Abstract:
1. A motor assembly comprising: a motor including: a printed circuit board (PCB) configured to control electric coil-powering current to the coil to electromagnetically urge the rotor to rotate, the PCB having a top surface facing away from the stator coil; a PCB housing that encapsulates the PCB, wherein the PCB housing includes a top housing layer overlying the PCB and a bottom housing layer underlying the PCB; top, middle and bottom apertures that respectively extend through the top housing layer, the PCB and the bottom housing layer; an electrically-conductive PCB contact on the PCB's top surface adjacent the middle aperture; an electrically-conductive fastener that secures the PCB to the motor, the fastener including: a fastener-to-coil conductor in the motor that electrically connects the shank structure to the coil; for the coil-powering current to flow from the PCB contact, through the fastener's head structure and through the shank structure to the fastener-to-coil conductor in the motor to power the coil.
