<p>The invention describes a method and a device for redundantly supplying several electric servomotors or drive motors (14, 15) by a common power electronics unit (10), particularly in an aircraft, wherein the power electronics unit (10, 20) contains a number of electronic motor control units (11, 12), and wherein the electric motors (14, 15) are operated with nominal power if the electronic motor control units (11, 12) are fully functional. According to the invention, the motors (14, 15) are operated with the available residual power of the motor control units (11, 12) if partial failure of the motor control units (11, 12) occurs. The motors may be operated sequentially or simultaneously according to preferred embodiments of the invention.</p> |
