Allied Motion introduces brushless DC motor with integrated drive

December 8, 2017 By Paul Heney Leave a Comment

allied motor

Allied Motion Technologies introduces the KinetiMax 42 EB, a 42-mm diameter outer rotor, brushless DC motor with an integrated drive. Extremely compact, the KinetiMax 42 has a robust bearing system capable of handling high side loads. It has a minimum operating life of 20,000 hours. The KinetiMax has an integrated speed control loop with speed […]

What is linear behavior for DC motors?

July 6, 2017 By Danielle Collins Leave a Comment

linear behavior

When the term “linear behavior” is used to describe a system, it implies that the system’s output is directly proportional to the input.  Unlike their wound-field counterparts, permanent magnet DC (PMDC) motors exhibit linear behavior. The use of permanent magnets means PMDC motors don’t need separate field excitation, and therefore, don’t experience the electrical losses […]

High-torque EC brushless dc motors from maxon

June 29, 2017 By Lisa Eitel Leave a Comment

The EC-i 52-mm motor is one from a family of EC brushless dc motors from maxon. It’s an iron-wound internal rotor motor redesigned from 7 pole pairs to 8 pole pairs. This significantly reduces the vibration and noise output of the dc motor. Available in three voltage outputs, 18, 24 and 48 V, the 52-mm […]

Slotless brushless motor designs offer three advantages: Details on linear behavior and more

June 23, 2017 By Lisa Eitel Leave a Comment

In a recent video recorded at the Design World studios, I teamed up with my colleague Paul Heney to review the features of three motors (including slotless brushless motor options) from Koford Engineering in Winchester, Ohio.  Related article: What are the differences between slotted and slotless motors? Brushless motors are like brush motors but use electronic […]

What are the differences between slotted and slotless motors?

May 18, 2017 By Danielle Collins Leave a Comment

slotless motors

The original brushless DC (BLDC) motors were designed with slotted stators, and the majority of BLDC motors are still made this way. But this design produces cogging torque, which makes it difficult to achieve smooth motion, especially at slow speeds. To eliminate this effect, a new design was developed, eliminating the slots in the stator (which […]

Why use brushed servo motors?

May 11, 2017 By Danielle Collins Leave a Comment

The idea of brushed servo motors may seem a bit counterintuitive—most of us think of servo motors as high-performance devices used in highly dynamic applications, while brushed DC motors are low-cost solutions for mass-produced consumer devices. And, to a large extent, this is correct. But remember that “servo motor” is a fairly broad term that […]

Trends in electric motors part one: Market shifts towards smart solutions

April 18, 2017 By Lisa Eitel Leave a Comment

This year in motor design there’s been an uptick in three trends. Disposable medical devices, new consumer products, and the automation of humbler tasks are driving demand for affordable and miniature-motor options. (Read more about motor miniaturization in the second installment of this two-part Motion Trends series on electric motors here.) A related trend towards […]
