Justification of a choice of the BLDC motor and cycloidal reducer with rolling elements for an electromechanical drive of a rudder of the transport aircraft is given. Influence of ratio of a reducer and electric motor parameters is considered: factor of an electric reduction, inductance of phases and a way of formation of currents in phases on the general overall dimensions depending on chosen velocity of the electric motor.
