What is the Longest BLDC Motor? What is the Smallest Micromotor ?

Have you ever wondered what it the longest bldc motor or the shortest brushless motor available? Or even the smallest of the smallest micromotor?


If you work in procurement for medical motors or if you are just a motor engineer working on a project that requires a small radial flux motor, this question is probably on your mind. When searching through catalogues or online resources, the length of the motor is often a critical factor but it is hard to have a complete view of the full available range.


Finding the perfect slotless brushless motor, whether it is a compact axial flux motor or a longer brushless dc electric motor, can be incredibly frustrating. Market research tells us that less than 2.5% of available options are smaller than 13 mm, and less than 2.5% exceed 90 mm length. This limited selection is a big problem for those needing the tiniest small electric motors for a compact application, and also for people who would just prefer a longer motor and are OK to compromise on other specifics!



But there are good news! You don't have to compromise on anything. Mirmex Motor can certainly create the shortest bldc motor designs for you and assist those in need, even from 2 mm of micromotor length.


Thanks to our advanced design optimization tools, we can customize a brushless dc motor and the motor windings to any specs a customer requests. On the other hand, we can also develop the longest bldc motor—who knows? It all depends on what you are looking for. But small motors are our expertise!


If you are struggling to find an ideal solution, we would love to hear from you! Connect with one of our engineers and discover how Mirmex Motor can meet your unique electric motor dc brushless needs, whether it is a micro generator or a specialized brushless dc electric motor.
