ABSTRACT:
An improved, brushless, slot-less DC motor is disclosed which includes a plurality of ring shaped permanent rotor magnets affixed to the motor shaft and magnetized to have contiguous pole faces extending about the circumference thereof. A module plastic housing impregnated with powder metal particles is provided as a magnetic shunt to eliminate prior art ferrite-oxide laminations while assuring concentration of the rotor's magnetic flux into coils positioned in the physical air gap between the rotor and stator housing.
