Product Overview
In the highly regulated world of medical technology, mechanical failure is not an option. Devices must be incredibly compact, surgically precise, and absolutely reliable. This is where the micro planetary gearbox excels. As a premier precision manufacturer based in the Netherlands, SIEMPRE PODER engineers highly miniaturized epicyclic transmission systems that power the next generation of healthcare technology. From minimally invasive surgical robots to portable drug delivery systems, our micro gearboxes provide the immense torque and flawless accuracy required to save lives and improve patient care.

Working Principle: Power in the Palm of a Hand
Medical devices often use small, high-speed coreless DC or stepper motors due to strict space and weight constraints. However, these tiny motors lack the torque required to push a syringe plunger or actuate a robotic finger. The micro planetary gearbox solves this by mounting directly to the motor face. Utilizing tiny, precision-cut sun and planet gears, it drastically reduces the motor’s speed while multiplying its lifting force exponentially. Because the epicyclic load is shared across multiple gears, these miniaturized units can handle incredible force without stripping teeth, allowing for powerful medical actuators that fit inside a surgeon’s hand tool.
Core Advantages for Medical Applications
1. Extreme Miniaturization
Our micro gearboxes provide the highest torque-to-volume ratio available, allowing medical engineers to design highly portable, lightweight wearable devices for patients.
2. Unyielding Reliability
In life-critical pumping or surgical applications, gear failure is unacceptable. Our solid-carrier designs and hardened alloy teeth guarantee flawless operation over thousands of hours.
3. Absolute Back-Drivability
High efficiency allows surgical robotic joints to be “back-driven” smoothly by the surgeon’s hands, providing vital haptic feedback during delicate procedures.
4. Cleanroom & Biocompatibility
Units can be supplied with specialized coatings and medical-grade lubricants that prevent outgassing, ensuring they remain safe for use in sterile operating room environments.
5. Whisper-Quiet Operation
Noisy devices cause patient anxiety and distract surgeons. Precision gear grinding ensures rolling friction, keeping operating acoustics well below standard hospital thresholds.
Structure & Material Craftsmanship
Manufacturing a gearbox with an outer diameter of 16mm requires watchmaker-level precision. At EVER POWER, these micro components are machined from high-strength stainless steel alloys using specialized micro-hobbing equipment. To survive rigorous hospital sterilization processes (autoclaving), specific models feature sealed laser-welded housings and advanced polymer bearings that resist chemical breakdown.
Escenarios de aplicación típicos
- Surgical Robotics: Powering the tiny, articulated joints of endoscopic arms, providing surgeons with steady, high-torque manipulation inside the human body.
- Automated Syringe Pumps: Supplying the exact, unvarying slow-speed torque needed to dispense critical medications safely at exact milliliter flow rates.
- Powered Prosthetics: Integrated directly into bionic limbs to simulate the power of human muscles, providing amputees with strong, lightweight mobility.
Selection Guide for Medical Engineers
When specifying a drive for a medical device, consider these vital factors:
- Sterilization Environment: If the tool must be autoclaved, you must specify a unit engineered with stainless steel and high-temp, moisture-resistant seals.
- Motor Compatibility: Ensure the gearbox is designed to flawlessly mate with common medical motor brands like Maxon, Faulhaber, or Portescap.
- Positional Feedback: Select units that allow for easy integration of high-resolution magnetic or optical encoders on the rear motor shaft for closed-loop control.
Brand Comparison & Dimensional Replacements
Medical OEMs often get locked into highly expensive, single-source Swiss or German suppliers. EVER POWER offers a high-precision, highly reliable alternative from the Netherlands, providing exact dimensional equivalents to help diversify supply chains and drastically lower manufacturing costs.

Case Studies (Engineer’s Field Notes)
Application: Actuation for prosthetic finger joints.
Review: “Weight and space are our biggest enemies. We utilized the 16mm EVER POWER micro series. The torque-to-weight ratio is phenomenal, allowing our bionic hands to have a grip strength exceeding 20 lbs while keeping the battery draw incredibly low.” – Dr. David R., Lead Biomechanics Engineer.
Application: High-torque implant drivers.
Review: “Our dental tools must survive daily autoclaving. Standard gearboxes rust or seize. EVER POWER developed a custom stainless-steel solution with specialized medical grease. The drills run incredibly smooth and have survived hundreds of sterilization cycles flawlessly.” – Sarah M., Product Manager.
Application: Wearable chemotherapy delivery.
Review: “The delivery mechanism must run silently so the patient can sleep, and smoothly enough to deliver micro-doses. EVER POWER’s precision planetary gears eliminated the ‘pulsing’ effect we saw with cheaper motors, ensuring a steady, silent flow.” – Kenji A., Medical Device Integrator.

Frequently Asked Questions (FAQ)
Q: Can micro planetary gearboxes be back-driven by hand?
A: Yes, depending on the gear ratio. Ratios under 20:1 are generally easy to back-drive, which is highly sought after in robotic surgery to provide force feedback. Higher ratios (like 100:1) will resist back-driving and hold position better.
Q: Are these gearboxes safe to use in sterile environments?
A: Standard models use industrial grease, but EVER POWER offers specialized medical-grade models assembled in cleanrooms utilizing biocompatible, non-outgassing lubrication and stainless steel housings for medical compliance.
Q: How do you attach a micro gearbox to such a tiny motor?
A: We utilize laser-welding techniques, ultra-precision press fits, or micro-screws, depending on the specific motor faceplate, ensuring an absolutely rigid connection without adding bulk.
Q: Can they operate at extremely high speeds?
A: Yes. Micro DC motors often spin at 10,000 to 20,000 RPM. Our micro gearboxes utilize dynamically balanced carriers and high-speed bearings to safely reduce these speeds without overheating.
Q: Do you offer custom shaft modifications for medical tools?
A: Absolutely. We routinely machine custom output shafts featuring cross-holes, D-cuts, or micro-splines to perfectly fit the customer’s proprietary medical tools or syringe mechanisms.
