Ventilation systems

Focus COVID-19

The need for ventilation systems around the world has increased rapidly in a just a very short time, with many countries currently stocking up and expanding their capacities. To ensure the supply with oxygen, so-called CPAP (continuous positive air pressure) machines are being used in non-invasive cases to support breathing. In intensive care, where the critically ill are generally sedated, ventilation is performed invasively by means of intubation. For manufacturers of ventilators, the controllability of the speed, the low-vibration and quiet running as well as the reliable and low-maintenance operation play a decisive role for the air flow control – properties that are an ideal match for the drives from FAULHABER.

TheFAULHABER BRC series brushless DC motorsare a suitable fit for medical technology applications. In optimized, continuous operation, the motors satisfy the requirements of the ventilator applications by delivering high-performance bearing and cogging-free running with a linear speed and torque curve. Thebrushless motors with an integrated speed controlleroperate to provide precise speed control for any desired air flow rate. Thanks to their robust construction, they are also suitable for applications actuating high loads. The motors can be operated reversibly in a clockwise or counter-clockwise direction, depending on the required control mode.

Also well suited for mechanical ventilators are the high-precision, 16 mm, high-speedFAULHABER BHx series. The 2-pole brushless BHx series, is based on an innovative and robust design and delivers high power in spite of its compact size. The BHx motors are offered in 2 distinct versions, each optimized to support a wide variety of application needs: the BHT variant is dedicated to high torque for large impulsive cycles, and the BHS version is focused on achieving very high speeds for continuous use.

The motors of the BHx series can drive variable loads with minimal speed fluctuations and ensure a smooth performance at constant speed. Furthermore, their low inertia and short response time provide high dynamic actuation . The BHx series is also characterized by and designed for low vibration and low noise, which helps to reduce fatigue and stress in the application environment, particularly for handheld instruments being used by medical staff. This provides a siginifcant advantage, especially for applications requiring direct patient interaction.
