Welcome to this installment of MC² on dc motors. Recall that industry conventions categorize most of these motors as dc brush motors, dc permanent-magnet (PM) motors, or dc universal motors. As this MC² details, there are numerous caveats and sub-classifications — especially relating to motors that employ permanent magnets.
Below are some informational resources for design engineers looking to choose from and specify these motors. So check them out and be sure to bookmark designworldonline.com/MC2 to stay current on this series.
This year’s survey of trends in electric motors for motion control and automation revealed several trends and emerging developments in the use of synchronous ac motors; stepper motors, especially in closed-loop offerings; brushless motors of various types; and a smattering of specialty direct-drive offerings just making inroads.
Motion Trends: New motor breeds are smart, connected, and compact
