PG24-2430 Planetary DC Motor: Providing Reliable Power for Smart Medical Devices
In the field of medical equipment, a high-precision, low-noise power system is crucial for ensuring the stable operation of devices. Recently, a company specializing in the development of smart medical devices adopted the 24mm diameter PG24-2430 planetary DC motor in its new electric hospital bed, significantly enhancing the product's performance and user experience.
I. Project Background
The company is committed to developing smart electric hospital beds to meet the demand for efficient, comfortable, and low-noise equipment in hospitals and rehabilitation centers. However, during the initial testing phase, the R&D team found that traditional motors generated high noise levels during operation, especially at low speeds, and exhibited unstable torque output under high load, which affected the overall performance of the equipment and the user experience of patients.
II. Technical Challenges and Solutions
(1) Technical Challenges
-
Noise Issue: Traditional motors produced high noise levels during operation, particularly when operating at low speeds, with gear meshing noise being especially noticeable.
-
Unstable Torque Output: Under high load, the torque output of the motor fluctuated significantly, causing the bed's lifting and tilting functions to be less smooth.
-
Heat Dissipation Problem: After prolonged operation, the motor's temperature increased, affecting the stability and service life of the equipment.
(2) Solutions
-
Selection of PG24-2430 Motor: After multiple rounds of testing and comparison, the R&D team chose the PG24-2430 planetary DC motor. With a diameter of 24mm, this motor can deliver up to 30kgf·cm of torque, fully meeting the load requirements of the electric hospital bed.
-
Low Noise Design: The PG24-2430 motor features high-precision helical gears, optimized gear meshing angles, and significantly reduced operating noise. Additionally, sound-insulating materials were added inside the motor housing to further absorb and isolate noise.
-
Enhanced Torque Stability: The motor employs advanced closed-loop control algorithms to monitor and automatically adjust torque output in real-time, ensuring smooth operation of the bed's lifting and tilting functions.
-
Heat Dissipation Optimization: The motor housing was equipped with heat sinks, and the internal air flow channels were optimized to ensure effective heat dissipation during prolonged operation.
III. Implementation Results
-
Noise Reduction: The motor's operating noise was reduced from 45 decibels to 35 decibels, significantly improving the quiet environment in the ward.
-
Improved Torque Stability: The bed's lifting and tilting functions became much smoother, with torque output fluctuations reduced by 30%, enhancing the user experience for patients.
-
Enhanced Equipment Reliability: The motor's long-life design and optimized heat dissipation system significantly improved the stability and service life of the equipment.
IV. Customer Feedback
Since the launch of the new electric hospital bed, customer feedback has been extremely positive. A hospital nurse commented, "The new hospital bed operates very quietly, and patients hardly notice any motor noise during use. Moreover, the bed's lifting and tilting functions are very smooth, making it very convenient to operate."
V. Conclusion
The PG24-2430 planetary DC motor, with its high torque output, low noise operation, and long service life, provides a reliable power solution for smart electric hospital beds. It not only enhances the performance and user experience of the equipment but also sets a new benchmark for the development of medical devices. In the future, with continuous technological advancements, the PG24-2430 motor is expected to play a significant role in more medical devices, bringing greater convenience to patients and medical staff.
