MOTION SYSTEM APPLICATIONS
Automotive, medical, robotic applications
benefit from dc motors
Among motors used in industrial and motion applications, dc motors are still some of the most common including brushed, permanent magnet, as well as brushless dc motors. Thanks to continuing improvements, dc motors have found their way into a wide range of applications. For instance, they’re common in automotive manufacturing, particularly as the number of motors used for various systems and subsystems in cars goes up – for everything from window and door controls to seat adjustment. Other areas have also been seeing increased usage of dc motors, particularly in medical applications. The fact that many of these applications are limited in space and need small motor designs to fit makes them particularly attractive. That, and that they offer a balance of power and torque in a compact package makes them well suited to uses in many medical applications, such as in surgical hand tools. Aside from their prevalence in automotive and medical applications, industrial applications involving robotics are using dc motors to solve the unique challenges of building the next generation of robots and collaborative robots, or cobots. Case in point: As collaborative robots have proliferated, the need for a wide variety of grippers and end effectors suited for a range of uses has also grown. One of the most challenging applications is for automated gauging and measurement of small parts. Here, end effectors must provide high-resolution positioning with resolutions as low as 2.5 micrometers. This information must also be continually available to decision-making software in many different automation applications.
