ASLONG 25mm DC Motor Series Application Case: Empowering Precision Equipment Innovation and Upgrading

introduction
Under the trend of Industry 4.0 and miniaturization of smart devices, an international medical equipment manufacturer is facing the pain points of traditional drive systems being too bulky and consuming too much energy. ASLong, with 20 years of experience in the research and development of micro motors, has customized a 25mm DC motor solution for it, successfully reducing equipment volume by 40% and energy consumption by 35%.

Customer Challenge

The customer's latest generation portable infusion pump requires:

Drive unit with diameter ≤ 25mm

Continuous operation noise<30dB

10000 hours maintenance free lifespan

Support 12V/24V dual voltage switching

Solution

The ASLONG technical team has achieved three major innovations within the 25mm standard framework:

Magnetic circuit optimization design

Using neodymium iron boron arc-shaped magnetic steel, the torque is increased to 45mN · m under the same volume, meeting the high-precision flow control requirements.

Breakthrough in Silent Technology

• Unique "Three stage Anti backlash Gear Structure"

Ceramic bearings+special grease lubrication

The actual operating noise is only 28dB (at a distance of 30cm)

intelligent temperature control system
Built in NTC temperature sensor, automatically adjusts the speed through PWM, maintaining a speed stability of ± 1% for the motor in an environment of -20 ℃~60 ℃.

Implementation effectiveness

Volume optimization: The overall thickness of the machine has been reduced from 58mm to 35mm
Energy Efficiency Improvement: Daily Electricity Consumption Reduced from 18Wh to 11.7Wh
Reliability verification: Accelerated aging test shows performance degradation<3% after 6 million runs
Mass production cost: Modular design increases assembly efficiency by 60%

Industry Extension Applications
The technical solution has been successfully replicated to:
Industrial field: Semiconductor wafer handling robotic arm (positioning accuracy ± 0.05mm)
Consumer electronics: panoramic camera gimbal (increased battery life by 2.5 hours)
Service robot: haptic feedback joint (response time<5ms)

conclusion
This case proves that micro DC motors have evolved from simple power components to the core unit of intelligent systems. ASLONG will continue to innovate through the three in one approach of "materials structure control" to help partners break through the physical boundaries of their products.
