1500PPS High-Speed Micro Stepper Motor: Zero Missed Steps
Nobody wants a micro motor that loses count. Our 10-35mm geared stepper series hits 1500PPS and stays in sync. We used a low-inertia rotor so it snaps to attention instantly—perfect for high-speed medical pumps or fast printers. It’s quiet, it’s smooth, and most importantly, it’s reliable. You get the exact position you programmed, every single time, even during rapid start-stop cycles.
Class F 155°C Protection: Big Power in Tiny 10mm Frames
Tight spaces usually mean heat problems, but we’ve got you covered. While others stop at 120°C, our micro stepper motors are rated for Class F (155°C) to handle the heat of heavy workloads. We’ve packed this durability into a tiny 10mm body designed for versatile integration into any cramped corner. It’s a true plug-and-play solution that won’t burn out or fail, even when things get hot.

Micro Stepper Motor Application Solutions
We provide ultra-compact 10mm miniature motors for lab dosing pumps. With Class F (155°C) resistance, these motors ensure non-stop 24/7 operation with nanoliter precision and zero thermal drift in IVD diagnostics.
For thermal receipt printers, we’ve pushed our 15mm series pm stepper motor to a 1500PPS pull-out frequency. Supporting 2400RPM, it ensures smooth paper feeding and instant cutter resets, eliminating step-loss during high-speed tasks.
In 4K PTZ cameras, our 25mm series uses low-inertia rotors to cancel out vibration and noise. This ensures smooth, jitter-free tracking for crystal-clear imaging and completely silent operation.
Our 20/25mm motors for electronic door locks deliver a powerful 110gf.cm torque for Access Control Systems. The low-resistance design minimizes power draw, extending battery life by over 30%.
We use 35mm motors for small to mid-sized valve and damper control. Their high torque and Class F heat resistance make them reliable for long-term industrial and HVAC pipe switching.

Testimonials
“I’ve been burned by small shops before—the first 100 micro stepper motors were okay, but the next 5,000 had step angle errors that were just all over the place. We moved our smart lock line to MAINTEX last year, and their automated production is the real deal. We’ve run 50,000 units so far, and the batch consistency is rock solid. No more wasting time recalibrating drivers on the assembly line. If you need a high-volume PM stepper motor supplier who doesn’t fake the spec sheet, Maintex’s team is the one to trust.”
Sato KenjiSupply Chain Director“Most suppliers just push standard tin-can motors, but we needed a 15mm PM stepper that wouldn’t de-magnetize in a tight, fanless medical housing. MAINTEX didn’t just tell us to ‘buy a bigger motor’—they actually reworked the claw pole geometry and upgraded us to Class F (155°C) insulation. Their guys really know their torque curves and thermal stability. Even after 2 hours of non-stop cycling, the holding torque stays steady as a rock. These guys are national motor standard drafters, and it shows.”
Dr. Stefan WeberLead Hardware Engineer“We had a nightmare interface for our CCTV PTZ mount where a standard round shaft kept slipping. I sent a rough sketch to MAINTEX, and their 70-man R&D team turned around 2D/3D CAD drawings for a custom D-cut shaft with a built-in pinion in just 48 hours. When the motors showed up, the lead wire assembly and JST connectors were already done to our exact length. They handle the messy ‘custom’ stuff so we can stay focused on the optics. Best OEM partner we’ve found in Shenzhen, hands down.”
Jason MillerProduct Design Engineer
Holding Torque is for stationary locking, but Pull-out Torque is the real-world strength during rotation. Our BY series optimizes claw pole geometry to maintain a flat torque curve, preventing motor stalling or missing steps at high PPS (pulses per second) frequencies in dynamic apps like CCTV PTZ or smart locks.
Standard round shafts often slip under load. We recommend custom D-cut or knurled shafts for a secure mechanical lock. Our 70-man R&D team provides 2D/3D CAD drawings for custom pinion or lead screw integration, ensuring a perfect drop-in replacement that eliminates assembly errors.
Inconsistency usually comes from worn dies or manual winding. We use automated production and precision progressive dies to lock step angle accuracy within ±5%. Under IATF 16949, we maintain ±10% resistance tolerance, ensuring 50,000+ unit orders perform identically without driver re-calibration.
Stalling happens when Pull-out Torque drops due to back-EMF at high speeds. We solve this by customizing coil resistance and inductance to shift peak torque to your specific operating range. This ensures stable performance even at 1000+ PPS frequencies, backed by our rigorous torque-frequency testing.
It’s about maximizing Holding Torque per milliamp. We provide custom winding for 3V-12V battery systems, delivering high instantaneous torque for clutch mechanisms while minimizing standby drain. Our engineers also consult on unipolar vs. bipolar driving to extend battery life without sacrificing response time.
Honestly, it comes down to your stepper driver and budget. Unipolar motors are great if you’re looking for a simple, cheap drive circuit. But if you’re tight on space and need every bit of power, go with Bipolar. It uses the full winding to give you much higher torque density. Whether you need the simplicity of a 5-wire/6-wire or the punch of a 4-wire setup, we build both to match your motion control needs.
Tiny motors often hit a “shaky” patch (mechanical resonance) when changing speeds. We tackle this at the source with an optimized magnetic circuit and high-grade permanent magnets to keep the flux transition smooth. This kills off most of the vibration and backlash, which is a deal-breaker for optical lens adjustment or IVD laboratory equipment where you need steady, jitter-free motion.
