Abstract: An electric motor is provided. A rotor sensor mechanism is operable to sense a condition of the rotor. The rotor sensor mechanism includes a target component, a radial sensor, and a sensor carrier. The target component comprises a shutter wheel fixed relative to the rotor for rotational movement therewith. The shutter wheel includes a plurality of circumferentially spaced, radially projecting radial target teeth. The radial sensor is configured to sense the target teeth. The radial sensor is at least generally axially aligned with the radial target teeth and faces radially toward the radial target teeth. The sensor carrier adjustably supports the radial sensor on the motor frame assembly so as to permit the radial sensor to be selectively positioned relative to the radial target teeth.
