Abstract
A gearmotor includes a motor assembly, a gear assembly, and an electronics assembly. The motor assembly includes a rotor including a rotor shaft; a stator; and a stator retention apparatus. The stator includes a core defining a core orientation feature, and a plurality of coils. The stator retention apparatus includes an apparatus orientation feature and an electronics assembly support structure. The gear assembly includes an output shaft. The electronics assembly includes a rotor shaft rotation sensor that is radially spaced from a rotor shaft position indicium, an output shaft rotation sensor that is radially spaced from an output shaft position indicium, and a magnetic sensor mounted to the electronics assembly support structure. The core orientation feature and the apparatus orientation feature engage one another to position the stator retention apparatus radially and arcuately relative to the core, such that the magnetic sensor is positioned adjacent an axial coil margin.
