Design and application of coreless motors in artificial blood pumps

An artificial cardiac assist device (VAD) is a device used to assist or replace heart function and is commonly used to treat patients with heart failure. In artificial heart assist devices, the coreless motor is a key component that generates rotational force to promote blood flow, thereby maintaining the patient’s blood circulation. This article will discuss the design and application of coreless motors in artificial blood pumps.

First of all, the design of the coreless motor needs to take into account its special working environment in artificial blood pumps. Since artificial heart assist devices need to operate for a long time, coreless motors need to be efficient, stable and reliable. In addition, since its operation requires direct contact with blood, the design of the coreless motor also needs to take into account biocompatibility and anti-thrombotic properties. Therefore, coreless motors usually use special materials and coatings to ensure their long-term stable operation in the blood.

Secondly, the use of coreless motors in artificial blood pumps needs to take into account its impact on blood flow. The coreless motor drives blood flow through centrifugal force generated by rotation, so its design needs to take into account gentle handling of blood to avoid excessive shear force and pressure on the blood. At the same time, the operation of the coreless motor needs to match the circadian rhythm of the human body to ensure stable and effective blood circulation.

In practical applications, the design and application of coreless motors in artificial blood pumps need to work closely with other components, such as sensors and control systems. Through precise control and monitoring, the coreless motor can achieve precise regulation of blood flow and pressure to meet the needs of different patients.
