Commutatorless DC motors
Avionica MRPC JSC has developed a unified series of commutatorless motors.
Electro-mechanical actuators for use in aircraft automation system (servo units, auto-throttle actuators, actuator units), as well as in different industries are developed on the basis of the presented motors.
The motors comply with international environmental requirements. Each motor has an electronic commutator designed in accordance with the particular requirements for an actuator.
