High-Performance Pump Motor Application in Medical Equipment

Pumps in medical equipment widely use brushless DC motors (BLDC) due to their technical properties and the strict requirements of medical applications. In terms of precision and stability, BLDC motors achieve accurate control via electronic commutation. With a closed-loop system (e.g., driver board feedback), flow error can reach ±2%, meeting the high-precision requirements for liquid or air delivery in infusion pumps, ventilators and other devices. Their low-pulsation characteristic (noise <40dB) further ensures patient comfort during treatment.

Brushless motors have no carbon brush wear and minimal mechanical loss, with a mean time between failures (MTBF) of more than 20,000 hours, significantly reducing the risk of medical equipment downtime caused by power component failures. During operation, energy efficiency can reach 70%-90%, much higher than traditional brushed motors, reducing equipment power consumption and heat generation, making them suitable for long-term continuous operation in medical scenarios.

Currently, the motors used in various pumps for medical equipment have a diameter of 14-36mm, typically in the 14-24mm range. Common models on the market include 1625 BLDC motor, 1718 BLDC motor, 2040 BLDC motor, 2418 BLDC motor, 2430 BLDC motor, 2838 BLDC motor, 3630 BLDC motor, etc. These are widely used in medical equipment and can be customized for different water pumps and air pumps according to various products.

As we all know, medical equipment has high requirements for components. These conventional models have been retained through generations of iterations. They have been truly recognized by the market and applied in various medical equipment after comprehensive evaluation of stability, service life, energy efficiency, precision, noise level, price range and other dimensions.
