Abstract
A motor resolver assembly includes a resolver stator and a resolver rotor positioned radially inward of and rotatable with respect to the resolver stator. First and second relatively rotatable shield components generally surround the resolver stator and rotor to shield them from electromagnetic energy from a radially outward motor rotor and motor stator. A method of measuring speed and position of the motor rotor relative to the motor stator is also employed.
