Abstract
Methods and apparatus for a motor generally comprise a motor shell, a drive unit, a motor electronics assembly configured to operate the drive unit, and a shaft coupled to the drive unit. The drive unit may comprise an axial design configured to increase the efficiency of the system. The motor may be totally enclosed, the shaft may be sealed using a labyrinth seal, and the motor electronics assembly may be contained within the motor shell. The motor may comprise shapes and materials to promote cooling by air flow and thermal conduction. The motor may further comprise a touch-sensitive interface, may operate at high speed in response to a signal, and may provide a single location for the connection of all inputs. A motor according to the present invention may have improved operating characteristics.
