CT (computed tomography) scanners are the core imaging tools in modern medical equipment, and are widely used to diagnose diseases, fracture examinations, tumor detection, etc. As CT equipment requires high-speed rotation and high-precision scanning, its key components such as rotating frames, patient beds, cooling systems, etc., must be characterized by high stability, low noise, long life, and precise control. Therefore, the choice of motor is crucial.
A U.S. medical device manufacturer wanted to improve the performance of its CT scanners and was looking for a more efficient and stable drive solution. BG Motor was invited to supply a brushless DC motor (BLDC Motor) that meets the requirements of high precision, high speed and low noise for use in the CT Gantry, cooling fan and patient bed.
With the legacy CT equipment, the customer encountered several challenges:
1. The rotating frame motor is noisy, which affects the imaging quality
Conventional motors generate high mechanical noise and vibration, resulting in degraded image quality.
2. The motor has a short life and high maintenance cost
The carbon brushes of traditional brushed motors are prone to wear and tear and need to be replaced regularly, increasing maintenance costs and downtime.
3. The efficiency of the cooling system is low, and the X-ray tube is easy to overheat
Inefficient heat dissipation affects the continuous operation of the CT device and can cause scans to be interrupted.
4. The positioning accuracy of the patient's bed is insufficient
Traditional motors have slow response, making it difficult to achieve precise fine-tuning, which affects the accuracy of doctors' diagnosis.
In response to these challenges, BG Motor provides customers with high-performance brushless DC motor (BLDC motor) solutions for critical components such as CT swivel frames, cooling fans, and patient beds.
1. Gantry Motor
High-speed brushless motor (BLDC 4000 RPM) is used to ensure that the rotating frame is stable, high-speed and jitter-free.
Low-noise, low-vibration design optimizes image clarity and improves CT scanning accuracy.
Maintenance-free, 3 times longer life than traditional brushed motors, reducing downtime.
2.Cooling Fan Motor
High airflow, low power consumption brushless fan motor to ensure continuous cooling of the X-ray tube.
30% increase in energy efficiency, reducing hospital operating costs and supporting 24/7 operation.
3.Table Motion Motor
Precise control of brushless motor to achieve 0.1mm positioning accuracy±patient bed.
Smooth start-up without impact to ensure a comfortable patient experience and enhance the convenience of doctors.
Fast response time, reduce patient movement time, and improve hospital scanning efficiency.
1、Customized motor design to meet the needs of different CT equipment.
2、Remote technical guidance to ensure that the customer team can complete the motor integration quickly.
3、Product quality assurance, up to 3 years warranty service.
4、Global logistics support to ensure on-time delivery and avoid supply chain disruptions.
With BG Motor's brushless motor solution, the medical device manufacturer has been able to improve the stability, image quality, and longevity of its CT scanners. The equipment runs quieter, the images are clearer, and the hospital feedback is good. Maintenance costs are reduced by 40% and products are more competitive in the market. The customer decided to work with BG Motor for a long time and planned to adopt a brushless motor solution in more medical imaging equipment.
