Among the changes to small motor design over the years has been the use of powerful rare-earth magnets to increase power density, making for smaller and more powerful motors. These motors are finding their way into medical devices, robotics, as well as the intersection of these two. Case in point; a robotic glove. Ironhand from […]

Without micromotors global logistics would be lost
Always more, always faster, always farther — everything needs to arrive at the right time at the right place. The global goods cycle keeps the economy running and presents challenges for everyone involved. Its function relies on extensive automation within the logistics chain, which would be almost impossible without an armada of high-performance micromotors. These motors often […]
Brush DC versus brushless DC motors in disposable tools
Disposable medical hand tools are seeing increased use due to their cost and hygiene benefits. Engineers who design these tools usually specify brush DC or brushless DC motors. Here we compare these two options. By Clémence Muron • Applications engineer | Portescap An early step of surgical power tool engineering is to determine whether the […]
NASA’s Perseverance rover heading to Mars with maxon drives aboard
This month, NASA will be sending its fifth rover to Mars. Its main mission is to collect soil samples that will be analyzed on Earth at a later time. The rover will also carry a helicopter that will perform the first flights on the Red Planet. maxon’s precision dc and brushless dc motors will be […]
Pedal electric cycles (pedelecs) employ FAULHABER electric motors
In many parts of the world, bicycles are central to the culture — both for recreation and practical transportation for everyday tasks such as shopping or commuting to and from work. Efforts to reduce CO2 emissions, concerns about climate change, and rising fossil-fuel costs in many areas (along with congested roadways) have only spurred more […]

When to use gears to change the inertia ratio of a motor-driven system
In any system where a motor drives a load to achieve precise positioning, velocity, or torque, the ratio of the load inertia to the motor inertia plays a significant role in determining the motor’s ability to effectively and efficiently control the load, especially during acceleration and deceleration portions of the motion profile. In this context, the […]
Motion Trends: New motor breeds are smart, connected, and compact
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. Proliferation of synchronous ac motors With construction and […]
