Brushless Direct Current (BLDC) motor controllers offer flexibility for operating electric motor-driven pumps and other engine accessories. These controllers commutate the motor using a variety of control methods, depending on the application. From sensorless to resolver to hall-effect feedback, each application is properly regulated using appropriate feedback mechanisms.

The electric motor-driven product line offers advantages over gearbox-driven systems:
• Pump location within system becomes flexible
• May eliminate accessory gearbox attached to the aircraft engine with its constant input speed
• Pump flow and motor speed can be variable if required
Brushless Direct Current (BLDC) motors offer advantages over other electric motors:
• Brushes and commutator have been eliminated and the windings are connected to control electronics
• More reliable than comparable AC motor

The and service many different applications including military applications on ground and airborne platforms.

APPLICATIONS:
This 28Vdc and 270Vdc controllers are versatile and are used on oil, fuel, and cooling pump systems for military and commercial aircraft, and ground based platforms.

FEATURES AND ATTRIBUTES:
• Unique benefits include built-in redundancy to keep systems operational
• Tested in accordance with DO-160
• Hardware designed in accordance with DO-254
• Modular and reconfigurable in early stages of platform development
