Abstract
A gear motor includes a motor having a housing with first and second endbells and a wall extending therebetween defining a housing interior and a stator and a rotor disposed within the housing interior. The rotor defines a tubular motor shaft extending through the first endbell. A gearhead is driven by the motor shaft and defines a gearhead output shaft coaxial with the motor shaft. A rod has a first end coupled to the gearhead output shaft and extends through a bore in the motor shaft. A magnetized disc is coupled to a second end of the rod and is disposed within the housing interior. A position sensor disposed outside of the housing interior generates signals responsive to rotation of the magnetized disc. The motor and gearhead output shafts may be supported on aligned bearings in the second endbell.
