Abstract
A flat brushless motor of small size comprising: a thermally conductive base member; a plurality of motor coils fixedly attached to said base member; and a rotor assembly mounted proximately to said plurality of motor coils said motor assembly having a multiple pole permanent magnet incorporated therein.
Claims8
A flat brushless motor of small size comprising:
- a thermally conductive base member, the base member serving as a flux plate for the motor;
- a plurality of motor coils located adjacent to said base member;
- a thermally conductive deformable layer positioned between said plurality of motor coils and said base member to facilitate the transfer of heat from said plurality of motor coils to said base member;
- and
- a rotor assembly mounted proximately to said plurality of motor coils said rotor assembly having a multiple pole permanent magnet incorporated therein.
