• a housing;
• a stator coupled to said housing and comprising a plurality of driving coils;
• a rotor rotatably coupled to said housing about a rotational axis, said rotor comprising a plurality of permanent magnets arranged in a concentrated array to generate a flux concentrated on said plurality of driving coils;
• and
• an impeller coupled to said rotor to rotate about said rotational axis for generating a flow of air through the passage of the seat bottom and the seat back cushion of the vehicle seat;
• said rotor comprising a first side and a second side with said impeller mounted to said first side and said second side facing said stator, with said plurality of permanent magnets arranged in a concentrated array to generate said flux about said second side and in an axial direction toward said plurality of driving coils.
