A method and a device for redundantly supplying several electric servomotors or drive motors by a common power electronics unit, particularly in an aircraft, wherein the power electronics unit contains a number of electronic motor control units, and wherein the electric motors are operated with nominal power if the electronic motor control units are fully functional. The motors are operated with the available residual power of the motor control units if partial failure of the motor control units occurs. The motors may be operated sequentially or simultaneously.
