Challenge
Environmental Control System (ECS) valves efficiently and reliably manage the temperature and pressure-regulated air for heating, pressurizing, and ventilating the aircraft cabin to maximize passenger comfort and safety. Precision motors used for these applications must be lightweight and compact to improve the aircraft’s fuel efficiency, provide control to ensure the proper positioning and operation of the valve, and operate reliably to minimize maintenance costs.
Portescap supplies a variety of motor technologies that are well-suited for ECS valves. Stepper motors are ideal for regulated valves, given their precise positioning capabilities, while brush DC motors are a lightweight and economical solution for on/off valves. Our Ultra EC BLDC motors can be employed by both types of valve applications, with brushless flat slotted motors (such as Portescap’s ECF range) providing a BLDC solution in an extremely compact form factor.
