Abstract
A ventilator (10) comprises a ventilator stator (12) for mounting to a structure and a ventilator rotor (14) for mounting and rotation with respect to the stator. One or more wind-drivable elements (44) are mounted to the ventilator rotor. A motor (20) is provided for operation between the ventilator rotor and ventilator stator for selective motor-driven rotation of the ventilator rotor.
Claims21
A ventilator comprising:
- a ventilator stator for mounting to a structure;
- a ventilator rotor for mounting and rotation with respect to the ventilator stator, the rotor comprising one or more wind-drivable elements;
- and
- a motor for operation between the ventilator rotor and ventilator stator for selective motor-driven rotation of the ventilator rotor.

16-19. (canceled)
A ventilator comprising:
- a ventilator stator that is able to be mounted to a structure,
- a ventilator rotor that is mounted to rotate with respect to the ventilator stator when the ventilator rotor is caused to rotate by the wind,
- an external rotor motor that comprises:
- an external rotor that is mounted with respect to the ventilator rotor, and
- a stator that is mounted with respect to the ventilator stator,
- such that, when the motor is activated, the external rotor is caused to rotate, which causes the ventilator rotor to rotate with respect to the ventilator stator.
