Redundant drive system

摘要

The invention relates to a drive system (1). The drive system (1) has at least two inverters (3, 31, 32, 33) and at least two motors (2). Each of the motors (2), each of which has a stator and a rotor, has at least one first coil system (21) and a second coil system (22) in the stator. Each first coil system (21) is connected to a first inverter (31) in an electrically conductive manner, and each second coil system (22) is connected to a second inverter (32) in an electrically conductive manner. The invention further relates to a method for the redundant operation of a drive system (1), wherein at least one motor exchanges electric energy with the second inverter (32) and/or one or more additional inverters (33) if the first inverter (31) fails.

1. A drive system, comprising:
at least two inverters; and at least two motors, each said motor including a stator, a rotor interacting with the stator, and first and second winding systems disposed in the stator, said first winding system being electrically conductively connected to a first one of the inverters, and said second winding system being electrically conductively connected to a second one of the inverters, said first and second winding systems being configured to enable the inverters to control a power distribution and/or torque distribution between the motors.
