Electric motor driven pumps (EMP) for aerospace applications. Parkers ability to design and manufacture all major elements of our EMPs including, pump, motor, motor controller, and associated software, leads to a highly integrated and efficient EMP solution. EMPs use electric input from either aircraft generators or batteries. Parker motors can be designed to operate with a variety of electric-power inputs including; fixed-frequency AC, variable-frequency AC, 28VDC, 270VDC, and others. Parker motor controllers and associated software can be tailored for specific motor types and support unique power-management requirements.
