Stepper Motors with Planetary Gear Heads for 3D Dental Scanners
NEMA 17 Stepper Motor for Scanners and Medical IT Applications | 42Q Geared Series
Improved performance in 3D printers and 3D scanners is a growing application of our stepper motors and drivers.
Our client was a dental scanner manufacturer of high-quality imaging equipment used in professional dental clinics. They were looking for a high torque stepper motor to control the movements of their new dental reader. In addition to performance, the manufacturer was also looking for a small stepper motor, as the equipment had to be compact enough for private dental clinics.
Our goal for this project was to maximize power output while minimizing the stepper motor size for the client’s compact 3D dental scanners.
Our engineers recommended the NEMA 17 stepper motors in our 42Q series. From our experience with medical applications of stepper motors, we knew that most 3D dental scanners required motor lengths between 34mm and 48mm. Stepper motors were also a better choice than servo motors for this application due to their superior holding torque (torque production at standstill) and higher torque production at low speeds for the dental scanner.
Ultimately, our hybrid stepper motor solution included the following custom specifications:
- Length: 34 mm
- Holding Torque: 58.84 Ncm
- Rotor Inertia: 38g cm2
- 1.8 degrees step angle

Stepper Motors for Automated Document Feeders
NEMA 23 Stepper Motor for Automated Document Feeder Applications | 56Q Geared Series
A Japanese global printer and photocopier machine manufacturer looked for a reliable, long-term partner to manufacture the NEMA 23 stepper motors in their ADFs (Automated Document Feeders) when total in-house production became too costly. After a collaborative process of co-designing and testing our custom stepper motors with our engineers, the manufacturer made us their exclusive supplier for stepper motors.
The client first approached us for a consultation with our design engineers. They were looking for NEMA 23 rotary hybrid stepper motors with a positioning accuracy of under 5% for their ADFs. The accuracy in motion control was required to push and pull documents through the scanner.
Our engineers proactively managed this project by co-developing custom motor specifications that were perfectly fitted to the client’s ADFs. Our engineers considered several factors, including ADF type, paper sizes, and machine operating speeds. Moreover, from our experience in printer and scanner applications, we knew that the ideal holding torque for the client’s ADFs is between 0.1Nm and 0.5Nm.
We used the standard NEMA 23 hybrid stepper motors from our 56Q series as our baseline design. Then, from the standard model, we customized the housing design and holding torque to 0.4Nm. We happily supplied custom stepper motors without regard for the client’s order volume, which was small at the beginning. Before expanding production, we provided samples of the custom hybrid stepper motors to our client, so that they could observe and test the performance in their automated document feeders to satisfaction.
Our custom stepper motors excelled in our client’s performance tests on our first design. Likewise, we hold a perfect track record in satisfying our clients’ specific needs on our first iterations of custom stepper motor designs.

Stepper Motors for Optical and Optometry Equipment
NEMA 17, 23 and 24 Hybrid Stepper Motors for Applications in Medical Imaging Equipment |
Background: As a global leader of optical imaging scanner manufacturer, our client was looking for a stepper motor manufacturer whose expertise, efficiency, and accommodation would make for a valuable long-term partner as they developed new devices and expanded their product range.
Challenges: An award-winning optometry and ophthalmic medical equipment manufacturer needed a custom stepper motor supplier for their new product developments; a new supplier had to meet their current stepper motor quality made by a Japanese manufacturer at lower cost. Further, the optical device manufacturer had many R & D projects, which required engineering support and customization from a stepper motor manufacturer. However, their stepper motor supplier at the time was unwilling to support the client’s R & D projects.
LPR Global Solutions: Initially our 2-phase hybrid stepper motors, NEMA 17 from our 42Q series, were selected as a replacement for their existing hybrid stepper motors. The client was able to inspect and test our stepper motors in their own equipment and production facilities. We were successful in replacing the client’s stepper motor needs on our first attempt, which helped gain our client’s trust in our quality and experience.
New product design and collaboration for medical imagining precision equipment
Our subsequent solutions were more interesting, as our engineers collaborated with the client to design and develop new precision optometry equipment. Due to our experience in the application of stepper motors in the medical field, this collaboration has been prolific in producing over 10 ophthalmic and optometry equipment for the client. Moreover, our involvement from the design stage helped our client save time and costs in their product development funnel. Our custom 2-phase hybrid stepper motor solution for this client expanded to include our NEMA 17, NEMA 23, and NEMA 24 stepper motors.
This relationship has since evolved into a 20-year long-term partnership that continues to produce a range of industry-leading optometry equipment for this client, who is the leading and most trusted brand by medical professionals in 114 countries.
Stepper Motors vs. Servo Motors for Medical Imaging Equipment and Devices
Our client chose hybrid stepper motors over servo motors for their ophthalmic and optical devices for multiple reasons.
- Superior position control – Stepper motors provide the unique capacity to control motor position without a separate encoder or position sensor, which lowers production costs. In contrast, servo motors require an additional encoder or sensor to identify the motor position, which makes them the less cost-efficient option. Finding high-quality, cost-efficient custom motors was important for this client, as they produced end-user medical devices.
- High Holding Torque – Stepper motors have superior holding torque, especially when compared to servo motors. As a result, they are ideal for applications in precision equipment and vision system positioning such as our client’s ophthalmic equipment, which require standstill stability.
- Smooth, Consistent Motion – Our hybrid stepper motors operate in half-step rotations and work with micro-stepping drivers for smoother motion and more consistent torque production.
With decades-long expertise in stepper motor applications in the medical field, we offer efficient custom solutions for your equipment development. We are happy to help you find the right stepper motor for your equipment, even in small order volumes. Please contact us with specifications for your own custom hybrid stepper motor needs.
