Hybrid Stepper Motors | Optimized Winding and Torque

High Torque HB Stepper Motors for Medical 3D Printers, Scanners and Ophthalmic Equipment | Planetary and Spur Gears

Hybrid stepper motors are critical where precise position and speed are both required. Our synchronous hybrid stepper motors are offered in unipolar and bipolar phases, with 1.8° standard step angles, providing combined benefit of permanent magnet stepper motors, and variable reluctance motors. With both standard and custom rotary frame sizes from NEMA 16, 17, 23, and 24, and customized dynamic torques settings, hybrid stepper motors are exceptionally reliable across various torque settings, making them suitable for motion control applications requiring high torque, accuracy, power, and repeatability for high speed to low speed applications.


Our hybrid stepper motor design engineers provide customized and optimized motor specifications like speed motor frames, motor lengths, shaft size and lengths, electrical configurations, optimized windings, customized leads and connectors with each client because when global clients seek us for new hybrid stepper motors, they are also in the process of developing a new equipment. They require our stepper motor engineering expertise to find the motor that can accommodate their exact needs.


Our rotary hybrid stepper motors are being installed globally in multi-axis CNC machinery, robotics, process automation systems, automotive components, electronic banking machines (ATMs), medical 3D scanning devices, medical analyzers, ophthalmic diagnosis machines, and 3D printers in North America, Europe, and Asia.

Hybrid Stepper Motors for High Holding Torque Motion Control

Hybrid Stepper Motors, a type of DC synchronous motor with precise angular control, and high torque, plays one of the most important role in a motion control system. LPR’s hybrid stepper motors are made in Korea to have long service life and require no maintenance, because their rugged brushless designs make them stable for even high-temperature environments. Hybrid synchronous stepper motors combine the best features of PM and VR stepper motors, with powerful internal permanent magnet rotors that ensure constant speed, while the multi-toothed stator pole sets allow precise positioning without skipping steps. Our hybrid stepper motors are equipped with low resistance windings in 2 phases that are energized with a DC for high speed, and high-performance ball bearings for accurate and reliable rotary motions.

These stepper motors are best-in-class for mechanical and electrical sturdiness, improved holding torque, and repeatability of movement.

Hybrid Stepper Motor Models | Low to High-Speed Applications 

We specialize in hybrid stepper motors in square or conventional round-bodied options, equipped with a mounting flange containing tapped holes in each corner for secure fastening. The comprehensive stepper motor product range includes unipolar stepper motor drives for high-speed performance and bipolar stepper motor drives for increased torque and high-efficiency applications. We offer hybrid stepper motors with planetary gear configuration for high holding torque but also a spur type gear configuration for lower holding torque applications.


All of our hybrid stepper motors operate with low noise, minimal vibration, and reduced resonance for smooth rotation. Precisely controlled movements of automated pick and place robotics, laser cutters, and medical scanners can be achieved with these stepper motors through open-loop control system to eliminate the use of optical encoders or position sensors. However, these hybrid stepper motors are also compatible with a closed-loop stepper system for even better performance.

Stepper Motors for Automated Document Feeders

Nema 23 Stepper Motor suitable for Automated Document Feeder | 56Q Geared Series


Japan-based global printer and photocopier machine manufacturer decided to outsource all the hybrid stepper motors needed for the ADF (Automated Document Feeder) section of their printers after consulting with our design engineers. They were looking for a reliable partner to manufacture all their NEMA 23 rotary hybrid steppers so that their ADF can pull and push passing documents through their machines with a positioning accuracy of less than 5%. We offered a hybrid rotary stepper motor model 56Q series with customized design and a holding torque of 0.4Nm. This client decided to exclusively source all their motors from our shop because our engineering team proactively managed this project by co-developing the motor specification that would precisely fit the ADF function and customizing the hybrid stepper motor specifications regardless of the order size. Then, we provided sample stepper motors based on this design, and observed its fit on the Automated Document Feeder section together with our client.

Hybrid stepper motor’s specification needs to be adjusted depending on the type of ADF, the size of papers going through the printer or photocopier, and the operating speed of the machine. The general holding torque for this application is in between 0.1Nm to 0.5Nm.
