1. An electrical motor unit, comprising:

  • a main body with a drive shaft therein, the main body including the inner workings of the electrical motor and extending longitudinally in a direction corresponding to that of the drive shaft and having a cap at one end; and

    , a brush housing opposite the cap and disposed transversely to the main body, the brush housing having a central opening through which the drive shaft extends and a plurality of passageways, at least two passageways extending into the central opening and including brushes therein, and associated circuitry within the brush housing that is electrically connected to the brushes;

    the electrical motor unit being characterized in that;

    a control module is located along the main body and extends in a direction between the brush housing and the cap, the control module having various circuit links that define a circuit grid and are disposed in a receiving cavity;

    the circuit links are formed from conductive material with various electronic components disposed upon the at least some of the links to form a circuit, where at least some of the links include first contacts disposed at an access port for mating with an electrical connector to incorporate the electrical motor unit into an electrical system;

    at least some of the links include second contacts extending from the lines; and

    the second contacts being connected with the associated circuitry of the brush housing through a transversely extending electrical pathway.
