ABSTRACT:
The invention relates to a brushless direct current motor system and includes a switching circuit support mounted on stationary parts of the motor. The switching circuit support with electronic drive means is part of the stator and is disposed inside the rotatable housing. The axial extension of the rotatable housing functions as a drive boss whose diameter is independent of the diameter of the motor stator core and is step-wise smaller in diameter at its outer closed end than at its inner opened end.
