Abstract

The rotor of the wind motor has a helical blade mounted on a horizontal shaft (1) which is free to rotate in bearings. The helical blade has each helix extending through 180 deg. The radial length of the blade increases along the axis of rotation. The rotor is enclosed in a profiled housing (7) which has one end mounted on a support which can rotate about a vertical axis (11). The other end is mounted on rollers (13) which run on a circular track so that the rotor can be aligned to face the direction of the wind which enters at the smaller diameter. On the edges of the blade are welded two strips (5, 6) which are at 90 deg. to the edges two which they are welded.
