Abstract
A gearmotor includes a motor assembly and a gear assembly. The motor assembly includes a rotor and a rotor bearing. The rotor is rotatable about an axis. The rotor includes a rotor shaft. The rotor bearing rotatably supports the rotor shaft. The gear assembly includes an output shaft and a gear system. The output shaft is rotatable about the axis. The gear system is configured to transmit rotation from the rotor shaft to the output shaft. The gear system includes a deformable gear and a gear bearing. The gear bearing couples the rotor shaft to the deformable gear. The deformable gear defines a plurality of teeth. The deformable gear defines an interior space. The rotor bearing and the gear bearing are received within the interior space.
