12mm Silent Gear Motor: Acoustic Noise Minimization

The 12mm Silent Micro Gear Motor is engineered specifically for applications where acoustic noise must be kept to an absolute minimum (e.g., ≤35 dB).

Noise reduction is achieved through several design optimizations: 1) Motor Selection: Using coreless or optimized 5-pole DC motors for smooth commutation. 2) Gear Design: Using high-precision plastic or composite gears (e.g., POM, PEEK) that have excellent damping properties. 3) Lubrication: Employing specialized low-noise, high-damping grease. This solution is critical for devices used in residential, office, or medical environments.

Introduction

Detailed Parameters and Performance Data

RETEK: Near-Silent Actuation for Consumer and Healthcare

Suzhou Retek Electric Technology Co., Ltd. applies advanced acoustic engineering to this series. Every silent motor undergoes a specialized noise test in an anechoic chamber to verify the low decibel rating. We select materials based on their sound absorption and damping characteristics, ensuring the highest performance in noise-sensitive applications.

Production & Customization Services

Production includes the use of automated acoustic testing stands to measure the dB(A) level of every production batch under standard load conditions.

Custom Noise Level: Working with clients to meet very specific acoustic targets (e.g., meeting the ≤30 dB requirement for specific medical devices).
Integrated Encoder/Potentiometer: Mounting a low-noise, non-contact sensor to the rear motor shaft for position feedback without introducing friction noise.
Custom Output Flange: Designing specialized mounting interfaces with integrated damping materials.
Haptic Feedback Optimization: Tuning the gear backlash and damping for high-end haptic or tactile applications.

Service & Support

Technical Advantages and Core Design Features

Minimal Acoustic Output: Designed from the ground up to reduce motor whine and gear rattling.
Smooth Commutation: Motor selection minimizes electromagnetic noise and vibration sources.
High Damping Gears: Polymer gears absorb mechanical shock and vibration better than metal gears, significantly lowering the overall noise floor.
Precision Assembly: Tight tolerance assembly prevents gear wobble and excessive meshing noise.
Excellent Durability: Despite plastic gears, the design is often highly durable for light-to-medium loads.

Frequently Asked Questions

Common Inquiries Regarding Silent Gear Motors

Q: Do plastic gears reduce the motor's output torque?
A: Yes. Polymer gears have a lower strength rating than metal gears, meaning the maximum torque must be lower to prevent tooth failure. This is the trade-off for achieving low noise.

Q: Is the coreless motor version quieter than the brushed version?
A: The coreless version eliminates brush noise and is generally quieter due to smoother torque delivery (zero cogging). However, it is also more expensive.

Q: How do I ensure low noise in my final application?
A: Proper mounting is crucial. The motor must be isolated from the chassis using vibration-damping elastomers or rubber mounts, as the chassis can act as a large speaker, amplifying any residual motor vibration.
