A position transducer system is disclosed for a limited rotation motor that includes an illumination source that directs illumination toward an illumination reflector that rotates with a rotor of the limited rotation motor, and a plurality of detector areas adjacent the illumination source for receiving modulated reflected illumination from the illumination reflector.

Optical position transducer systems and methods employing reflected illumination for limited rotation motor systems

A scanning assembly is disclosed for providing controlled movement of a mirror. The scanning assembly includes a motor shaft of a limited rotation motor, a scanning device, and a scanning device mounting unit. The mirror mounting unit includes a tapered base for coupling the scanning device mounting unit to the output shaft of the limited rotation motor. One of the tapered base and the output shaft includes a cylindrical tapered male plug having a decreasing inner diameter that decreases along a direction of coupling of the tapered base and the output shaft for engaging the tapered base to the output shaft. The tapered base includes an overall taper angle of at most about 4.0 degrees from the rotational axis of the output shaft.

Mirror mounting structures and methods for scanners employing limited rotation motors

A limited rotation motor system that includes a rotor is disclosed wherein the rotor includes a sleeve with a first open end and an a second end having an integral closed end element, and a permanent magnet that is received through the first open end of the sleeve. The first open end of the sleeve is also adapted to receive an output device, and the second closed end is for mounting the rotor within the limited rotation motor system.

Rotor shaft for limited rotation motors and method of manufacture thereof

A mirror mounting unit is disclosed for use in a limited rotation motor system. The mirror mounting unit includes a mirror, and a tapered base for coupling the mirror mounting unit to an output shaft of a limited rotation motor. In various embodiments, the tapered base may be male or female, the mirror may be formed integral with the tapered base, and the taper may be linear or non-linear.
