Abstract
A motor assembly is provided including a stator and a rotor. The stator includes a stator main body defining a longitudinal axis, stator teeth projecting radially from the stator main body, stator windings wound around the stator teeth, and two winding terminals provided for each stator tooth extending away from the stator main body substantially parallel to the longitudinal axis. A circuit board is oriented along a radial plane adjacent the stator. The circuit board includes a central through-hole through which a rotor shaft extends, at least one magnetic sensor mounted on a surface of the circuit board around the central through-hole configured to magnetically interface with the rotor, peripheral openings arranged to receive the winding terminals of the stator, and conductive routings extending from the peripheral openings to connect the stator windings in a series or a parallel configuration and/or a wye or a delta configuration.
