Ventilator devices are important tools to support patients faced with conditions that affect normal breathing, such as pneumonia, COPD (Chronic Obstructive Pulmonary Disease), lung infections, brain injury or complications after general anesthesia. Ventilators use motor driven turbines to blow oxygen into the lungs and to remove carbon dioxide. Motors play a critical role in maintaining flow rates, pressures and I:E ratios.
A global ventilator manufacturer approached Portescap with a request to design a system with low motor noise and integrated drive electronics (2 wire BLDC) for a positive end-expiratory pressure (PEEP) blower. This device provides positive pressure to the lungs at the end of each breath to prevent lung collapse. Portescap utilized a 16ECP Ultra EC™ slotless brushless DC motor with integrated electronics for 2 wire operation in this application. In collaboration with the customer, additional value-added elements were incorporated in the assembly to reduce insulation and test time for the ventilator. The Ultra EC motor was successful in meeting the motor temperature, noise and reliability requirements. Because the application was for a critical medical device, the customer required a design and production audit of Portescap facilities, which passed successfully.
