An electric motor () for controlling the lateral displacement of a shaft () connected to a rotor () of the electric motor () is provided. The electric motor () includes one or more stator conductors () for carrying a current and one or more permanent magnets () to produce a magnetic field (). The one or more stator conductors () interact with the magnetic field () when the power is applied, to purposely generate a force with an axial (Fa) and a circumferential component (Fc). The electric motor () includes the shaft () that travels along a rotor axis () in an axial direction when the power is applied, under an action of the axial component of the force. However, when the power is removed, the shaft () retracts under the action of a biasing force from a tension device ().

A system () and method () for determining whether a sample object () has a color that is within a predetermined range is provided. The system () includes a light source () capable of projecting lights having different light wavelength spectrum upon the sample object (). A controller () causes the light source () to project a first light wavelength spectrum upon the sample object (), then another, then another, and so forth. While each light is projecting upon the object, a monochromatic image capture device () captures an image having luminous intensity information. The luminous intensity information, or a subset thereof selected by an image selection tool () is then compared to the statistical range, which is derived from a plurality of images taken of a reference object ().
