Q: What’s in store for the medical device sector in 2014?

High end ventilation and BPAP equipment continually require high efficiency at high speeds for optimum flow generation. As the equipment strives to improve on performance without being noticed by the patient, advancements in motion technology must drive this.

A new coil technology, developed by Portescap, utilizes an enhanced high efficiency magnetic circuit (up to 91% efficient) that drastically reduces both iron and recirculation losses to offer low operating temperatures at high speeds. The new patent pending motor coil also achieves higher available torque and mechanical power than similar size high speed motors in the market.

As a result, the new ECS motor stays up to 30% cooler, thus extending the life and reliability of the blower, and allows overall ventilator size reduction. Finally, by being capable of being driven harder, ECS allows for the design of ventilators that more closely match a patient’s breathing pattern by reducing pressure-rise time down to 90 to 100 milliseconds, enhancing their comfort level and therapy acceptance.
