Abstract:
Fault-tolerant electric drive systems including a machine having a rotor and a stator having coils arranged in pairs. Each coil in each pair separated by 180 degrees, a first phase (ϕA) having one of the coil pairs and a phase drive circuit connected therewith, a second phase (ϕB) having a second one of the coil pairs and a second phase drive circuit connected therewith, a third phase (ϕC) having a third one of the coil pairs and a third phase drive circuit connected therewith, and a fourth phase having a fourth one of the coil pairs and a fourth phase drive circuit connected therewith. Further included is a controller connected with the first, second, third and fourth phase drive circuits to control operation thereof.
