1. FAULHABER

Established: 1947
Headquarters: Schönaich, Baden-Württemberg, Germany
Main Products: Coreless DC micromotors, brushless DC micromotors, flat motors, stepper motors, linear motors, micro planetary gearboxes, spur gearheads, encoders, motion controllers

Company Overview

FAULHABER was founded by Dr. Fritz Faulhaber Sr., whose 1958 patent for a self-supporting, ironless, skew-wound rotor coil — the so-called FAULHABER winding — remains the core of the company's motor technology to this day. Based in southern Germany and operating manufacturing sites across Europe and the United States, FAULHABER is widely regarded as the global benchmark for high-precision miniature and micro drive systems. Its product catalogue spans DC micromotors from as small as 6mm in diameter up through brushless and stepper variants, each combinable with a library of precision gearheads, encoders, and controllers to form complete drive packages.

The absence of an iron core in FAULHABER motors eliminates cogging torque entirely, producing exceptionally smooth rotation at any speed — a property that makes these motors the standard choice wherever motion quality matters more than cost. Customers include leading names in surgical robotics, aerospace actuation, laboratory automation, and high-end optics. For OEM engineers specifying a miniature brushless DC motor or a micro DC motor with encoder for a precision instrument, FAULHABER's combination of performance, documentation depth, and global distribution network is difficult to match.

Main Products: Brushless slotted DC motors, brushless slotless (ironless) DC motors, coreless brush DC motors, disc magnet stepper motors, can-stack stepper motors, micro gear motors, encoders, drives

Company Overview

Founded in Geneva in 1936 and now a brand within Regal Rexnord, Portescap brings more than eight decades of miniature motor engineering to a product portfolio that covers virtually every technology type in the miniature brushless DC motor and miniature stepper motor categories. The company is particularly well known in the surgical power tool market, where its autoclavable brushless motors — engineered to withstand hundreds of sterilization cycles — have become a design standard for handheld drills, shavers, and robotic surgical systems.

Portescap's disc magnet stepper motors are another area of genuine differentiation. Using a unique thin-disc magnet rather than a conventional can-stack design, these motors achieve finer step resolutions and higher acceleration than any competing permanent magnet stepper in the same envelope — making them widely used in clinical diagnostics, infusion pumps, and pipetting systems. For buyers who need a miniature planetary gearbox matched to a brushless or stepper motor, Portescap offers a broad range of gearhead options with verified compatibility across the motor range.

Headquarters: Akishima, Tokyo, Japan
Main Products: DC coreless micromotors, brushless DC micromotors, micro planetary gearheads, encoders, control boards, motion units, hollow-shaft micro motors

Company Overview

Orbray's path into micro motors began not in a motor factory but in a jewel workshop. Founded in 1939 as Namiki Seisakusho to manufacture precision jewel bearings for electric meters, the company spent decades mastering the cutting, grinding, and polishing of hard materials at tolerances measured in microns. That heritage of extreme precision in mechanical manufacturing eventually led to the development of rare-earth magnet technology and, in 1973, the creation of what was at the time the world's smallest DC coreless motor at 10mm in diameter.

What followed is a story of sustained, methodical miniaturization. By 2004, Orbray had developed a 1.5mm geared motor — recognized with Japan's Prime Minister's Prize in 2006 — small enough for use inside ultrasonic endoscopes. By 2014, the company had produced a 0.6mm diameter brushless motor, still among the smallest in the world. Today, Orbray also produces a 0.9mm geared motor aimed at peripheral vascular catheter applications, where reaching the narrow branching vessels beyond the main arteries requires an actuator smaller than anything previously possible with conventional manufacturing methods.

The product range for standard OEM customers covers coreless DC motors from 1mm to 30mm in diameter, matched with high-precision micro planetary gearheads, encoders, and control boards. A notable specialty is Orbray's hollow-shaft micro motor, which allows optical fiber to pass through the motor axis — enabling compact optical actuator designs for OCT imaging, endoscopy, and industrial inner-wall metrology systems. For buyers in the medical imaging, camera lens drive, or high-end RC servo markets, Orbray's combination of extreme miniaturization capability and Japanese precision manufacturing consistency makes it one of the most technically credible micro motor manufacturers in the world.

Company Overview

Mirmex Motor is a technology company founded by Dr. François Baudart, whose doctoral research at the Université catholique de Louvain and post-doctoral work at EPFL in Lausanne produced a patented method of printing motor windings on flexible PCB material rather than winding them wire by wire. This seemingly incremental change has significant practical consequences: printed winding geometries can be optimized by software in ways that are physically impossible with conventional wire winding, producing motors with higher copper fill factors, lower thermal losses, and higher power density than equivalent-size catalogue motors from established suppliers.

The company produces custom micro brushless DC motors and slotless BLDC windings for applications in medical technology, surgical robotics, aerospace, and precision instrumentation. Mirmex holds ISO13485 certification and FDA 21 CFR 820 compliance, making its motors eligible for use in regulated medical devices — including active implants, surgical drills, miniature medical pumps, and motorized prosthetics. Unlike catalogue motor suppliers, Mirmex designs each motor to the customer's application: the company does not sell standard products off a shelf, but rather delivers optimized custom solutions in prototypes within a few weeks and moves to mass production once the design is validated.

For OEM engineers who have reached the limits of what Faulhaber or Portescap catalogue motors can deliver — in terms of efficiency, form factor, or operating environment — Mirmex offers a credible and faster alternative to custom motor development at a Swiss or German supplier.

Position

European deep-tech micro motor manufacturer targeting high-end custom applications. The strongest option for teams that need a motor designed around their specific requirements rather than an off-the-shelf part adapted to fit.

How to Choose the Right Micro Motor Manufacturer

The ten manufacturers above span a wide range of capabilities, price points, and geographic origins. Here is a practical framework for narrowing down your options:

If precision and motor performance are the primary requirement

Start with FAULHABER or Portescap. Both companies have decades of application engineering data, the widest range of combinable accessories (gearheads, encoders, controllers), and the deepest technical support infrastructure. For a miniature brushless DC motor or a micro DC motor with encoder going into a surgical robot or a high-end laboratory instrument, the documentation and reliability history these suppliers offer is worth the price premium.

If extreme miniaturization is required

Orbray is the only commercially active manufacturer producing motors below 1mm in diameter at production volume. For standard micro motor applications below 10mm, both Orbray and Ineed Electronics are relevant — Orbray for precision and reliability, Ineed for high-volume cost efficiency.

If you need a custom motor designed from scratch

Mirmex Motor's printed winding technology enables designs that cannot be achieved through any catalogue motor supplier. If your application requires a motor optimized to a specific form factor, efficiency target, or environmental requirement, and the volume justifies a custom development program, Mirmex is the strongest European option.

If you are sourcing from China and quality certification matters

Toosyn, Keshuo Motor (motormicro.com), and VSD Motor all hold IATF16949 certification alongside ISO9001, which places their manufacturing process discipline significantly above the average Chinese micro motor factory. For automotive or medical device supply chains that require this level of certification, these three are the most credible Chinese options among the manufacturers reviewed here.

If product breadth and volume are the priority

TT Motor covers the widest range of motor technology types — brushed DC, brushless DC, coreless, stepper, gear motor — from a single supplier, with established export infrastructure to over 80 countries. For buyers who want to consolidate their micro DC gear motor, N20 micro gear motor, and mini vibration motor sourcing into one supplier relationship, TT Motor is a practical choice.

Frequently Asked Questions

What is a micro motor and what diameter range does it cover?
A micro motor is generally defined as an electric motor with an output of 3 watts or less, or — in practical procurement terms — a motor with a housing diameter of 38mm or below. The term covers micro DC motors, micro brushless DC motors, mini gear motors, miniature BLDC motors, and micro stepper motors. Motors above 38mm are typically referred to as small motors or gear motors rather than micro motors.

What is the difference between a coreless motor and a standard DC motor?
A coreless motor — also called a hollow cup motor or ironless motor — has no iron core in its rotor. Instead, the rotor is a self-supporting copper coil that rotates around a fixed cylindrical magnet. This eliminates cogging torque (the stepping sensation in iron-core motors), reduces rotor inertia for faster acceleration, and lowers electrical inductance for better controllability. The trade-off is lower peak torque compared to an iron-core motor of the same size. Coreless motors are the preferred choice for applications requiring smooth rotation, fast response, or precise speed control — including micro brushless DC motors used in surgical tools and camera drives.

Which micro motor manufacturers supply to the medical device industry?
FAULHABER, Portescap, Orbray, and Mirmex Motor are the most established suppliers to the medical device OEM market, all holding ISO13485 certification or equivalent quality management systems for medical applications. Among Chinese manufacturers, Toosyn and Keshuo Motor (motormicro.com) hold IATF16949, which represents comparable process control discipline and is accepted by some medical device supply chains.

What is an N20 micro gear motor and where is it used?
The N20 is a widely recognized form factor for a micro DC gear motor: a small brushed DC motor (typically 10mm–12mm in diameter) attached to a compact metal planetary or spur gearbox, resulting in an overall motor-gearbox unit roughly 12mm in diameter and 20–35mm long depending on gear ratio. N20 motors are used in smart locks, robotic grippers, coin sorters, miniature conveyors, camera focus mechanisms, and consumer electronics. TT Motor and Ineed Electronics are among the Chinese manufacturers producing N20 micro gear motors at production scale.

What should I ask a micro motor manufacturer before placing an order?
Key questions include: What is the rated life at the intended operating load and speed? Can you provide a test report or datasheet specific to this motor, not just catalogue values? What are your quality certifications and what do they cover? What is the minimum order quantity for standard and custom variants? Can you provide a sample before production? What is your lead time for production quantities? For motors going into regulated applications (medical, automotive), also ask: What traceability documentation do you provide, and what is your process for handling non-conformances?

Conclusion

These 10 manufacturers represent the range you're likely choosing between — from precision-focused Swiss and Japanese players for medical and optical applications, to high-volume Chinese manufacturers built for automotive and consumer electronics scale. The right fit really comes down to your tolerance requirements, order volume, and how much engineering support you need during design-in.
