PCT No. PCT/RO81/00004 Sec. 371 Date Jul. 30, 1982 Sec. 102(e) Date Jul. 30, 1982 PCT Filed Aug. 4, 1981 PCT Pub. No. WO82/01965 PCT Pub. Date Jun. 10, 1982.The invention refers to a brake electrical asynchronous motor with short-circuited rotor and double drive, where its magnetic field simultaneously generates both the revolving torque on the rotor, and the electromagnetical force for deblocking the brake. The motor, according to the invention, is characterized by a constructive system with a normal stack of statoric sheets, elongated by a supplementary stack of statoric sheets, having the same cross-geometry as the normal stack of statoric sheets, with an excitation winding common to both, a normal stack of rotoric sheets with the cage rods elongated into the area from under the supplementary stack of statoric sheets, and separated by stacks of teeth between which are created slots with the same shape with those in the area of the normal stack of statoric sheets, but opened towards the inside and short-circuited through these openings by the short-circuiting ring, located in this area. When power supplied at the statoric winding, between the front surface of the stacks of teeth that separate the rotoric cage rods in the area from under the supplementary stack of statoric sheets, and the adjacent front surface of the brake deblocking movable armature an axial attraction electromagnetic zone appears, being generated by the summed action of the magnetic field created by the current flowing through the short-circuiting ring, and of the magnetic field created by the statoric excitation winding in the area of the supplementary stack of statoric sheets, force that nullifies the pressure between the friction faces given by the pressure spring and the braking torque, disappears.
