckstoffer)   Feb 15, 2019 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](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) ## [Application Torque Range](https://blog.portescap.com/application-torque-range) Posted by [Dave Beckstoffer](https://blog.portescap.com/author/dave-beckstoffer)   Dec 19, 2018 In our blog post[DC Coreless Speed vs Torque Curves](https://blog.portescap.com/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.
