Abstract
A method is provided for testing an electrical characteristic of a rotor. In one embodiment, the method may include applying current to the rotor, measuring voltage drop between first and second positions on the rotor, and evaluating the electrical characteristic of the rotor based at least on the voltage drop and the current. In another embodiment, the method may include coupling a first set of leads to a first end portion of the rotor at a first set of angular positions about an axis of the rotor. The method also may include coupling a second set of leads to a second end portion of the rotor at a second set of angular positions about the axis of the rotor. In addition, the method may include coupling the first and second sets of leads to a current source to provide a current flow through the rotor from the first end portion to the second end portion. Furthermore, the method may include engaging a first probe to the first end portion and a second probe to the second end portion to measure voltage drop.
