1. A control system, comprising:
- an electric machine coupled to provide power to or receive power from a DC bus;
a controller in communication with the electric machine and the DC bus, the controller being configured to;
receive a voltage from the DC bus;
compare the voltage from the DC bus to a characteristic indicative of a fault of at least one winding of the electric machine; and
take a precaution based on the comparison.

Abstract
A control system is disclosed. The control system has an electric machine coupled to provide power to or receive power from a DC bus and a controller in communication with the electric machine and the DC bus. The controller is configured to receive a voltage from the DC bus, compare the voltage from the DC bus to a characteristic indicative of a fault of at least one winding of the electric machine, and take a precaution based on the comparison.
